Abstract
The carbon fibers of the present invention have a polymer having polar groups and groups capable of reacting with a matrix resin deposited on the fiber surfaces. The carbon fibers can be produced by depositing a monomer having both polar groups and groups capable of reacting with the matrix resin or a mixture of a monomer having polar groups and a monomer having groups capable of reacting with the matrix resin onto the fiber surface and heating to polymerize the monomer(s) forming a polymer having polar groups and groups capable of reacting with a matrix resin. The resultant fibers have excellent adhesion properties to the matrix resin and are unlikely to cause fluffing and fiber breakage.
