PROBLEM TO BE SOLVED: To provide a method for manufacturing a fiber-reinforced polypropylene resin foam molded body for obtaining an injection foam body having weight saving by forming, high in shock resistance in normal temperature and low temperature atmosphere, small in reduction of rigidity at high temperature compared to rigidity at normal temperature, small in change of maximum flexural power with maintaining a sheet thickness because efficient forming ratio is achievable and less in appearance deterioration.SOLUTION: There is provided a manufacturing method of a fiber reinforced polypropylene resin foam molded body including a melting process for adding a chemical foaming agent (i) to a specific fiber reinforced polypropylene resin for foam molding and melting them (A), a specific injection process (B) and a specific foaming process (C). |
