METHOD FOR PRODUCING COMPOSITE MATERIAL

Title:

METHOD FOR PRODUCING COMPOSITE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2014/184969

Kind Code:

A1

Abstract:

This method for producing a composite material involves press-molding a matrix resin containing an aromatic polycarbonate resin and having a polyester-based resin as the principal component thereof, and a fiber matrix structure comprising reinforcing fibers. In addition, it is preferable for the polyester-based resin to be a polyester-based copolymer, and to contain a terephthalic acid component and an isophthalic acid component. It is also preferable for: the mold temperature during the press molding to be a cold-press at 170°C or less; the reinforcing fibers to be carbon fibers and principally comprise non-continuous fibers; and the non-continuous fibers in the structure to be oriented randomly.
