  • Publication number: 20100255270
    Abstract: The present invention provides a fabric and a fabric structure made of yarns with reduced water absorption. The fabric comprises yarns and interstices between the yarns, the interstices between the yarns having an average width of greater than 100 ?m. At least one of the yarns is comprised of multiple fibers. Said at least one yarn has voids between the fibers wherein the voids are filled up with a polymer material. The interstices remain open and the size of the interstices is the same as before the treatment. The filling of the voids between the fibers with the polymer material prevents the absorption of water into said voids and therefore leads to reduced water absorption of the fabric. The polymer material is substantially only located within the voids of the yarn and has embedded the fibers within the outer surface of said yarn.

    Abstract: A protective covering constructed from an electrostatically charged sheet having a top and bottom surface and an absorbent layer. The absorbent layer has top and bottom surfaces, the bottom surface of the absorbent layer being bonded to the top surface of the electrostatically charged sheet. The absorbent layer is divided into a plurality of cells for containing liquid spilled on the absorbent layer. The absorbent layer can be constructed from paper, open cell foam, fibrous mat, or any other absorbent material. In the preferred embodiment of the present invention, the cells are constructed by providing hydrophobic barriers in the absorbent layer. The barriers can be constructed from paraffin, plastic, or any other material that can penetrate the absorbent layer. In one embodiment of the present invention, a hydrophobic layer is bonded to the top surface of the absorbent layer.

  • Patent number: 7754321
    Abstract: A manufacturing method of a clad board includes: sticking a releasing film to a pre-preg sheet; forming a non-through-hole or through-hole in the pre-preg sheet including the releasing film; filling the hole with conductive paste; peeling off the film; and heating and pressing a metal foil onto the pre-preg sheet. The clad board has a smooth face formed on one face or both the faces of the pre-preg sheet, so that the conductive paste is restrained from spreading in an interface between the pre-preg sheet and the releasing film. This structure can avoid short-circuit between circuits and prevent insulating reliability from lowering. As a result, an yield rate is improved, and a reliable circuit board is obtainable.

    Abstract: A resin composition that is storable at ambient temperatures. The resin composition forms a cured resin when exposed to a curing agent and heated to a curing temperature that is relatively close to ambient temperature. The resin composition includes a resin component that is composed of a liquid part that is made up of one or more liquid thermosetting resins and a solid part that includes particles of one or more solid thermosetting resins. The liquid part further includes a gelation agent that is present in a sufficient amount to maintain the particles in suspension within the liquid part at ambient temperatures. The viscosity of the resin component changes from a high viscosity state to a low viscosity state when the temperature is increased from ambient temperature to the curing temperature. The high viscosity state is substantially more viscous than the low viscosity state.

  • Patent number: 6902798
    Abstract: A flexible seal for use in a solid oxide fuel cell stack is formed from a fiber matrix impregnated with a plurality of solid particles. The fibers and particles are preferably ceramic and may be formed from alumina or zirconia. The seal may be formed by dipping the fiber matrix into a slurry of the particles in an alcohol, drying the seal and precompressing prior to installation in the fuel cell stack.

  • Patent number: 6893712
    Abstract: The transport member of the present invention is a laminate of skin and core layers made of CFRP. The skin layer comprises a prepreg made of a pitch type carbon fiber, oriented by ?20° to +20° with respect to a longitudinal direction (X-axis direction) of the transport member, having a tensile elasticity of 500 to 1000 GPa; and a prepreg of PAN type carbon fiber, oriented by +75° to +90° and/or ?75° to ?90° with respect to the longitudinal direction, having a tensile elasticity of 200 to 400 GPa. As a consequence, a transport member which is light in weight, easy to handle, while being excellent in its bending rigidity, vibration damping characteristic, and heat resistance can be obtained.

  • Patent number: 6890481
    Abstract: The present invention provides a porous paper product impregnated with at least one chemical species. The porous paper product can be in the form of sheets, or compressed pellets. The porous paper can be prepared from a variety of sources, including wood pulp, kenaf, flax, or hemp. The chemical species impregnating the paper react and/or diffuse out of the paper to accomplish a variety of desired results. For example, diffusion of a volatile biocidal chemical out of pores in the paper create a no-growth zone on and immediately surrounding the impregnated paper. In this manner the impregnated paper can provide a sterile environment for activities such as food packaging/storage, the treatment of illness/injury, or waste disposal.

  • Patent number: 6890637
    Abstract: The invention is directed to a plastic fiber article of manufacture having composite-like high strength characteristics. The article of manufacture can be in the form of a panel or board. The panel or board is constructed from low cost fiber materials, industrial grade or high thermal plastic, and other additives to protect the board or panel from ultraviolet light, fugi growth, excessive heat, fire, insect infestation, and/or weathering. The plastic fiber panel or board may be textured and colored to resemble natural wood such as cedar, walnut, or oak. The plastic fiber panel or board is stronger more durable and may be cheaper than natural wood alternative panels or boards.

  • Patent number: 6863971
    Abstract: The present invention concerns treated fibrous porous material having a defined nanostructure comprising reactive sites thereon, wherein said fibrous porous material is treated with a low viscosity organic solution comprising organic solvent, isocyanate component unsaturated resin and optionally additional additives. The treated fibrous porous material is further mixed with a resin to form a composite. The composite may be formed by various methods of mixing and molding. The invention is further directed to various composites made therefrom. The fibrous porous material is selected from the group comprising cellulose, lignin, synthetic ceramics, porous metal nanopowders, kaolin, bio fibers and porous powders of biological origin or their mixtures. The resin may be any polymer virgin or scrap obtained from industrial or domestic waste, and is selected from thermoplastic or thermosetting polymers.

  • Patent number: H2133
    Abstract: A composite structure having a substrate is protectively covered during fabrication by a barrier layer, such as an intumescent mat or felt, into which a fire resisting agent such as phenolic resin or water, or oil based intumescent coating is infused in-situ before attachment to the substrate and completion of composite structure fabrication. The barrier layer is infused in-situ with the phenolic resin before attachment by adhesive bonding to the substrate or infusion is performed during formation of the underlying substrate layer so as to achieve attachment without adhesive.
