THERMOPLASTIC RESIN-BASED FIBER-REINFORCED COMPOSITE MATERIAL FOR PRESS MOLDING AND METHOD FOR PRODUCING THE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin-based fiber-reinforced composite material for press molding, on which is disposed precisely tape-shaped article which comprises a thermoplastic resin-based discontinuous fiber-reinforced composite material, a continuous reinforcing fiber and a thermoplastic resin and to provide a method for producing the material.SOLUTION: The tape-shaped article (2) comprising the continuous reinforcing fiber and the thermoplastic resin is welded/fixed partially onto at least a portion of the surface of a plate-like thermoplastic resin-based discontinuous fiber-reinforced composite material (1) comprising a discontinuous fiber and the thermoplastic resin by melting at least one of :the thermoplastic resin contained in the plate-like thermoplastic resin-based discontinuous fiber-reinforced composite material (1) comprising the discontinuous fiber and the thermoplastic resin; and the resin contained in the tape-shaped article (2) comprising the continuous reinforcing fiber and the thermoplastic resin. Thereafter, the whole of the thermoplastic resin-based discontinuous fiber-reinforced composite material (1) and the tape-shaped article (2) is hot-pressed to obtain a planar integrated product. Subsequently, the planar integrated product is press-molded to obtain a molded article having a desired shape.
