Abstract: The object of the present invention is to provide carbon fibers with high tensile strength as a resin impregnated strand even if the single filaments constituting the carbon fibers are thick. The carbon fibers of the present invention consisting of a plurality of single filaments are characterized by satisfying the following relation: where sigma is the tensile strength of said carbon fibers as a resin impregnated strand (in GPa) and d is the average diameter of said single filaments (in mu m). The carbon fibers can be preferably used as a material for forming energy-related apparatuses such as CNG tanks, fly wheels, wind mills and turbine blades, a material for reinforcing structural members of roads, bridge piers, etc., and also a material for forming or reinforcing architectural members such as timber and curtain walls.

Abstract: A prepreg comprising noncircular cross-section carbon fibers and a matrix resin having a flexural elastic modulus of 2.7 GPa or more and a water absorption of 3.4 % or less under hot-wet conditions after curing; and another prepreg comprising carbon fibers and a matrix resin having an open-hole compression strength under hot-wet conditions and a compression strength after impact under room-temperature conditions of a quasi-isotropic material after curing of each 275 MPa or more. Carbon fiber-reinforced composite materials produced by curing these prepregs are excellent in open-hole compression strength under hot-wet conditions and in compression strength after impact, and can be suitably used especially as an aircraft primary structure material.

Abstract: Carbon fiber of which the tensile strength of resin-impregnated strand is high even when the thickness of each monofilament constituting the carbon fiber is large. This carbon fiber is characterized in that it comprises a plurality of monofilaments, and satisfies the relation sigma >/= 11.1 - 0.75 d, where d (unit: mu m) represents an average diameter of the monofilaments; and sigma (unit: GPa) the tensile strength of the resin-impregnated strand of the carbon fiber. This carbon fiber is preferably used as a material for forming energy-related equipment and parts, such as CNG tanks, flywheels, windmills and turbine blades, as a reinforcing material for structural equipment and parts, such as roads and bridges, and as a building and reinforcing material for a constructional material, such as lumbers and curtain walls.
