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.

Abstract: A large-sized columnar body which is formed out of a fiber-reinforced plastic comprising continuous fibers and a resin, and which has three layers (A, B, C) laid in the mentioned order, characterized in that the reinforcing fiber in the B layer is carbon fiber arranged in the lengthwise direction of the columnar body, the fiber in the A layer and C layer being carbon fiber or/and glass fiber arranged at +/-50 to +/-70 degrees with respect to the lengthwise direction of the columnar body. This large-sized columnar body of FRP has a high compressive strength, so that the weight thereof can reduced to below that of a conventional large-sized columnar body. Accordingly, this columnar body is suitable as a primary structural material used as a building material, and for structures, aircrafts and ships.
