Claim 7:
8. A method of manufacturing a vehicle interior and exterior member,
The vehicle interior and exterior member comprising:
a fiber molded body and a synthetic resin member affixed to a surface of the fiber molded body,
wherein the fiber molded body has a first fiber layer including a first thermoplastic synthetic resin, as a base material layer, a second fiber layer including a second thermoplastic synthetic resin on one of the first fiber layer surfaces to form a fiber laminated body, the first and the second thermoplastic synthetic resins are different,
wherein the fiber molded body is formed by molding the fiber laminated body into a three-dimensional face shape,
wherein the synthetic resin member comprises a foaming agent,
wherein the synthetic resin member has a fixed portion which is fixed to the fiber molded body by solidifying in a state that where molten synthetic resin seeps into a part of the first fiber layer of the fiber laminated body that faces the synthetic resin member, and
wherein the synthetic resin member is solidified in a state where the synthetic resin member includes gas bubbles therein;
the method comprising the steps of:
heating the fiber laminated body, the fiber laminated body comprising the first fiber layer and the second fiber layer covering the first fiber layer, to soften the fiber laminated body;
press molding the softened fiber laminated body using a press mold;
cooling and pressurizing the fiber laminated body in the press mold to form a fiber molded body; and
injection molding molten synthetic resin toward the first fiber layer of the fiber laminated body while the fiber laminated body is in the press mold,
wherein the foaming agent is configured to form gas bubbles in the molten synthetic resin.
