Abstract

A method of producing thermoplastic resin composite material in which a main base material containing thermoplastic resin and a sheet-like shaped auxiliary base material are integrally molded and are made into composite material. The production method includes the steps of: heating the auxiliary base material (step S 1 ); disposing the heated auxiliary base material in a mold (step S 2 ); disposing the main base material in the mold via the auxiliary base material (step S 3 ); closing the mold, and pressing together and integrally molding the auxiliary base material and the main base material (step S 4 ); and taking out the integrally-molded thermoplastic resin composite material from the mold.

Claims (14)

1. A production method for thermoplastic resin composite material in which a main base material containing thermoplastic resin and a sheet shaped auxiliary base material are integrally molded and are made into composite material, the production method, comprising the steps of:

heating the auxiliary base material;

disposing the heated auxiliary base material in a mold;

pressing a plurality of portions of the heated auxiliary base material disposed in the mold against the mold a plurality of times, the pressing being performed along an inner wall of a cavity of the mold, so as to tailor the heated auxiliary base material to the mold;

after pressing the plurality of portions of the heated auxiliary base material disposed in the mold against the mold the plurality of times, disposing the main base material in the mold on the heated auxiliary base material;

closing the mold, and pressing together and integrally molding the heated auxiliary base material and the main base material; and

taking out the integrally-molded thermoplastic resin composite material from the mold,

wherein the step of pressing the plurality of portions of the heated auxiliary base material disposed in the mold against the mold the plurality of times, so as to tailor the auxiliary base material to the mold, is performed using a press mechanism comprising a rod member and actuator configured to move the rod member.

2. The production method for thermoplastic resin composite material according to claim 1 ,

wherein, after the step of heating the auxiliary base material, the heated auxiliary base material is disposed in the mold while the heated auxiliary base material is kept warm.

3. The production method for thermoplastic resin composite material according to claim 1 ,

wherein the main base material contains the thermoplastic resin in which carbon fiber of a prescribed length is contained in a dispersed state.

4. The production method for thermoplastic resin composite material according to claim 2 ,

wherein the main base material contains the thermoplastic resin in which carbon fiber of a prescribed length is contained in a dispersed state.
