    Abstract: The present invention provides a flame-retardant or nonflammable decorative sheet which is a one-piece laminate of the following materials: one layer or two or more layers of a sheet material for a core layer, obtained by impregnating a base sheet material made of an inorganic fiber, with a composition comprising a phenolic resin and/or a melamine resin and aluminum hydroxide and/or magnesium hydroxide, the proportions of the former and the latter in the composition being 4-15% by weight and 96-85% by weight, respectively, and a sheet material for a decorative layer, placed on at least one side of the sheet material for the core layer. When the sheet material for the core layer consists of two or more layers, there can be interposed, between the layers of the sheet material for the core layer, a sheet material for a reinforcing layer obtained by impregnating a base sheet material made of an inorganic fiber, with a thermosetting resin.

  • Patent number: 6114005
    Abstract: A laminate capable of mounting semiconductor elements thereon; comprising an insulating layer which is constituted by a resin portion of sea-island structure and a woven reinforcement. The resin portion of sea-island structure is, for example, such that a resin as islands are dispersed in a resin as a matrix. Thus, the insulating layer exhibits a coefficient of thermal expansion of 3.0.about.10 (ppm/K) in a planar direction thereof and a glass transition temperature of 150.about.300 (.degree.C.). Owing to these physical properties, thermal stresses which the laminate undergoes in packaging the semiconductor elements thereon can be reduced, so that the connections of the laminate with the semiconductor elements can be made highly reliable.

  • Patent number: 6051317
    Abstract: The invention relates to sheet-like absorbents for water and aqueous solutions, containing at a defined distributionA) at least one water-swellable synthetic and/or natural superabsorbent polymer, andB) at least one water-soluble synthetic and/or natural polymeras a matrix of sheet-like design wherein the superabsorbent component A) is integrated or fixed. The sheet-like absorbents have an increased absorptive capacity for water and aqueous liquids, particularly under load. They are manufactured by forming a sheet-like matrix from the water-soluble synthetic and/or natural polymers B) and providing same with said water-swellable synthetic and/or natural superabsorber A), e.g., by applying a solution of matrix B) on a surface, sprinkling same with component A), and drying the sheet-like structure thus obtained.

  • Patent number: 5985772
    Abstract: Nonwoven cellulosic fiber webs including, paperboards and corrugated paper board, etc., are described containing a barrier layer that can act both as a barrier to the passage of a permeant and as a trap for contaminant materials that can arise in new materials or from the recycle of fiber in the manufacture of paperboard. The effective material which acts as a trap or barrier is a cyclodextrin compound, substantially free of an inclusion complex compound. The cyclodextrin barrier layer can be corrugated or sheet laminated with or on the cellulosic web. Alternatively, the cyclodextrin material can be included in a coating composition that is coated on the surface or both surfaces of the cellulosic web after web formation. Further, the cyclodextrin material can be included in a thermoplastic film that can be used as one layer in a bilayer or multilayer laminate containing a cellulosic web.

  • Patent number: 5972807
    Abstract: A film forming, photosensitive, heat-resistant resin composition including a varnish of a polyimide precursor having no photosensitivity in itself, a polymeriziable monomer or oligomer compatible with the varnish and capable of providing a high-heat-resistant polymer upon being polymerized, and a polymerization initiator for the monomer or oligomer. The resin composition is useful for the production of circuit substrates and semiconductor devices for high-density mounting, since it can effectively avoid a reduction of the layer thickness during film formation, and ensures a low cost production process. The pattern formation process using such a resin composition is also disclosed. The polymeric composite having a particles-in-matrix microstructure and the production process thereof are also disclosed.

  • Patent number: 5972264
    Abstract: A method for fabricating fiber-reinforced composite structures, including centrifuge rotors, by resin transfer molding (RTM) is disclosed. The method involves loading reinforcing fibers into a mold and then injecting resin into the mold to coat the fibers to form the composite structure. Two types of reinforcing fibers are used--fabric preforms at the surfaces of the structure and chopped fibers at the interior of the structure. Also disclosed is a fiber-reinforced composite structure comprising a skin layer of reinforcing fabric, chopped fibers distributed throughout the interior of the structure, and epoxy resin that binds the fabric and chopped fibers together into a fiber-reinforced composite structure. The resin transfer molding method is especially useful for fabricating composite centrifuge rotors.

  • Patent number: 5955386
    Abstract: An open weave, air permeable fiber pad is formed from a plurality of compressed, interlocked fiber strands. A non-uniform, three dimensional grid of spaced apart, expandable graphite particles are secured at randomly spaced apart intervals to individual fiber strands with a particle distribution density sufficient to form a barrier to air flow through a defined area of the fiber pad when exposed to a source of heat causing the expandable graphite particles to be converted from their normal volume to a heat-activated, substantially expanded volume.

  • Patent number: 5786280
    Abstract: Carpet material with at least a proportion of uncleaned used carpets is shredded to form a fiber-like wooly mass. The carpet material contains a thermoplastic binder with a low melting point, for example polypropylene, which can be derived from the used carpets or be added. Furthermore, a duroplastically hardening binder, for example phenolic resin, is added to the carpet material. The carpet material is compressed to form the molded part or panel with these two binders, at a temperature which lies above the plasticizing point of the thermoplastic binder, but below the plasticizing point of any other thermoplastic components of the carpet material.
