Toray Advanced Composites’ Toray TC346 prepreg resin system for high-end motorsports has passed the SFI 56.1 and UL94 V0 flame-retardancy tests. The passing of these stringent flame-retardancy tests means Toray TC346 system satisfies the rigorous demands of the Formula One, NASCAR, and other high performance automotive and motorsport markets.

The Toray TC346 resin system is a high-temperature epoxy system developed with input from leading motorsport and automotive industry professionals. Toray engineered the material to handle a wide range of exceptionally demanding motorsport applications, such as gearbox and suspension components, which require a high service temperature and high toughness.

“We are extremely pleased that the TC346 resin system received these important flame-retardancy certifications. The distinction positions the TC346 system as the ‘go-to’ composite material that can help high-performance motorsports programmes attain significant performance improvements,” says Steven Mead, managing director of Toray Advanced Composites. Mead notes that Toray produces the prepreg at its operations in the UK and US, which will enhance the company’s support of the motorsport market in those regions.

Toray’s TC346 has excellent compression strength, interlaminar shear strength, in-plane shear modulus, and improved elevated temperature tensile strength. The TC346 system offers a superior surface finish for aesthetic appeal and controlled flow of the resin to simplify lay-up and curing production. Other motorsport component applications that require lightweighting with superior toughness would also benefit from the inherent properties of TC346. Additionally, applications that require high glass transition temperatures, excellent compression strength, and high fracture toughness could also benefit from this super-tough and flame-resistant epoxy prepreg system. TC346 is available in a wide variety of uni-directional tapes and fabric styles.
