Abstract: A carbon-fiber-reinforced plastic molded article which is made of an at least two-layer laminate including one or more unidirectionally continuous-carbon-fiber-reinforced sheets wherein continuous carbon fiber bundles are arranged in one prescribed direction, characterized in that, when the carbon fibers at the design surface of the molded article are observed, the design surface being constituted of the outermost unidirectionally continuous-carbon-fiber-reinforced sheet, the area fraction of regions where the proportion of carbon fibers which are inclined at angles of 3° or more to the one prescribed direction is 0.5% or more is at most 20% relative to the whole area of the design surface. Thus, the present invention can provide a molded article in which carbon fibers are uniformly arranged at the design surface and which has excellent appearance design.

Abstract: A nonwoven fabric comprising a flame-retardant acrylic fiber, characterized in that it has a weight per square-meter of 70 to 190 g/m2, a thickness of 0.1 to 0.3 mm, a density of 0.35 to 0.8 g/cm3; and a nonwoven fabric comprising a carbon fiber, characterized in that it has a weight per square-meter of 50 t o 150 g/m2, a thickness of 0.1 to 0.25 mm, a density of 0.3 to 0.7 g/m3, a surface roughness Ra of 30 .mu.m or less, a tensile strength of 0.2 kgf/cm o r more, and a maximum fracture radius being defined in the specification of 20 mm or less. Said carbon fiber nonwoven fabric is produced by subjecting the above flame-retardant acrylic fiber to a carbonization treatment and can be suitably used as a material for forming an electrode of a fuel cell.

Abstract: A porous carbon sheet obtained by binding separate carbon short fibers with a carbonization product of a resin, wherein the pore mode diameter of the sheet is 45 to 90 µm and the mean fiber diameter of the carbon short fibers is 5 to 20 µm. The sheet can be produced by thermoforming a precursor fiber sheet comprising carbon short fibers of 15 to 30 g/m2 in basis weight and a thermosetting resin of 30 to 80 g/m2 in basis weight by hot plates having a certain clearance and carbonizing the thermosetting resin contained in thermoformed precursor fiber sheet.

Abstract: A porous carbon base material, which comprises a sheet containing carbon short fibers dispersed randomly and a carbonized resin, wherein the carbon short fibers are bound by the carbonized resin and the volume of pores having a pore diameter of 10 µm or less is 0.05 to 0.16 cc/g; and a method for producing the porous carbon base material, which comprises transporting a precursor fiber sheet comprising carbon short fibers dispersed randomly and a resin intermittently to a space between heated plates, subjecting the precursor to a heating and pressuring treatment by the heated plates while the transformation stops, carrying out the transportation of the sheet after the treatment, and then carrying out a heat treatment, to thereby carbonize the resin in the sheet.
