PURPOSE:To improve yield of carbon fibers to be used while making a frictional member hold sufficient strength by using a carbon fiber fabric by laminating parts as a prepreg, formed by dividing a doughnut shape, and entangling the carbon fiber sticking out from the cut part into the prepregs positioned on the upper and lower parts. CONSTITUTION:A prepreg wherein self-impregnant carbon powder is taken as a matrix is prepared by the electrodeposition process by using a PAN carbon fiber. Many parts having the size and the shape that a doughnut shape is divided into eight parts are formed by cutting the obtained rectangular prepreg 1. The prepregs obtained by being cut are arranged into a doughnut shape, and the doughnut shapes are laminated. Next, the laminated body is pressurized and sintered after being pressurized and formed, so as to obtain a doughnut-shaped carbon fiber reinforced carbon compound material. A frictional member having high share strength can be manufactured at a low cost without deteriorating frictional properties. |
