摘要： Method of making a carbon-carbon composite article such as an aircraft brake disc. The method includes: selecting carbon fiber precursors, having limited shrinkage in the axial direction when carbonized, in the form of individualized chopped or cut fibers; placing the selected chopped or cut carbon fiber precursors into a preform mold configured in the form of a brake disc to form a fibrous matrix; and then needling the molded fibrous matrix to provide it with three-dimensional structural integrity and to reduce layering. The carbon fiber precursor matrix may subsequently be infused with liquid carbon matrix precursor, the impregnated matrix may be carbonized; e.g., at 600-1800° C. for 1-10 hours to provide a preform having a density of at least about 1.1 g/cc, and the carbonized preform may be further densified to a density of at least about 1.6 g/cc by known liquid resin infiltration techniques and/or by conventional CVI/CVD processing.

The apparatus includes e.g. an extruder (4) for melting and conveying a resin or pitch and a mold (10) arranged so that resin or pitch is conveyed to a mold insert cavity (19) within the mold. The mold insert contains an internal protrusion such as a locating ring (25) for positioning a porous body (1, 18) within the mold insert cavity in a position that brings about unidirectional flow of the molten resin or pitch through the porous body. Also, rapid resin or pitch infiltration molding process that includes injecting a high melting point, high viscosity, molten resin or pitch into the mold to effect a unidirectional impregnation of a heated preform via a pressure gradient in the mold.
