    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 process for producing a fiber reinforced resin which comprises placing at least a reinforcing fiber substrate in a cavity of a mold, injecting a resin into the cavity, and curing the resin, characterized in that a substrate for forming a skin layer, and a resin distribution medium, which is located between the substrate for forming the skin layer and the reinforcing fiber substrate and in which the ratio of the coefficient of impregnation thereof to that of the substrate for forming the skin layer is 1.5-10, are disposed on at least one surface of the reinforcing fiber substrate via an interlayer having a cover factor of 90%-100% and comprising at least one woven fabric. The process diminishes pinhole generation in the skin layer in RTM, and can reduce the necessity of a repair step in, e.g., a painting step as a later step, thereby improving productivity .

    Abstract: An object is to provide a manufacturing method of a fiber-reinforced resin that significantly reduces a resin filling defect on the surface and surface irregularity caused by a temperature difference between a molding temperature (curing temperature) and ordinary temperature in the course of molding the fiber-reinforced resin, and a product manufactured by the manufacturing method. There is accordingly provided a manufacturing method of a coated fiber-reinforced resin molded article and a product manufactured by the manufacturing method. The manufacturing method comprises a first molding process that cures a matrix resin which a reinforcing fiber is impregnated with at a temperature T1(°C) to obtain a fiber-reinforced resin molded article; and a second molding process that places the fiber-reinforced resin molded article in a cavity of a mold, sets the cavity to a temperature T2(°C) that is lower than the temperature T1(°C), injects a liquid coating layer-forming resin material into the cavity such as to coat at least part of a surface layer of the fiber-reinforced resin molded article, and cures the coating layer-forming resin material at the temperature T2(°C), so as to obtain the coated fiber-reinforced resin molded article, wherein the mold is comprised of at least two pieces and has the cavity in a shape that is approximately same as a shape of the fiber-reinforced resin molded article.
