SEMI-IMPREGNATED PREPREG AND MOLDING METHOD USING THIS PREPREG

摘要

PROBLEM TO BE SOLVED: To provide a prepreg from which a molded product free from residual air and reduced in voids is manufactured, and a manufacturing method using this prepreg. SOLUTION: This semi-impregnated prepreg 1 is composed of a thermosetting resin film 5 and fiber-reinforcing materials 2 and 3 laminated on at least one side of the film 5 and has a projecting fibrous part 9 formed on at least a part of the peripheral end part S of the semi-impregnated prepreg 1. The thermosetting resin film 5 may use a carrier. The prepreg is best-suited for use in vacuum bag molding and autoclave molding processes. COPYRIGHT: (C)2004,JPO
