Title:

THERMOSETTING PREPREG COMPOSITION AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2000/058390

Kind Code:

A1

Abstract:

A thermosetting prepreg composition obtained by photopolymerizing a composition comprising at least one polymerizable unsaturated compound comprising an unsaturated polyester resin and/or a vinyl ester resin, a fiber reinforcement and/or a filler, a photopolymerization initiator, and a thermal polymerization initiator to precure the composition to such a degree that part of the radical-polymerizable unsaturated compound remains unreacted. The B-stage state of the thermosetting resin can be easily regulated, and a constant B-stage state can be realized.
