    摘要: A pitch densification apparatus may be used to form a carbon-carbon composite material. In some examples, the apparatus is configured to pitch densify a material using one or more of a plurality of different pitch densification techniques. For example, the apparatus may densify a material with a selectable one of the resin transfer molding cycle, the vacuum-assisted resin transfer molding cycle, and/or the vacuum pressure infiltration cycle. The apparatus may respond to initial or changing properties of a material to be densified. In some additional examples, the apparatus includes a mold configured to receive a preform and a portion of solid pitch separate from the preform. The apparatus may include a heating source thermally coupled to the mold that is configured to heat the solid pitch above a melting temperature of the solid pitch. The apparatus may melt the pitch without external pitch melting equipment.

    摘要: A pitch densification apparatus may be used to form a carbon-carbon composite material. The apparatus may be used to compress a carbon fiber material, and, thereafter, pitch densify the carbon fiber material. The compression and pitch densification of the carbon fiber material may be carried out within the same mold cavity of the pitch densification apparatus. In one example, an apparatus may comprise a mold defining a mold cavity that is configured to receive a material to be densified. The mold cavity is configured to be adjusted from a first volume to a second volume less than the first volume to compress the material in the mold cavity. The example apparatus may further comprise a gas source configured to apply a gas pressure in the mold cavity to force pitch into the material in the mold cavity to densify the material, and a vacuum source configured to create a vacuum pressure in the mold cavity at least prior to the application of the gas pressure.

    摘要: A method of manufacturing a carbon-carbon brake disc uses a restraint fixture (12) that includes a preform retention region configured to limit contracting forces applied against a preform (10) in the preform retention region when the restraint fixture (12) thermally contracts. In one embodiment, the restraint fixture (12) comprises a band (12) having a first surface defining the preform retention region and a first expansion portion (26, 28, 29) adapted to deform upon application of a force to the band (12).

    摘要: An improved brake shoe assembly is provided wherein friction material is cast directly onto a brake liner plate. The brake liner includes a plurality of perforations which form protruding tabs. Interengagement between the cast friction material and the perforated areas and tabs provides excellent interlocking strength between these components. The number, size, orientation and configuration of these tabs may be selected with regard to the specific operating characteristics to which the brake shoe assembly is to be employed.

    摘要: A heated brake shoe press has a longitudinal open end cavity defined by a base and cover. One end of the cavity may be closed by a movable platen. A movable plunger projects into the other end of the cavity and is slideably engaged with the cavity throughout its length. Inserts and liners are slideably engaged in the cavity in a given order and define a plurality of molding cavities that are fillable with moldable material. The heat, and the pressure exerted by the plunger configures the material in the molding cavities to a shape defined by the inserts and liners. After forming, the platen may be moved to an open position and the inserts and configured material may be pushed out of the cavity by the plunger. To accommodate such action and to reduce galling and scoring of the cavity walls, Teflon buttons are attached to the insert faces which engage the cavity wall.
