Title:
PRODUCTION OF PREPREG AND LAMINATE
Document Type and Number:
Japanese Patent JP3373164
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a good laminate not causing air pollution, capable of saving resources and having a stable quality at a low cost.
SOLUTION: This method for producing a prepreg comprises adding and homogeneously mixing a finely powdery additive having an average primary particle diameter of 0.01-1 μm to a powdery thermosetting resin composition obtained by homogeneously mixing a thermoplastic resin and a curing agent as essential components and subsequently allowing the obtained powdery resin composition 2 to exist on at least the surface of a sheet-like fibrous substrate 1. The method for producing a laminate comprises laminating one or more of the prepregs and subsequently heating and pressing the laminated prepregs.
