  • Patent number: 5447977
    Abstract: A method of producing easily densified high bulk fibers that have adhered particulates. The fibers have hydrogen bonding or coordinate covalent bonding functionalities, and a binder is applied to the fibers to bind the particles to the fibers. The binder has a functional group that forms a hydrogen bond or a coordinate covalent bond with the particles, and a functional group that forms a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers are adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder is in turn adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

  • Patent number: 4863780
    Abstract: A coating of a viscous lubricant applied prior to stretch-breaking permits forming slivers of stretch-broken carbon fibers. When an anti-static ingredient is added to the viscous lubricant cohesive slivers of stretch-broken glass fibers can be formed. Composites of matrix resin reinforced with these slivers exhibit high strength, tensile stiffness, and good formability.

  • Patent number: 4839402
    Abstract: A metal-coated substrate, e.g., of glass, ceramic, or a hydroxy-functionalized material, wherein the improvement comprises a polysilicate, titania, or alumina interlayer between the substrate and the metal coating. The interlayer may have a porous microstructure, e.g., a polysilicate interlayer with an average pore size on the order of 50-150 Angstroms.Such articles, e.g., in the form of metal-coated fibers, may suitably be employed as reinforcing media in material composites having utility in structural applications, such as EMI shielding elements.Also disclosed is a corresponding method for forming a metal coating on a substrate by the provision of an interlayer of the above type. The interlayer may suitably be formed by applying to the substrate a sol gel dispersion of the polysilicate, titania, or alumina material, followed by drying of the applied dispersion.

  • Patent number: 4761440
    Abstract: In or for a polymeric article incorporating a synthetic polymer and a filler material, which filler material includes glass beads bearing coatings of at least one coating agent in a total coating amount not exceeding 1% and preferably between 0.02% and 0.2%, by weight based on the weight of uncoated beads, which coatings limit adhesion between the glass beads and the synthetic polymer and confer an increased impact resistance on the article as compared with an article which includes uncoated glass beads as filler material but is otherwise identical. Preferred coating materials include silanes, fluorocarbon compounds and synthetic polymers having shockabsorbing properties, especially synthetic polymers having a glass transition temperature (Tg), determined by differential scanning calorimetry, which is lower than 15.degree. C.

  • Patent number: 4727096
    Abstract: The invention relates to a composition of polymerizable resins reinforced with cut yarns of different lengths, such as glass yarns, and a process for its production. This composition comprises at least a representative of each of the following constituents: an unsaturated polyester, a thermoplastic polymer, a monomer liquid substance having at least a polymerizable reactive CH.sub.2 .dbd.C< group per molecule, an inert filler and optionally a thickening agent, a catalyst, an inhibitor and a releasing agent, the cut yarns being in the dispersed state in filament form for the longest ones, with the shortest yarns remaining in state of yarn formed from a multiplicity of filaments glued together. The process steps include making the mixture of the organic constituents and successively incorporating therein first the yarns previously coated with an insoluble lubricant, then the yarns coated with a lubricant which is soluble in the mixture.
