The strength of circumferentially wound carbon-fiber reinforced carbon bodies is vastly improved if the reinforcing fibers are wound loosely, to a width greater than the axial thickness of the desired carbon body, and then axially compressed to cause radial overlapping of the carbon fibers. This technique is particularly useful for carbon bodies having an irregular perimeter, such as brake discs containing keyways or other indentations for bearing circumferential stress, since the reinforcing fibers adjacent to the stress-bearing perimeter can be made to conform substantially to the shape of the perimeter and the indentations therein. |
