  • Composite rim and reinforced prepreg thereof
    Patent number: 11541687
    Abstract: A reinforced prepreg which is applied to a wear-resistant layer structure of a braking track is provided. The reinforced prepreg includes a fiber fabric and a mixture mixed with the fiber fabric. The mixture includes a resin and a plurality of needle-shaped crystals having microscale or nanoscale sizes mixed with the resin.
    Type: Grant

  • Resin-based composite structure and method for forming resin-based composite structure
    Patent number: 11364690
    Abstract: A method for forming a resin-based composite structure is provided. The method includes: providing a prepreg layup, wherein the prepreg layup includes an epoxy resin-carbon fiber composite material; covering a thermal-fusion material on a surface of the prepreg layup; and performing a molding and curing process to fuse the thermal-fusion material with the prepreg layup. Wherein the molding and curing process includes: heating at a first temperature to melt, soften and fully fuse the thermal-fusion material with the prepreg layup; and heating at a second temperature to solidify the thermal-fusion material for forming the resin-based composite structure. Wherein the first temperature is lower than the second temperature.
