This product supports applications in gearbox, suspension, pylons, wings, and crash structures to name but a few,” states Graham Roberts, F1 Business Development Manager.

Toray TC346 was designed with ease of production in mind. Excellent out life and storage life, flexible cure cycles, and good handling/tack/drape characteristics will make this product a fast first choice in the market.
