摘要
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.
