  • Optically clear structural laminate
    Publication number: 20050042457
    Abstract: An optically clear structural laminate includes a thermosetting resin, a silane coupling agent and a filler. The laminate has a high weight to strength ratio and is capable of optical transmission over a wide range of temperatures. The laminate has increased tensile strength and is capable of being easily formed into complex shaped components. The structural properties of the laminate make it useful as aircraft canopies and windows.

  • Thermoplastic syntactic foams and their preparation
    Patent number: 5691390
    Abstract: A low-density, porous material is prepared by mixing together microballoons and an oligomeric precursor to a polyesterimide polymer. The oligomeric precursor has an initial viscosity sufficiently low that it can flow and wet the microballoons when first heated to a polymerization processing temperature, and thereafter polymerize. Fibers may be controllably incorporated into the material during processing to impart specific properties, and air may be controllably incorporated into the material during processing to further decrease its density.
    Type: Grant
    Filed: March 20, 1996
    Date of Patent: November 25, 1997
    Assignee: McDonnell Douglas Corporation
    Inventors: Edward S. Harrison, Edward J. Ruskowski, James Melquist
  • Thermoplastic syntactic foams and their preparation
    Patent number: 5532295
    Abstract: A low-density, porous material is prepared by mixing together microballoons and an oligomeric precursor to a polyetherimide polymer. The oligomeric precursor has an initial viscosity sufficiently low that it can flow and wet the microballoons when first heated to a polymerization processing temperature, and thereafter polymerize. Fibers may be controllably incorporated into the material during processing to impart specific properties, and air may be controllably incorporated into the material during processing to further decrease its density.
