Abstract
In order to prevent positional displacement of a graphite sheet laminate during production of a resin molded product obtained by integrally molding the graphite sheet laminate and a resin, the present invention uses a graphite sheet laminate having a structure in which a first fixing layer having a modulus of elasticity of not less than 7.0×104 Pa and not more than 5.0×107 Pa at 250° C. is in contact with a graphite sheet on at least one of principal surfaces of the graphite sheet.
Claims20
A method for producing a resin molded product, comprising the steps of:
- providing, along a cavity surface of one of injection molding molds, a graphite sheet laminate having a structure in which a first fixing layer having a modulus of elasticity of not less than 7.0×104 Pa and not more than 5.0×107 Pa at an introduced resin temperature during injection molding is in contact with a graphite sheet on at least one of principal surfaces of the graphite sheet, the graphite sheet laminate being provided so that a principal surface of the graphite sheet laminate which principal surface is opposite from the first fixing layer side principal surface of the graphite sheet laminate is in contact with the cavity surface;
- clamping the injection molding molds together;
- and
- injecting a resin in a molten state into a cavity so as to cause adhesion of the graphite sheet laminate and the resin.
