Development of TORAYCA prepreg P2302 carbon fiber reinforced plastic for aircraft primary structural materials

Abstract
The structure of prepregs (TORAYCA Prepreg P2302) for aircraft primary structure materials consists of TORAYCA T800H, high-strength carbon fibers, and 3900-2, high toughness resin and the improvement of impact resistance was achieved while maintaining superior heat resistance of epoxy matrices. The TORAYCA Prepreg 2302 satisfies environment resistance and durability necessary as a structural material and has been accepted as an industrial material because of its superiority in prepreg handling properties which are important for actual fabrication. The P2302 is used for empenage and floor beams of the B777 by Boeing and also contributes to light-weight of primary structural materials for aircraft.
