Abstract: A method produces thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle obtained by impregnating reinforcing fibers made from continuous fibers with a thermoplastic resin, said method including: an application step in which a sheet-shaped reinforcing fiber bundle obtained by arranging reinforcing fibers made from continuous fibers in one direction is passed through an application section which retains thermoplastic resin, and the thermoplastic resin is applied to the sheet-shaped reinforcing fiber bundle to constitute a thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; a further impregnation step in which the applied thermoplastic resin is further impregnated into the inside of the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; and a shaping step in which the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle is shaped and solidified by cooling.

Abstract: A stampable sheet includes a resin and carbon fiber sheet including fiber bundles of discontinuous carbon fibers, wherein the carbon fiber sheet includes fiber bundles having a bundle width of 50 μm or greater and opened fibers ranging from fiber bundles having a bundle width less than 50 μm to fibers obtained by opening to the single-fiber level. When the direction along which the opened fibers have been oriented most is a 0° direction and the range of from the 0° to 90° direction is divided into angular zones, the distribution curve showing the proportion of the number of fiber bundles in each angular zone to that in all angular zones and the distribution curve showing the proportion of the number of opened fibers in each angular zone to that in all angular zones are reverse to each other in terms of gradient of the 0° to 90° direction.

Abstract: A spongelike structure or a powder having fibers three-dimensionally arranged therein with high dispersibility, whose apparent density can be designed depending on the purpose or utility, as well as a process producing it. A fiber dispersion in which fibers having a number mean diameter in a predetermined range are dispersed in a dispersion medium, and this fiber dispersion is dried to remove the dispersion medium, thereby, a spongelike structure and a powder are produced.

Abstract: A carbon fiber composite material which includes a carbon fiber sheet as a reinforcing material and a thermoplastic resin as a matrix resin, the carbon fiber sheet exhibiting a work per areal weight of 1×10−3 to 30×10−3 [(N·mm)/(g/m2)] in a tensile test using a specimen having a width of 25 mm. The carbon fiber composite material exhibits excellent flowability in molding and ensures excellent moldability even when molded into a complicated shape. Further, the composite material can yield a molded product which has high mechanical properties with minimized dispersion, thus being suitable for press molding.
