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: Provided are: a fiber-reinforced prepreg having a thermosetting resin as a matrix, wherein part of the fiber-reinforced prepreg is a low-adhesion region that has been treated to reduce adhesiveness, and the resin reaction rate of the low-adhesion region is preferably 0.1-20%; a tape and a wound body obtained from the fiber-reinforced prepreg; and a method for producing the fiber-reinforced prepreg and fiber-reinforced prepreg tape. This makes it possible to provide a fiber-reinforced tape of which the adhesiveness is appropriately lowered to enable suitable application to AFP conveyance while using a simple technique.
