From the Sector

British technology company Hypetex has been awarded a significant grant from Innovate UK to develop the world’s first technical coloured flax fibre, which will have applications in the sustainable manufacturing of cars, boats and other products that are usually made with carbon fibre.

Called FlaxTex the material is strong, lightweight and 100 per cent biodegradable, having a net positive carbon footprint at point of manufacturing. It can be colourised whilst enhancing its performance properties, with the process adding some important manufacturing attributes compared to standard flax fibre.

As such, FlaxTex’s mechanical properties represent the closest sustainable substitute for robust and lightweight materials like glass fibre and carbon fibre in composite structures.  

The performance of standard flax fibre is often hindered by its high moisture absorption, resulting in reduced structural integrity when used in composite construction. In addition, the natural brown colour of flax has been deemed unappealing for product use.

Flaxtex solves these issues by removing moisture through the colouring process and sealing the fibres, which waterproofs them and enabling their core mechanical properties. Hypetex’s patented nano-pigment technology changes the colour adding an aesthetic quality to the material.  

This colouring process is set to transform industrial design possibilities of Flax natural fibres by enhancing the strength and performance while simultaneously reducing post-processing requirements and total energy usage. This also aligns with Hypetex's commitment to supporting the green transition and helping manufacturers meet government expectations on the path to UK Net Zero targets and the European Green Deal.

Over the course of a 12-month industrial research project, Hypetex will further optimize its resin systems and processes, expanding the use of FlaxTex across various markets.  

FlaxTex has a range of industry uses, including on construction, automotive, sports equipment and furniture products.

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.
