The product supports applications such as gearboxes, suspensions, hangers, wings and anti-collision structures. "
Toray TC346 is designed with ease of production in mind. Good service life and storage life, flexible curing cycle and good handling / stickiness / drape characteristics will make this product a quick first choice on the market. TC346 can be made into unidirectional tape or fabric of various weights and fibers.
