From the Sector

Toray Industries, Inc. announced the successful development of recycled carbon fiber (rCF) derived from the production process of the Boeing 787 components using Toray’s advanced carbon fiber, TORAYCA™. The rCF, which is based on pyrolysis recycling process, has been integrated into the Lenovo ThinkPad X1 Carbon Gen 12 as reinforcement filler for thermoplastic pellets. Toray and Lenovo will continue to collaborate to expand the usage of rCF in other Lenovo products.

Toray rCF is the outcome of Boeing and Lenovo’s shared commitment to minimize their environmental impact. Boeing’s objective is to reduce solid waste going to landfill and produce recyclable materials, while Lenovo has been exploring materials to reduce the carbon footprint of their products. Toray rCF connects these visions by repurposing Toray’s high-performance carbon fiber from the Boeing aircraft production process into Lenovo’s ultra-light laptop PC.

TORAYCA™ is an established aerospace material known for its high strength, stiffness, and lightweighting properties. These qualities have led to its adoption in other applications such as electrical and electronic equipment housings, sports equipment, and other industrial applications.

A key advantage of carbon fiber is the ability to retain its primary mechanical properties even after the recycling process. Toray is actively advancing recycling technologies and establishing a strategic business model for rCF. Given that the carbon footprint of rCF is lower than that of virgin carbon fiber, Toray is proactively recommending the adoption of rCF to reduce the environmental impact of customers’ products. This commitment aligns with Toray’s dedication to fostering a circular economy, thereby reducing landfill waste.

Recreational boaters now have an easy way to be more sustainable following the introduction of a new biocide-free (B-Free) fouling control range from AkzoNobel’s Yacht Coatings business.

The first product to be launched from the new B-Free range is B-Free Explore. It features a specially-developed, unique silicone polymer technology which produces an exceptionally smooth and slick hull – helping to reduce drag.

Fouling is controlled by preventing microorganisms such as barnacles, slime and algae from forming strong bonds with the hull of the boat. Any that do adhere can be simply wiped away by hand or water jet.

“We’ve developed high-performance technology which allows boaters to maintain a clean, smooth hull,” explains Simon Parker, Director of AkzoNobel’s Marine and Protective Coatings business. “It’s based on proven technology and exemplifies the restless spirit of innovation which has been the cornerstone of our International brand for more than 140 years.”

Adds Jemma Lampkin, Global Commercial Director for AkzoNobel’s Yacht Coatings business: “Boaters are becoming more aware of the impact they can have on the environment, but they still require technologies that deliver high-performance fouling control. B-Free Explore provides a stand-out solution for both of these challenges.”

Specially crafted for the leisure boat market, B-Free Explore is the culmination of a five-year development program. It can be applied to new hulls or directly to existing antifouling, without the need for the removal of the previous antifouling coating. This makes it simple for boaters to upgrade from their traditional coatings to the new technology.

The new product is also better for the marine ecosystem. Being biocide-free, it provides a smooth surface for improved hull efficiencies, which can lead to a reduced carbon footprint.

Currently being introduced in Northern Europe, B-Free Explore will be rolled out across Germany, the Netherlands, Norway and Sweden in January 2023.

Notus Composites (UAE), the award-winning producer of epoxy prepreg materials, announces the latest addition to its high-performance epoxy range with the launch of its new NE7 low temperature curing prepreg system. The Notus NE7 formulation allows composite manufacturers to cure components at temperatures as low as 70˚C, reducing energy consumption and enabling more cost-effective tooling options.

Notus Composites has developed the new NE7 prepreg systems for applications across the Marine, Architecture, Industrial and Wind Energy sectors, with the novel low temperature curing chemistry delivery significant cost benefits. Existing prepreg manufacturers can now use more cost-effective composite tooling, with new prepreg users able to switch easily from existing infusion or wet laminating processes without creating expensive new high temperature tooling.

NE7 prepregs can be cured at temperatures as low as 70˚C, with the standard cure cycle being 12 hours at 70˚C, matching the typical cycle time for an infused part with a component Tg of 85˚C. NE7 materials have a good outlife of 30 days at 20˚C and are available in all prepreg and Notus single sided N1-Preg formats with unidirectional, multiaxial, and woven reinforcements. NE7 can also be supplied as a resin film.

Notus has recently supplied NE7 low temperature prepregs to Dubai based Aeolos Composites for the production of their new Aeolos P30 racing yacht. The P30 is a futuristic new craft created by top German sailor and designer, Hans Genthe, with a super light carbon fibre construction and large sail area that promises spectacular on the water performance for a thirty foot yacht. Notus delivered a range NE7 prepregs for the build, including woven, multiaxial, and unidirectional carbon fibre reinforcements as well as adhesive films for core bonding.

Teijin Carbon Europe introduces a new thermoplastic carbon fiber tape (TPUD) based on PPS. The new Tenax™ TPUD with PPS matrix allows entry in new cost-sensitive markets while offering the typical TPUD advantages like high resistance to chemicals and solvents, low flammability, storage or shipping at room temperature and recyclability.  

Due to its flame retardant properties and low smoke emission, it can be used in interior applications of aircraft or rail vehicles, among others. The maximum continuous operating temperature is up to 220 °C. Very low water absorption, excellent creep resistance even at elevated temperatures and high dimensional stability round off the property portfolio of this new TPUD. It is therefore also suitable for demanding applications in the aerospace, oil & gas, sporting goods or industrial sectors, while remaining cost-effective. These properties make the product perfect for highly automated processing routes such as ATL or AFP in combination with overmolding for complex geometries. Production start for the Tenax™ TPUD with PPS matrix is the first quarter in 2021.

For almost 10 years, unidirectional tapes (TPUD) have been manufactured from carbon fibers and thermoplastics in Heinsberg, Germany. The semi-finished products have so far been offered with PEEK or PAEK – and PPS is now added to the list of available matrixes. PPS allows a lower process temperature compared to PEEK or PAEK. For the industrial market in particular, increasing the production rate to make processes more cost-efficient is an opportunity.

With their recently installed high-temperature unidirectional tape line, Japan-based composites manufacturer MaruHachi enables new opportunities for high-end applications in demanding market segments like aerospace, automotive or others outperforming traditional materials based on PP and PA which are already widely available.

In the first phase, MaruHachi will produce up to 40 tons/year and focuses now specifically on high-temperature thermoplastic uni-directional (UD) tapes and multi-layer sheet laminates. The material is based on high-performance fibers like carbon, aramid, glass or natural fibers and the matrix can be high-performance polymers like PPS, PEEK or other higher temperature polymers, which are much tougher than epoxies and easy to recycle. With a width of 500 mm, a specific weight from 60 to 350 g/m2, depending on the chosen material, the lines can operate under temperatures up to 420 degrees Celsius. Working under these extremely high temperatures allows for better material properties of the final application, higher performance, increased resistance and integrated high-performance functionalities e.g. by overmoulding.

Since 2017, MaruHachi Group is active in the European market in cooperation with Dr. Michael Effing,the CEO of AMAC GmbH, who advises and supports the company strategically. The established, family-owned MaruHachi Group has a strong history in automotive and medical textiles and has been active in the innovative composites market for more than 15 years.

Toshi Sugahara, CEO of MaruHachi: “For many years, we have already been cooperating with domestic and international partners on high-demand applications and therefore, MaruHachi decided now to invest over 1 million EUR in this new line in phase 1, including a funding participation from the Japanese government NEDO. New developments in phase 2 will be be undertaken by end of 2021 on the downstream technologies like the automated preforming and consolidation. With our new products, we want to contribute to significant weight reductions of the final products, thus improve energy efficiency while offering a cost-efficient and high-quality solution.”

Dr. Effing, CEO of AMAC GmbH confirms: „The focus on the niche of high-temperature products based on PPS and PEEK allows MaruHachi on very demanding high-end applications such as structural frames on space and aircrafts, aircraft seats or engine components etc. The tapes are fully recyclable and can be processed e.g. with high-speed with laser-based tape placement machines and robots.”

STAMFORD – German ultralight aircraft specialist Flight Design has chosen Hexcel as its key supplier adopting low-temperature curing prepreg into its aircraft production. Hexcel’s HexPly® M79 Carbon Fiber prepregs deliver a more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight Design has always relied heavily on composites for its aircrafts’ ultralight construction and turned to long-term composite materials partner Lange + Ritter, part of Hexcel’s European distribution network, when they began searching for a prepreg material solution. Hexcel and Lange + Ritter created several new product codes specifically for Flight Design and then supplied materials for initial handling trials and prototyping. Hexcel’s HexPly M79 low temperature curing out of autoclave solution was first used in the new F2 prototype. As part of its material supply package, Lange + Ritter also sent a team for on-site training and technical support, allowing the Flight Design production team to get up to speed with prepreg as quickly as possible.

HexPly M79 prepregs can be cured at temperatures as low as 70˚C for eight hours or 80˚C for four hours, reducing tooling costs and increasing build rates. When combined with Hexcel’s innovative air venting Grid Technology, HexPly M79 UD carbon tapes can also be laminated with reduced debulking steps to produce void contents <1% irrespective of laminate thickness. With consistently low void contents and improved mechanical properties, designers and engineers are able to further optimize highly loaded composite aerostructures.

As more and more of its composite aircraft parts are transferred to prepreg technology, Flight Design is seeing the benefits of its switch to HexPly M79. Lay-up is cleaner and more precise, low temperature oven curing is quick and energy efficient, and the manufacturing process consistently outputs exceptionally high-quality laminates and components. The long-term strategy is to integrate HexPly M79 across the range, with Hexcel materials lightening the ultralight aircraft at Flight Design even further.

“The materials and technology package from Hexcel and Lange + Ritter has been a big success for us at Flight Design,” comments Daniel Gunther, Managing Director at Flight Design. “When we took the decision to switch to prepreg, we looked at many options but only Hexcel and Lange + Ritter could offer us low temperature out-of-autoclave (OOA) curing, globally respected material quality and the customer service levels we were searching for.”
