Torayca M46X carbon fibre – better for blanks and environment

The latest carbon fibre material from Japanese manufacturing expert Toray – Torayca MX64 – is said to offer higher-strength, lower weight rods as well as being kinder to the environment.

The new offering is around 20 per cent stronger than others in the Torayca MX series while maintaining a high tensile modulus. So it reduces the weight of carbon fibre-reinforced plastic materials, lowering their environmental impact.

Typically, there is a trade-off between the tensile modulus and strength of carbon fibre. Boosting the strength while maintaining the modulus of carbon fibres with a tensile modulus exceeding 350 GPa presents technological challenges.

However, the sporting and leisure goods market demands both qualities to maintain performance while using less carbon fibre to lower the weight of moulded parts.

Toray developed M46X by pushing the structural control technology envelope. Nano-level controls of the graphite crystallite structure inside fibres resulted in an ultrafine, ultrahigh orientation producing carbon fibre that is more than 20 per cent stronger than conventional materials while maintaining its tensile modulus.

The company will also deploy Torayca M46X prepreg, with the resin matrix utilising the proprietary NanoAlloy microstructure control technology.

The new product will significantly enhance compressive strength to boost stiffness while retaining strength, reducing the weight of finished products and broadening design flexibility.

Developing high-performance carbon fibres with a high tensile modulus exceeding 350 GPa began with Torayca M40 with graphitised yarn, followed by M40J in 1984 and M46J in 1986 in response to robust demand for the high-modulus Torayca MJ carbon fibre series.

The MX series was created by applying technologies to control graphite crystallite structures and orientations inside fibres.

The first offering in this series was M40X, launched in 2018, which quickly earned a solid reputation as a high-performance carbon fibre and prepreg (a resin-impregnated intermediate base material) matching market requirements.

In line with its corporate philosophy of contributing to society by creating new value, Toray will continue developing new products that help transform the economy through the enhanced performance and processability of Torayca carbon fibre and prepreg.
