Abstract
A method of manufacturing a composite includes bringing a first surface of a first base in which a first fiber base that is to constitute the first base is impregnated with a first resin into contact with a second surface of a second base in which a second fiber base that is to constitute the second base is not impregnated with a second resin, and impregnating the second fiber base with a portion of the first resin with which the first fiber base is impregnated.
Claims8
A method of manufacturing a composite, the method comprising:
- disposing a first base on a forming die;
- disposing a second base so as to bring a first surface of the first base into contact with at least part of a second surface of the second base,
- wherein:
- the first base includes the first surface having a first fiber base impregnated with a first resin;
- and
- the second base includes the second surface having a second fiber base not impregnated with a second resin;
- and
- impregnating the second fiber base with a portion of the first resin with which the first fiber base is impregnated,
- wherein the impregnating the second fiber base with the portion of the first resin comprises:
- attaching a film to the forming die to form a hermetically sealed space that houses at least the first base and the second base between the film and the forming die;
- disposing a vacuum pump configured to suck an air and the second resin within the hermetically sealed space to an outside of the hermetically sealed space;
- maintaining the hermetically sealed space that houses at least the first base and the second base having the first surface and the second surface in contact with each other within a melting temperature range of the first resin;
- and
- driving, when the first resin is molten, the vacuum pump to impregnate the second fiber base with the portion of the first resin, and
- wherein the method further comprises, after the impregnating the second fiber base with the portion of the first resin:
- supplying, while the driving vacuum pump is kept, the second resin into the hermetically sealed space to fill the second fiber base with the second resin so that the second resin is in contact with the portion of the first resin;
- and
- executing either one of:
- heating the first base and the second base when both of the first resin and the second resin are a thermosetting resin;
- and
- cooling the first base and the second base when both of the first resin and the second resin are a thermoplastic resin.
