  • Patent number: 11951728
    Abstract: A fiber-reinforced plastic molded body includes: a laminated body having a configuration of laminating a sandwich structure member obtained by laminating one layer or two or more layers of a unidirectional fiber-reinforced resin constituted from a unidirectional continuous fiber and a matrix resin on both surfaces of a core layer and one layer or two or more layers of a woven fiber-reinforced resin constituted from a woven fiber and a matrix resin such that the one layer or two or more layers of a woven fiber-reinforced resin are disposed on the design surface side of the unidirectional fiber-reinforced resin; and the resin member is not substantially exposed in a projection plane from the woven fiber-reinforced resin side.

  • Patent number: 8641939
    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 ?m and the mean fiber diameter of the carbon short fibers is 5 to 20 ?m. 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.

  • Patent number: 7410719
    Abstract: A porous carbon base material includes a sheet containing carbon short fibers dispersed randomly and a carbonized resin, in which the carbon short fibers are bound by the carbonized resin and the volume of pores having a pore diameter of 10 ?m or less is 0.05 to 0.16 cc/g. A method for producing this porous carbon base material includes intermittently transporting a precursor fiber sheet including short carbon fibers dispersed randomly and a resin 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.
