Fiber-reinforced composite structural element and method of manufacturing the same

摘要

A box-shaped fibrous preform is produced by laying or superposing a plurality of reinforcing fibrous material layers (6a) on top of each other into a box-like shape. The box-shaped fibrous preform is used as an auxiliary member (1) or by cutting the box-like member into segments of a required shape. The auxiliary member (1) is combined with reinforcing fibrous material forming a main structural member(21; 31; 53; 63). The auxiliary member and the main structural member are placed in a mold and a resin is supplied into the mold to carry out a resin-impregnating and curing operation.
