PURPOSE:To produce a carbon fiber reinforced carbon material having high density at low cost. CONSTITUTION:At first, a thermosetting resin is impregnated into a carbon fiber 1, which is formed into the shape in which the carbon fiber 1 is surrounded by the surface part of the thermosetting resin. Next, this formed body is calcined to convert the thermosetting resin into amorphous carbon. At this time, the temp. of the preliminary baking is regulated, and the calcination is finished in the state where hydrogen remains. Next, this calcined product is subjected to hot isostatic pressing treatment. In this way, graphite is stuck to the carbon fiber 1, by which a carbon fiber reinforced carbon material 3 can be obtd. |
