  • Susceptor integration into reinforced thermoplastic composites
    Patent number: 5935475
    Abstract: Problems associated with accurately positioning a susceptor at the bond line between two or more prefabricated, fiber reinforced, resin composite detail parts to facilitate thermoplastic welding (i.e., fusion bonding) between the detail parts. The integrated susceptor detail part is compatible with Z-pinning along the bond line for the pulloff strength enhancement associated with Z-pin reinforcement. We make the parts by (1) preparing the faying overface of the prefabricated part or prepreg preform for the overlayment of the bond line materials, (2) placing a thermoplastic film on the part or preform, (3) placing the susceptor on the film, and (4) securing the film and susceptor to the part by applying suitable heat and pressure to produce a prefabricated, consolidated detail part having an integrated susceptor in a resin rich region intended as the bond line to other parts in the final assembly.

  • Annealed thermoplastic weld
    Patent number: 5925277
    Abstract: The present invention is a method for improving the strength and quality of thermoplastic welds by annealing the weld following its formation at a temperature of at least about 500.degree. F. (i.e., about 125.degree. F. below the melt) for about 20 minutes to control cooling of the weld.

  • Post-weld annealing of thermoplastic welds
    Patent number: 5869814
