Abstract
Disclosed herein are a carbon fiber-reinforced carbon composite material composed of carbon as a matrix and carbon fiber as a reinforcement, and also a process for producing the same. The composite material is produced by coating nonwoven fabrics of carbon fiber or a blend of carbon fiber and organic fiber with a filler-containing liquid, laminating the nonwoven fabrics one over another, and subjecting the laminated nonwoven fabrics to needle punching repeatedly with a plurality of needles, thereby yielding a prepreg of three-dimensional structure, and carbonizing and calcining the thus obtained prepreg.
