  • METHOD FOR MANUFACTURING COMPOSITE FIBER PREFORM FOR DISC BRAKES
    Publication number: 20230057890
    Abstract: An example method includes combining an interlayer and a carbon fiber fabric, wherein the interlayer comprises a highly oriented milled carbon fiber ply comprising a plurality of out-of-plane carbon fibers. The method further includes winding the interlayer and the carbon 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.
    Type: Application
