Lanxess reveals highly sustainable Scopeblue composite material series
PA6 glass fiber-reinforced compound under Lanxess’ new Scopeblue series is made from 92% sustainable raw materials, with content goals headed toward 100%.
Lanxess (Cologne, Germany) introduces its latest product, Durethan BLUEBKV60H2.0EF, a glass fiber-reinforced compound that uses 92% sustainable raw materials, more than other prime quality glass-fiber-reinforced plastic the company notes. The new easy-flowing plastic grade is the first product in Lanxess’ new Scopeblue series, which identifies products that either consist of at least 50% circular (recycled or bio-based) raw materials, or whose carbon footprint is at least 50% lower than that of conventional products.
“A carbon-neutral future can become reality only if we start using more sustainable products,” says Frederique van Baarle, who heads the High-Performance Materials (HPM) division at Lanxess. “Our first product marketed under the Scopeblue brand represents a real solution for the circular economy. The compound is a certified premium material that’s based on sustainable raw materials.”
For example, cyclohexane is one raw material used in the production of the polyamide-6-based (PA6) product, and comes from a sustainable source, meaning it is either bio-based, recycled bio-based or produced by means of chemical recycling. Durethan BLUEBKV60H2.0EF is also strengthened with 60% by weight of glass fibers comprising industrial glass waste instead of mineral raw materials. Moreover, the alternative raw materials that Lanxess uses in the precursors for PA6 are chemically identical to their equivalents of fossil origin (“drop-in solutions”), so Durethan BLUEBKV60H2.0EF is reported to exhibit the same characteristics as the virgin material and can be processed just as easily using the same production tools and facilities with no conversion work needed.
“This high-strength, high-rigidity structural material can be deployed wherever its purely fossil-based equivalent, Durethan BKV60H2.0EF, has traditionally been used in series production — so in automotive construction for the production of car front ends, brake pedals and oil pans,” says Dr. Guenter Margraf, head of global product management at HPM.
Nevertheless, developers are setting their sights on more than 92% sustainable raw materials. “We’re currently working on increasing the content of sustainable raw materials in this compound to 100%,” says Margraf. This requires ammonia synthesized with carbon-neutral hydrogen. Over the medium term, the specialty chemicals company is also planning to replace the additives used in its plastics with sustainable equivalents.

Solico delivers lightweight package for Aeolos all-carbon yacht
Solico, a leading composite engineering specialist for the maritime, defense, architecture and industrial sectors, has announced its latest marine collaboration with Aeolos Composites, having engineered the new Aeolos Performance 30, a striking new all carbon 30ft sailing yacht built in the Middle East.
The Aeolos Performance 30 (P30) is a lightweight carbon racing yacht, optimised for single and double handed sailing that was conceived by Aeolos Composites’ founder, Hans Genthe during the Covid-19 lockdown in Dubai in summer 2020. Due to the ongoing pandemic, the project was completed entirely remotely.
In early 2021, Aeolos Composites commissioned Solico to review and optimise the existing structural design, define laminate lay-ups, and perform the structural verification (according to ISO 12215) of the P30 hull, deck, coach roof, bowsprit, keel, and rudder.
Carbon fibre materials were a key part of the P30 design concept, minimising weight and producing a simple, light, and fast yacht. Solico worked with the ISO 12215-5 material properties, along with preferred carbon fibre formats readily available to Aeolos, to conduct a detailed FEA analysis of the components and reduce structural weight to a minimum. The P30’s hull, deck and internal structure were completed first, after which the focus shifted to appendages and additional structures.
One of the novel features of the P30 is the cleverly hinged carbon fibre bowsprit that allows bows to mooring in European marinas that do not permit a bowsprit over the dock. Large enough to project the yacht’s downwind sails well clear of the foretriangle, but able to pivot upwards after sailing, the slender tapered composite sprit provided challenges for the engineers. Several iterations were required to define the final structure that could support gennaker luff loads and satisfy the critical buckling load cases without adding additional weight at the bow of the yacht.
The P30 uses a completely unique full composite construction for its keel, a novel solution which pushes the design limits to new levels. The composite keel structure will be put through extensive tests during the sea trials to ensure maximum performance and uncompromised safety.
Solico also produced a full construction drawing pack detailing laminate sequences and additional reinforcements required around all highly loading fittings, such as chainplates, winches, and sail tracks, which had been considered in the structural verification.
Whilst the Solico engineers would typically like to visit the client and shipyard before and during the build, engineering the composite structures of the Aeolos P30 during the pandemic necessitated an entirely online approach. With a suite of digital tools in place, design review meetings, interim and final reports were managed seamlessly, with both Solico and Aeolos commenting on how well the communications flowed, despite the thousands of kilometres between the Netherlands and the UAE.
“The P30 has been a great project to work on,” commented Matej Prevc, lead engineer, Solico. “We often note that some of our marine projects have further weight saving potential which, due to more conservative design considerations driven by specific vessel class regulations or other commercial factors, we are not able to exploit. The P30 was a fantastic opportunity for the team (many of whom are sailors themselves) to really push the boundaries and develop a fully weight optimised carbon structure, maximising performance on the water.”
With P30 hull #1 finished and painted, fit out underway and the yacht due to hit the water in the very near future, the Solico team will be eagerly awaiting feedback from the first sea trials in Dubai. Several more P30’s are already in build with Aeolos Composites looking forward to expanding the class both locally in the UAE as well as in Europe.

Tecniplas supplies composite silos for manufacture of pectin
The composite silos supplied by Tecniplas will be part of the production process of pectin in the food industry. Pectin is a texturizing agent based on citrus fruits.
Cargill's (Wayzata, Minn., U.S.) soon-to-be-inaugurated pectin factory in Bebedouro, Brazil, has composite silos manufactured by Tecniplas (Cabreúva, São Paulo, Brazil). Pectin is a texturizing agent based on citrus fruits, and the silos supplied by Tecniplas will receive the orange peels that will be part of the production process of this raw material for the food industry.
At other Cargill plants around the world, silos of this type are made of duplex steel, a type of noble metal alloy. Tecniplas’ composite silos are said to have proved to Cargill the adequacy of composites, not only in terms of design versatility but also in chemical and mechanical resistance.
Of the four largest silos supplied to Cargill, two have a diameter of 4,500 millimeters and two at 5,000 millimeters. “The manufacture of the rectangular bottom was unprecedented for Tecniplas and the biggest challenge of this project. As it is a unique piece, we developed all the molds from scratch,” Luís Gustavo Rossi, director of Tecniplas, explains. Tecniplas reportedly produced 18 different “special equipments” for this project, including the silos.

Solvay and 9T Labs mass-productionise composite AM parts
Solvay is working with advanced manufacturing solution OEM, 9T Labs to help bring additively-manufactured CFRP composite parts to mass production.
The joint effort enables 9T Labs’ additive manufacturing technology to produce low-to-medium volume size parts for the aerospace, medical, luxury/leisure, automation, and oil & gas industries.
Solvay will focus on the development of carbon fibre-reinforced polyetheretherketone (CF/PEEK), CF-reinforced bio-based high performance polyamides and CF-reinforced polyphenylene sulfide (CF/PPS) composite materials. The partnership significantly expands the types of neat and carbon fibre-reinforced materials portfolio that 9T Labs currently offers to customers.
“With 9T Labs’ innovative process and equipment and Solvay’s high-performance thermoplastic materials, we are well positioned to address problems that have long plagued manufacturers in many industries trying to use advanced composites — namely high incremental costs, high scrap, and problems achieving repeatability and traceability at high volumes,” explained Marco Apostolo, director of technology at Solvay. “We believe this collaboration will help solve many challenges and will open entirely new markets and mass production applications to CFRP materials.”
Solvay offers a portfolio of high-performance thermoplastic polymers and expertise in the production of thermoplastic composite prepreg tape. As one of the leaders in thermoplastic composites, Solvay brings expertise in the engineering of production processes to ensure the technology can be integrated seamlessly into manufacturing lines.
“For the fabrication of structural parts metals still prevail because the manufacturing of structural CFRP parts has not been cost-competitive,” added Giovanni Cavolina, 9T Labs’ co-founder and chief commercial officer. “The Red Series platform in combination with Solvay’s high-performance and recyclable materials will change this and make CFRP parts more sustainable, accessible and cost-competitive, especially at higher volumes.”
9T Labs’ hybrid manufacturing technology enables high-performance structural parts in challenging small-to-medium size and thick sections to be produced in carbon fibre-reinforced thermoplastic composites in production volumes ranging from 100 to 10,000 parts/year.

Fraunhofer commissions automated Engel production cells for thermoplastic composite R&D
Fraunhofer PAZ pilot plant center installs v-duo 700 vertical machine and duo 900 injection molding machine to combine thermoplastic composite processes with a variety of injection molding technologies.
Fraunhofer’s Pilot Plant Centre for Polymer Synthesis and Processing PAZ located in Schkopau, Germany, recently commissioned two Engel (Schwertberg, Austria) machines to strengthen its research and development (R&D) of lightweight applications using thermoplastic composites. The two state-of-the-art production cells enable the integration and fully automated production of functional composite components and are now available for customer projects.
“Engel combines a great deal of know-how in lightweight construction with thermoplastic composites and many years of experience in injection molding and the automation of series processes. This is a prerequisite to developing particularly cost-effective series production processes for the automotive and aerospace industries,” says Franz Füreder, vice president, automotive, at Engel. “The two new Engel systems at the Fraunhofer PAZ make it possible to combine thermoplastic-based composite processes with a variety of injection molding technologies, such as foaming or coining.”
From monomer to polymer synthesis and plastics processing on a pilot scale, to the tested series component, Fraunhofer PAZ says it develops new production processes and technologies along the entire value chain of lightweight components. Thermoplastics-based lightweight construction is one development focus, which it shares in common with Engel. “On the one hand, thermoplastic composites enable excellent cost efficiency in series production,” Füreder notes. “On the other, these materials can be returned to the material cycle easily.”
Engel delivered a v-duo 700 vertical machine, which was combined with an Engel easix articulated robot and a large IR oven. An Engel duo 900 injection molding machine with a horizontal clamping unit and two Engel easix robots make up the second commissioned production cell. A vertical IR oven is located above the clamping unit of the latter, enabling fast, hot handling of thermoplastic sheets and blanks made of unidirectional (UD) tapes. Engel has also integrated injection molding technology packages, such as physical foaming.

Grafen AB introduces graphene-coated textiles
The G-Heatex series uses graphene flakes to entirely impregnate textiles for uniform electrical resistance properties. It is available for a range of textile substrate types.
Grafren AB (Linköping, Sweden) has introduced G-Heatex, a series of graphene-coated textiles, which reportedly supply powerful and uniform heat while remaining soft, flexible, breathable and ultra-lightweight.
Grafren AB has recently patented two innovations, which are now covering its full production cycle. The company now has the technology for separating high-quality graphene flakes from any grade of incoming material. The access to the high-quality graphene will enable the company to work on graphene textiles.
“We invented the method to incorporate [the] smallest flakes of graphene inside of the fabric on the nanoscale level,” says Grafren’s Technical Director, Dr. Mike Zhyback. Graphene nanoparticles — or flakes — are entirely impregnated inside the fabric and coating layer by layer in every individual textile fiber. Because of the high electrical conductivity of graphene, attached flakes create a “conductive skin” on every fiber, which makes the entire fabric electrically active. Graphene can be coated on diverse textile substrates and the electrical resistance can be tailored depending on the application requirements.
Graphene textiles are said to have applications in defense, aerospace, healthcare, mobility and automotive due to the number of functions it possesses. Grafren says it is currently focused on the heating function of the fabric, as well as creating fully textile electrical heating elements to deliver uniform, homogeneous heat. The company claims that this is the only solution of its kind on the market.

FACC develops and manufactures composite structures for Ariane 6 launch vehicle
Astris kick stage main structure will be characterized by high strength and the use of ultralight carbon fiber material, with first delivery scheduled for October 2022.
In an effort to use its composites technologies to tap into end markets outside of its core aerospace business, FACC AG (Ried im Innkreis, Austria) has secured its first project under its New Space business segment, with an order from the ArianeGroup (Paris, France) to develop and manufacture the Astris kick stage main structure for the Ariane 6 family of launch vehicles.
“By awarding us a contract to participate in the Ariane 6 rocket, the ArianeGroup has placed its trust in us to help shape the new generation of European launch vehicles as a development and manufacturing partner,” notes Robert Machtlinger, CEO of FACC. “For us, space is an important future topic, which we have defined as a new business field in our 2030 corporate strategy. This is an area where we can make valuable use of our FACC composite technologies, which we have been developing for the aviation industry over the past decades. Our goal is to apply our lightweight construction expertise and state-of-the-art manufacturing facilities to provide a carbon fiber solution for the load-bearing structure of Ariane 6 kick stage that will reduce weight and enable use for commercial space transportation through efficient series production.”
The ArianeGroup is a leading enterprise in the field of space transportation. With its new launch vehicle, the company aims to offer maximum flexibility to its customers in institutional and commercial markets. Ariane 6 is a program of the European Space Agency (ESA), and is designed to provide independent access to space for a wide range of missions.
The kick stage main structure, which will be developed and produced by FACC, is the load-bearing structure of an additional optional stage which is designed to expand the Ariane 6’s mission range and make the rocket more versatile in terms of the types of payloads it could carry. The component is characterized by high strength and the use of ultralight carbon fiber materials; it carries, in addition to the actual payload, four fuel tanks, the newly developed Berta engine and state-of-the-art flight electronics into higher spheres. In addition, the use of carbon fiber for the launch vehicle’s rocket stage is also under development.
The first delivery is scheduled to arrive in Bremen, Germany, in October 2022. There, the kick stage will undergo further tests for a potential first mission, the ESA’s Hera mission, which is to demonstrate planetary asteroid defense technologies. The goal of Hera is to test the extent to which an asteroid can be deflected from its trajectory by means of two comets passing by Earth.
Overall, FACC’s contribution brings the company a step closer to looking beyond existing horizons and establishing itself as an innovator in multiple fields.

The component is characterized by high strength and the use of ultralight carbon fiber materials; it carries, in addition to the actual payload, four fuel tanks, the newly developed Berta engine and state-of-the-art flight electronics into higher spheres. In addition, the use of carbon fiber for the launch vehicle’s rocket stage is also under development.
The first delivery is scheduled to arrive in Bremen, Germany, in October 2022. There, the kick stage will undergo further tests for a potential first mission, the ESA’s Hera mission, which is to demonstrate planetary asteroid defense technologies. The goal of Hera is to test the extent to which an asteroid can be deflected from its trajectory by means of two comets passing by Earth.
Overall, FACC’s contribution brings the company a step closer to looking beyond existing horizons and establishing itself as an innovator in multiple fields.

NCC and Nexam find solution for composites use in extreme temperatures
In collaboration with Nexam Chemical, The National Composites Centre (NCC) says it has successfully manufactured a composite using a high temperature resin, providing a solution to the challenge of using advanced materials in components that need to withstand extreme temperatures.
The NCC’s interdisciplinary expertise in the fields of High Volume Manufacturing, Tooling, Design, Materials Science and Flow Simulation solved the manufacturing challenges existing at elevated temperatures and proved a composite part can be made using resin. This development paves the way for industry to take advantage of the unique qualities composites offer in elements that get very hot, such as sections of engines and the housing for electric batteries, which wasn’t previously possible.
Throughout its research, the specialist team used Nexam Chemical’s new resin system, NEXIMID. Produced in the UK, NEXIMID can operate at temperatures up to 400°C, higher than almost all other resin systems. Whilst resin transfer moulding is usually conducted at around 120°C, by developing high temperature specialist equipment – including unique tooling design and high temperature sealings – the NCC were able to keep the resin above 250°C throughout the injection process, allowing the resin’s high temperature capability to be combined with a high processing temperature for a final product that can cope with much higher temperatures than previous composites.
Throughout the process, the NCC, part of the High Value Manufacturing Catapult, has also shown that the resin system is safe, not emitting the high levels of toxic gases that other Polyimide resins can.
“Being able manufacture carbon fibre composites using a UK-produced high temperature resin system is a huge step forward in enabling industry to adopt advanced materials in components that were previously unable to take advantage of them,” said Dr David King, Advanced Research Engineer at the NCC. “The excellent thermal capability of the material expands the boundaries of composites into more demanding applications. Based on the emerging details of this expanded capability we are already working with industry customers on new applications for composite parts, and are excited to further develop our High Temperature Resin Transfer Moulding capability by collaborating closely with Nexam and other partners.”
Boyd Cushing, Business Development for Nexam Chemical UK & Ireland, added: “We are delighted that our five years of collaboration with the NCC has resulted in a major innovation breakthrough for high temperature RTM composites. We look forward to welcoming industrial partners who may have interest with our Scottish origin NEXIMID non ITAR restricted resin in aerospace and defence applications that are looking for high performance material composite parts.”
Following this successful collaboration, Nexam Chemical has joined the NCC as an SME Affiliate Member, paving the way for further projects that will aid industry in using high temperature resin transfer moulding to their advantage.
