Abstract
A method of producing a fiber-reinforced plastic includes disposing a transparent film as an outermost layer on a lower die of a molding die, disposing a base sheet formed of a fiber fabric on the transparent film, closing the molding die with an upper die, and injecting a matrix resin into the molding die closed. The transparent film has grooves on a surface facing the base sheet. In the disposing, the base sheet is disposed such that the grooves are located between adjacent weaving gaps of the base sheet.
Claims8
A method of producing a fiber-reinforced plastic, the method comprising:
- disposing a transparent film as an outermost layer on a lower die of a molding die and disposing a base sheet formed of a fiber fabric on the transparent film;
- and
- closing the molding die with an upper die and injecting a matrix resin into the molding die closed, wherein
- the transparent film has grooves on a surface facing the base sheet, and
- the base sheet is disposed in the disposing such that the grooves are located between adjacent weaving gaps of the base sheet.
A fiber-reinforced plastic comprising:
- a fiber-reinforced plastic layer that comprises a base sheet formed of a fiber fabric as a front layer and is impregnated with a matrix resin;
- and
- a transparent film as an outermost layer that covers the front layer of the fiber-reinforced plastic layer and is integrally molded with the fiber-reinforced plastic layer, wherein
- the transparent film has grooves on a surface facing the base sheet, and
- the grooves are located at least between adjacent weaving gaps of the base sheet and the matrix resin fills the grooves.
