Abstract
A new porous carbon material, named RB ceramics, has been produced utilizing a natural structure of rice bran. Rice bran is one of the industrial wastes and is 0.9 million tons per year in Japan . In this study, two types of strengthening method are tried for RB ceramics . One is a carbon material that is made of fine RB ceramics particles and phenol resin (CRB). The other one is a carbon material that is made of fine RB ceramics particles, phenol resin and carbon fibers. The both materials are significantly strengthened.
