Abstract
A method and apparatus for making carbon/carbon composite discs for an aircraft brake employs a continuous feeding of fiber strands into a mold. Water is then combined with the fibers and the fibers are compressed to form a moisturized mat or preform. The fibers are then needled such that the fibers within the mat or preform extend in radial, circumferential, and axial directions. The mat or preform is then subjected to densification. The resulting disc is of total carbon construction. The water introduced into the mat during the processing serves as both a sacrificial binder and a lubricant during the fabrication.
