  • Method for preparing interpenetrated polymer films
    Patent number: 5501831
    Abstract: This invention relates in general to a method for the formation of films having a controlled molecular orientation prepared from rod-like extended chain aromatic-heterocyclic ordered polymers, and containing a binder in the micro-infrastructure. Such films have high tensile strength, modulus, and environmental resistance characteristics.
    Type: Grant
    Filed: August 19, 1994
    Date of Patent: March 26, 1996
    Assignee: Foster-Miller, Inc.
    Inventors: Robert Kovar, Roland R. Wallis, Jr.
  • Interpenetrated polymer fibers
    Patent number: 5168011
    Abstract: This invention relates in general to the formation of fibers having a controlled molecular orientation prepared from rod-like extended chain aromatic-heterocyclic ordered polymers, and containing a binder in the micro-infrastructure. Such fibers have high tensile strength, modulus, and environmental resistance characteristics.

  • Composite structure reinforcement
    Patent number: 4808461
    Abstract: Translaminar reinforcement structure for localized Z-direction reinforcement of composite structure includes a body of thermally decomposable material that has substantially opposed surface, a plurality of reinforcing elements in the body that extend generally perpendicularly to one body surface, and pressure intensifying structure on the other opposed body surfaces for applying driving force to the reinforcing elements for insertion into the composite structure as the body is subjected to elevated temperature and decomposes.
