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: The carbon fibers of the present invention have the are configuration as stated below to achieve the object: carbon fibers, characterized in that a polymer having polar groups and groups capable of reacting with a matrix resin are deposited on the fiber surfaces. Furthermore, the carbon fibers of the present invention can be produced by heating the carbon fibers, on the surfaces of which either (1)a monomer having both polar groups and groups capable of reacting with the matrix resin, or (2)the mixture of a monomer having polar groups and a monomer having groups capable of reacting with the matrix resin, is deposited, to polymerize the monomer. The present invention can provide carbon fibers unlikely to cause fluffing and fiber breaking even if rubbed by guide bars and rollers in sophisticated processing, and since they are excellent in adhesion properties to the matrix resin, a carbon fiber reinforced composite material excellent in bending properties and compressive properties can be obtained.
