To obtain a method of manufacturing a C/SiC precursor in which carbon fibers are two-dimensionally and randomly arranged in the main surface direction and are arranged in layer in the vertical direction to the main surface without causing the swelling, the laminar crack or the deformation.
The method of manufacturing a C/SiC precursor is performed by a process for housing a carbon fiber formed body in a shape holding vessel having a dimension capable of housing the carbon fiber formed body, a process for impregnating the carbon fiber formed body housed in the shape holding vessel with an impregnating agent capable of being carbonized, a process for taking out the impregnated carbon fiber formed body obtained by impregnating the carbon fiber formed body with the impregnating agent from the shape holding vessel and firing and carbonizing the impregnated carbon fiber formed body while pressurizing and a process for firing and graphiting the the carbonized fired body obtained by firing and carbonizing the impregnated carbon fiber formed body while pressurizing.
