  • Building complex for disposing of toxic and otherwise hazardous waste materials
    Patent number: 6044596
    Abstract: A building complex for disposing of toxic or otherwise hazardous waste materials. The complex comprises heptagonal shaped center core structure and five rhomboid shaped wing structures dedicated to waste disposal. The walls, floors and ceilings of the wings include a layer or layers of a composite material comprising a thermosetting or thermoplastic resin, high modulus carbon fibers or the like and borosilicate glass particulate.
    Type: Grant
    Filed: February 16, 1999
    Date of Patent: April 4, 2000
    Assignee: Tox-Wastech, Inc.
    Inventor: Richard A. Driggett
  • High Strength composite materials
    Patent number: 5902755
    Abstract: A ternary composite with thermal stability of up to at least 200.degree. C. Is formed using a thermally stable matrix resin, high tensile fibers, and borosilicate or sodium tetra borate glass particulates. The composite has stability to acids, toxic wastes and may be formed into sheets, shapes, tubes, containers, flooring materials and the like for use in aerospace, defense, automotive, industrial, nuclear containment or simply building material applications.

  • High strength acid stable composite materials
    Patent number: 5624744
    Abstract: A ternary composite with thermal stability of up to at least 200.degree. C. is formed using a thermally stable matrix resin, carbon fibers, and borosilicate glass particulates.The composite has stability to acids, toxic wastes and may be formed into sheets, shapes, tubes, containers, flooring materials and the like. The composite may have unevenly distributed borosilicates, enhancing one surface's ability to withstand strong acid conditions.
