Method for manufacturing product made of fiber-reinforced resin and product manufactured by method.

摘要

Fibers consisting of two or more kinds of fibers in the form of roving, tape, yarn, monofilament or cloth are preformed by winding them around the core by filament winding method and is then set in the cavity of the mold so that resin impregnates the preformed fibers by reaction injection molding method. In this manner, a product made of fiber-reinforced resin and having a predetermined configuration can be obtained. If necessary, the preformed fibers are bent and then set in the cavity of the mold. It is preferable that two or more kinds of fibers are wound around the core. The fibers are dipped in liquid or a binder which does not hinder the polymerization of an unreacted monomer to be used in reaction injection molding before they are wound around the core. <IMAGE> <IMAGE>
