Abstract
There is provided a porous, carbon-containing preform, including a body (CL) of unidirectional carbon fiber fabrics (C), and a friction layer (FL) of randomly-arranged-carbon-fiber fabrics (F), combined with the body (CL) by a needle-punching operation. According to the present invention, it is by the needle-punching operation that the friction layer (FL) of the randomly-arranged-carbon fiber fabric (F) is formed on the body (CL) of the unidirectional carbon fiber fabric (C) and the friction layer (FL) of the randomly-arranged-carbon-fiber (F) is cross-linked to the body (CL) of the unidirectional carbon fiber fabric (C) in producing the porous, carbon-containing preform.
