Abstract:
Provided is a molding material comprising a composite of 1 to 50 wt % of a continuous reinforcing fiber bundle (A) and 0.1 to 20 wt % of a poly (phenylene ether ether ketone) oligomer (B); and 30 to 98.9 wt % of a thermoplastic resin (C) adhering to the composite, wherein the component (B) has a melting point of not higher than 270° C. Also provided are a method for molding the molding material, a method for producing the molding material, and a method for producing a fiber-reinforced composite material.A molded article having high heat resistance and dynamic properties can be easily produced without impairing the economic efficiency and productivity during the process for producing a molding material. In addition, a fiber-reinforced composite material can be produced with more ease and high productivity.
