methods of fabricating composite material element, aircraft wing structure and aircraft fuselage structure, and prepreg sheet laminate.

摘要

A manufacturing method of composite material member includes a step of shaping a laminate including laminated prepreg sheets along a mold. The laminate includes a first layer in which fibers are oriented in single direction. In the first layer, a first surface crossing the single direction and a second surface crossing the single direction are confronted each other such that the first surface and the second surface face each other. Since the fibers are discontinuous between the first surface and the second surface, the laminate is easily shaped and wrinkles are hard to be generated in a composite material member to be manufactured from the laminate.
