  • Patent number: 6696144
    Abstract: The present invention is a low density hybrid airfoil comprising a temperature resistant exterior layer and a tough, high impact resistant interior layer. Specifically, the airfoil comprises a monolithic ceramic exterior layer and a fiber reinforced ceramic matrix composite interior layer. Both the monolithic ceramic and fiber reinforced ceramic matrix composite are low density materials. Additionally, the monolithic ceramic is a high temperature resistant material, and the fiber reinforced ceramic matrix composite is a relatively high impact resistant structure. Encapsulating the airfoil with a temperature resistant exterior layer protects the airfoil in a high temperature environment, and supporting the airfoil with a high impact resistant, fiber reinforced ceramic matrix composite improves the overall impact resistance of the airfoil thereby resulting in a tough, high temperature resistant, low density airfoil.

  • Patent number: 6685871
    Abstract: Toughened biaxially oriented polyamide films prepared by dry blending i) a polyamide homopolymer, copolymer, or blends thereof; and ii) a functionalized polyolefin terpolymer comprising maleic anhydride, ethyl acrylate, and an olefin, to thereby form a dry mixture. The dry mixture is melted to form a polymer blend, which is then formed into a polymer film. The edges of the film are pinned to a casting roll, and the film is plasticized in at least one water bath. The polymer film is subsequently biaxially oriented. The result is a toughened biaxially oriented film which is resistant to pinholes, cracks, and other structural defects. Such films are particularly suited for making packaging materials for various food products.

  • Patent number: 6607818
    Abstract: A visually decorative material having bulk decorative effects which may be used as a surface covering or for creating decorative objects, and the method of manufacturing same. The material is formed of a pigmented castable liquid vehicle such as a resinous polymer or glass having dispersed therein a quantity of discrete particles which have a higher specific gravity than the liquid vehicle. The material is formed by pouring the vehicle-particle composite onto a suitable backing. As the liquid flows onto the backing, the particles sink and disturb the uniformity of the pigment distribution. This causes the desired bulk decorative effects in the form of “comet-tails” and other dimensionally extended streaks and curves. The backing may be removed after the castable liquid solidifies or may be left in place to create a laminate. As a floor-covering, the material may be poured in place onto a suitable sub-flooring. A protective surface coating may also be applied to the solidified casting.

  • Patent number: 6599622
    Abstract: A thermoplastic film having a substantially continuous, adherent coating on at least one surface, wherein the coating includes a polymeric binder and nano-scale particles. When the coating is formed on the surface of the film, the nano-scale particles form a barrier that substantially reduces the diffusion of moisture and oxygen. In preferred embodiments, the coating includes a polymeric binder and silicate particles formed on a base substrate layer that includes a polyolefin selected from the group consisting of homopolymers, copolymers, and terpolymers of propylene, ethylene, butylene, and blends thereof.
