  • Composite foam made from polymer microspheres reinforced with long fibers
    Patent number: 6864297
    Abstract: Composite foam based on expandable microspheres reinforced with fibers is described. Also disclosed are methods of making microsphere foam reinforced with fibers and methods of use thereof. The disclosure provides foam that performs equally and better than the performance of most thermoplastic foams commercially available.
    Type: Grant

    Date of Patent: March 8, 2005
    Assignee: University of Southern California
    Inventors: Steven R. Nutt, Lev Vaikhanski
  • Reinforced phenolic foam
    Patent number: 6841584
    Abstract: Disclosed are compositions of short fiber reinforced phenolic foams, methods of making and using the same. The disclosed fiber-reinforced phenolic foams have a seven-fold increase in peel resistance over the unreinforced counterpart foam. The phenolic foam has enhanced fracture toughness without sacrificing the critical fire retardant properties.
