PURPOSE:To improve ecomicity keeping strength at some extent by deciding component in due consideration of carbonization ratio of a raw material for a matrix and fiber content of a final product in the production method in which mixture of a carbon fiber and a raw material for a matrix is formed, hardened and carbonized. CONSTITUTION:Component of a raw material for a matrix and a carbon fiber are respectively decided from carbonization ratio of a raw material for a matrix and fiber content of a final product and mechanically mixed. After this mixture is formed in applying pressure, a product is hardened and then carbonized in applying pressure. When forming, hardening and carbonizing are carried out, a raw material for a matrix is vaporized, and a part of blow holes is filled with an external raw material for a matrix, and densification is attained. Thus repeated process is not necessary and a favorable carbon fiber reinforced carbon composite material can be obtained in a short time. |
