  • Patent number: 7981500
    Abstract: There are provided a carbon fiber reinforced prepreg of gas barrier properties comprising a sheet-like carbon fiber reinforcement and a matrix resin including therein a gas barrier layer having a clay mineral with a plate-like crystal structure unidirectionally aligned and densely laminated, and a carbon fiber reinforced plastic produced from the carbon fiber reinforced prepreg. Such prepreg is obtained by disposing a film material of gas barrier properties having a clay mineral with a plate-like crystal structure unidirectionally aligned and densely laminated, in at least one interlayer of a laminate of a carbon fiber reinforced prepreg comprising a sheet form carbon fiber reinforcement and a matrix resin; and then heating and/or pressurizing the laminate. The carbon fiber-reinforced composite material of the invention exhibits high gas barrier properties, and particularly hydrogen gas barrier properties.

  • Patent number: 7972685
    Abstract: A composition of a fiber reinforced multi-layered laminate that when compression-molded forms a composite having a Class-A surface that is resin rich. The fiber reinforced multi-layered laminate has an outer layer of a cyclic polyester oligomer containing a latent polymerization catalyst; a glass mat; a core layer of a cyclic polyester oligomer containing a latent polymerization catalyst; a second glass mat, and another outer layer of a cyclic polyester oligomer containing a latent polymerization catalyst. When compression molded, the combination of heat and pressure force the core layer through the permeable glass mats and toward the surface. The latent polymerization catalyst initiates polymerization of the cyclic polyester oligomer forming a Class-A surface that is resin rich. The core layer of a cyclic polyester oligomer thoroughly permeates the reinforcing fiber forming a composite having a middle, with a nearly uniform mixture of reinforced glass fiber and thermoplastic in situ polymerized resin.
