  • Method and device for continuous formation of braid reinforced thermoplastic structural and flexible members
    Patent number: 5468327
    Abstract: A braided fiber reinforced thermoplastic member is formed by a device, which comprises a braiding device for weaving thermoplastic coated fibers with second fibers onto a weaving mandrel for form a braided preform, and a heating die for melting the thermoplastic of the coated fibers of the braided preform to form a continuous matrix of thermoplastic between the coated fibers and the second fibers. A method for forming a fiber reinforced thermoplastic member comprises coating carbon fibers with a thermoplastic melt, cooling the thermoplastic coated carbon fibers, braiding the coated carbon fibers onto a weaving mandrel with Kevlar.RTM. bias fibers to form a braided preform, and drawing the braided preform through a heating die.
