MANUFACTURING METHOD FOR COMPOSITE MATERIAL

摘要

A manufacturing method for a composite material in which a fiber matrix structure comprising reinforcing fibers and a matrix resin having a polyester resin that has a crystallization temperature of 185°C or below as the main component thereof is subjected to press molding. It is preferable for the polyester resin to be a polyester copolymer. In addition, it is preferable for the matrix resin to contain a carbodiimide, and for the carbodiimide to have a cyclic structure. Furthermore, it is preferable for the press molding to be a cold press process at a mold temperature of 170°C or below, for the reinforcing fibers to be carbon fibers, and for the discontinuous fibers within the structure to be randomly oriented.
