    摘要： An example method includes forming an interlayer on a carbon fiber fabric to form a composite fiber fabric. The interlayer comprises a binder. The method further includes winding the composite fiber fabric around a core to form a composite fiber preform comprising a plurality of layers defining an annulus extending along a central axis. The method further includes densifying the composite fiber preform, wherein the binder comprises at least one of a resin, a thermoset resin, or a phenolic resin, wherein depositing the interlayer comprises:
    depositing the binder in a dry powder form onto the carbon fiber fabric;
    compressing the binder to the carbon fiber fabric prior to winding the composite fiber fabric; and
    curing, after winding, the binder, wherein the interlayer comprises a plurality of nanoparticles in the binder, the method further comprising blending the plurality of nanoparticles with the binder prior to depositing the interlayer, wherein the plurality of nanoparticles comprise at least one of a carbon nanotube, a carbon nanofiber, or a graphene nanoplatelet.

    摘要： A carbon-carbon composite material is made by providing an open-celled carbon foam preform, and densifying the preform with carbonaceous material. The open-celled carbon foam prefrom may be oxygen stabilized prior to carbonization, and the foam preform densified by CVD, HIP, PIC, VPI, pitch and resin injection, or any combination thereof. The carbon-carbon composite material can be heat treated to provide thermal management materials, structural materials, or a friction material for use in a brake or clutch mechanism.

    摘要： Carbon fiber brake preforms (20), specifically, annular discs built up of fabric arc segments (21) composed of continuous fibers (25) and staple fibers (26). Most of the continuous fibers (25) in the fabric segments (21) are arranged to be located within 60° of radially from the inner diameter to the outer diameter of the annular disc (20). The fabric arc segments have substantially all of their continuous fibers oriented in the radial direction and parallel to the segment arc bisector, or the segments are arranged in alternating layers in which, respectively, half the continuous fibers are oriented at a +45 degree angle with respect to the segment arc bisector and half the continuous fibers are oriented at a -45 degree angle with respect thereto. Methods for making preform composites comprise providing needle-punched nonwoven fabric of unidirectional continuous fibers and staple fibers, making a plurality of fabric segments, arranging the segments in a multilayered intermediate, heating the multilayered intermediate to convert the fibers to carbon, and densifying the carbonized product. In brake discs made as described, fiber pull-out is minimized , reducing mechanical wear. The disclosed preform fiber architecture reduces wear rates while maintaining brake disc strength.
