Document Type and Number:
Japanese Patent JP5717928
Kind Code:
B2
Abstract:
Disclosed is a method for manufacturing a composite material, which includes performing press molding of a fiber matrix structure including reinforcing fibers and a matrix resin mainly including a polyester-based resin having a crystallization temperature of 185°C or lower. Furthermore, the polyester-based resin is preferably a polyester-based copolymer. In addition, it is preferred that the matrix resin includes a carbodiimide, and that the carbodiimide has a cyclic structure. Moreover, it is preferred that the press molding is cold pressing in which a die temperature is 170°C or lower; that the reinforcing fibers are carbon fibers; and that the discontinuous fibers are randomly oriented in the structure.
