Abstract
Provided is a method for manufacturing a fiber reinforced plastic molded body, the method including: performing thermocompression molding, by using a molding die, on a molding precursor which is obtained by arranging a prepreg including a thermosetting resin and a fiber around a thermoplastic solid body.
Claims20
A method for manufacturing a fiber reinforced plastic molded body, the method comprising:
- performing thermocompression molding, by using a molding die, on a molding precursor,
- wherein the molding precursor is obtained by arranging a prepreg comprising a thermosetting resin and a fiber around a wax and forming a barrier layer between the prepreg and the wax, and
- wherein, in the thermocompression molding, at least a part of the wax is melted and expands, and the molten wax is suppressed by the barrier layer from leaking outside the prepreg, such that internal pressure of a core, comprising the barrier layer and the wax, increases.
