    Abstract: Mask (10, 10′, 21, 22, 30) for use in coating a carbon-carbon composite brake disc (25) with anti-oxidant. The mask is composed of carbon-carbon composite material or nonreactive ceramic material. The mask is configured with edge ridges (11, 13, 34, 36) that are aligned with the outer and inner annular diameters of the carbon-carbon composite brake disc, a gas flow channel (12, 32) between the ridges, and a gas access port (18, 40) that allows gas to enter the gas flow channel. The mask may also include a gas exit port (16) having a valve (17) operatively connected thereto, so that gas flow may be restricted when pressure within the mask and carbon-carbon composite brake disc falls below a specified minimum value. Also, a method of avoiding application of liquid antioxidant material to a friction surface of a carbon-carbon composite brake disc, by: covering the friction surface with a mask configured to deliver compressed gas to the friction surface, and directing compressed gas across the friction surface and through pores in the carbon-carbon composite brake disc and/or in the mask while the masked brake disc is in the presence of the antioxidant material in a liquid state.

    Abstract: Method of manufacturing dense carbon-carbon composite material by: infiltrating a fibrous preform with pitch to form pitch-infiltrated preform; carbonizing the pitch-infiltrated preform; injecting resin or pitch into the preform in a mold; oxygen stabilizing the filled preform and carbonizing and heat-treating the oxygen-stabilized impregnated preform; and subjecting the preform to a single final cycle of chemical vapor deposition. This process reduces densification time as compared to comparable conventional carbon-carbon composite manufacturing procedures.

The adhesive distributing portion includes a plurality of passageways therethrough in communication with the first passageway of the base portion. The plurality of passageways of the adhesive distributing portion extend to the exterior of the adhesive distributing portion. An adhesive pump forces adhesive to and through the first passageway of the base portion and into and through the plurality of passageways of the adhesive distributing portion to the exterior of the adhesive distributing portion. Adhesive emanates from the exterior of the adhesive distributing portion under the force of the adhesive pump and coats the threads of an internally threaded device. Another example coats the threads of an externally threaded device. Processes for coating internal and external threads are disclosed.

    Abstract: 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.
