Abstract:
A composite molding material comprises a thermoplastic resin and reinforcing materials. The reinforcing materials are selected from a glass wool having an average fiber diameter of 1-7 μm and a pre-kneading fiber length of 300-1000 μm and a fibrous reinforcing material having an average fiber diameter of 7-20 μm. The glass wool and the fibrous reinforcing material are dispersed in the thermoplastic resin.
