A method of manufacture for a carbon/carbon part including a method to remove contamination from an intermediate product of the carbon/carbon part and furnace utilizing a gaseous reducing agent hydrogen gas to reduce the contaminates, thereby causing the contaminates to transition to a gaseous state at relatively lower temperatures. A method to remove contamination from an intermediate product of the carbon/carbon part and furnace utilizing hydrogen gas to reduce the contaminates, thereby causing the contaminates to transition to a gaseous state at relatively lower temperatures.

A method of making a fibrous part is provided. The method may comprise forming a porous structure with an annular geometry. A first entrance channel and a second entrance channel may be formed with the entrance channels defined by a surface of the preform. The entrance channels may also extend in a radial direction from an inner diameter of the annular porous structure partially across the surface. An exit channel may be formed between the entrance channels and defined by the surface. The exit channel may extend in a radial direction from an outer diameter of the annular porous structure partially across the surface.

A brake assembly for use in a disc brake mechanism of a vehicle. The brake assembly includes an aluminum ceramic composite rotor connected to a central aluminum hub. The rotor includes projections extending radially inward toward the hub and engaging with through holes in the hub. The projections extend through the through holes to connect the rotor to the hub. The engagement between the projections and the through holes allows for radial movement of the projections relative to the through holes, which radial movement may be caused by thermal expansion of the rotor from heat generated during a breaking operation.

Systems and methods for infiltrating a fibrous preform in the in-plane direction and forming composite components are provided. A system for infiltrating a fibrous preform may include a slurry reservoir defining a cavity configured to receive a fibrous preform. The cavity may be configured such that an internal surface of the slurry reservoir is spaced apart from an outer diameter of the fibrous preform. A slurry inlet may be formed in the slurry reservoir. The slurry inlet and the cavity may be configured such that a slurry input into the cavity infiltrates the fibrous preform in an in-plane direction.

An article includes a structural core, one or more friction pads, and a plurality of elongated fasteners. The structural core includes two core surfaces and a plurality of pockets extending between the core surfaces. Each friction pad includes a pad surface and a friction surface opposite the pad surface. Each pad surface includes a planar pad surface configured to contact the core surface and a plurality of bosses extending from the first planar pad surface and including a bore. Each planar pad surface is at least about 50% of a surface area of the respective first and second pad surfaces. The plurality of bosses engages with the plurality of pockets to position the respective first and second friction pads relative to the structural core. The plurality of elongated fasteners passes through bores of corresponding bosses of friction pads to fasten the friction pads to the structural core.

Shaped material (1), in particular a disc for a disc brake includes layers (2, 4, 6) of carbon fibers stacked in a construction direction (X). Each layer (2, 4, 6) has segments (8, 10) placed side by side and joined together to form the layer, the segments of a layer (2, 4, 6) include radial segments (8) and transverse segments (10). In each layer (2, 4, 6) of carbon fibers, the number of transverse segments (10) is greater than the number of radial segments (8). A method manufactures a shaped material.

A seal plate disposable between a pair of preforms for chemical vapor infiltration is disclosed. The seal plate may include a plurality of first channels that extend completely through the seal plate and that are located between an inner annulus and outer annulus of the seal plate. The seal plate may further include a plurality of second channels that also extend completely through the seal plate and that are located also between an inner annulus and outer annulus. The first channels may differ from the second channels in at least one respect (e.g., the first channels may be of a different width than the second channels). The first channels may provide an inlet for the chemical vapor infiltration of the preform, while the second channels may provide an outlet for the chemical vapor infiltration of the preform.
