    Abstract: A prepreg is formed by impregnating reinforcing fibers with a heat-curable resin with a cure degree greater than or equal to 3% and less than 50%, chopped prepreg obtained by cutting the prepreg is dispersed in a flat shape, and the chopped prepreg is thermally bonded together to form a fiber reinforced resin sheet. The fiber reinforced resin sheet can be used in press molding, has excellent uniformity of basis weight as a molding material allowing dense filling into a mold, and enables obtaining a molded product that has excellent mechanical characteristics thanks to increased volume content of the reinforcing fibers.

    Abstract: Disclosed is a layered carbon-fiber product obtained by superposing one or more sheets of carbon-fiber fabric each obtained using one or more carbon-fiber bundles each comprising a plurality of paralleled carbon fibers. The layered carbon-fiber product is characterized in that at least some of the surfaces and/or edge faces of the layered carbon-fiber product is constituted of a graphitized part and that the graphitized part gives a Raman spectrum in which the intensity ratio of the D band to the G band (D-band intensity/G-band intensity) is 0.3 or less. Also provided are a preform obtained using the layered carbon-fiber product and processes for producing the layered carbon-fiber product and the preform. The edge faces of the layered carbon-fiber product or preform can be easily processed, and it is possible to highly accurately trim the layered carbon-fiber product or preform while preventing the carbon fibers from fraying at the edge faces. Consequently, the layered carbon-fiber product and the preform can be easily and accurately disposed in a mold and deburring can be omitted, making it possible to attain a cost reduction and a reduction in production time.

    Abstract: A method for manufacturing fiber-reinforced plastic, in which a preform, which is made of a reinforcing fiber substrate and which has a three-dimensional shape, and an inner mold capable of being moved in a lateral direction different from the vertical direction, are disposed in a cavity formed by an upper mold and a lower mold; the plate thickness of the preform is made greater than the thickness of the molded item to be obtained; a matrix resin is injected and impregnated into the preform, then the upper mold and/or the lower mold is moved toward the other and the inner mold is moved in the lateral direction, and the preform is compressed whereby the thickness of the preform is controlled so as to reach the predetermined product thickness; and heat is then applied to harden the matrix resin and obtain the molded item. In addition, a device for manufacturing a fiber-reinforced plastic used in the manufacturing method.
