    Abstract: Inserts of metal in the plastic of a plastic structural element are coated with a coupling layer of fibre-reinforced plastic, which reduces the abrupt change in stiffness and/or coefficient of thermal expansion at the joining interfaces in the metal-plastic composite. By altering the volume fraction of fibres and/or by different orientation of the fibre layers within the coupling layers, a gradual change in the E-modulus and the thermal expansion coefficient are produced, as a result of which abrupt changes in these values at the composite interfaces can be avoided. The sudden change in stiffness between the plastic material and the metal inset also reduced by reducing the stiffness of the insert, which again is achieved by specific choice of shape. Preferred, in particular, is a finger-shaped fanning out of the insert in the plastic material.

  • Patent number: 6610618
    Abstract: The invention pertains to a penetration-resistant material having at least a double layer of fabric composed of two layers of woven fabric which are cross-plied at an angle, characterized in that the fabric is composed of a first set of threads having 3.5 to 20 threads/cm and having a linear density of at least 420 dtex, and a second set of threads having 0.5 to 8 threads/cm and having a linear density of at least 50 dtex, with the second set of threads being transverse to the first set of threads, and wherein the ratio of the linear density of the first set of threads to the linear density of the second set of threads is >4.2, more preferably >7.5. In a preferred embodiment, the first set of threads is warp threads made of p-aramid yarn and the second set of threads is weft threads of polyester yarn, and the ratio of the number of threads/cm of the first set to that of the second set is >1.

  • Publication number: 20030091785
    Abstract: A fabric system for producing at least a woven fabric of controlled modulus or elongation in the MD or warp axis, has a core layer which is the main structural element, and may have one or more woven cover fabrics adhesively bonded with an off axis configuration to one or both sides of the core layer. In a preferred embodiment the core fabric is covered with at least one off axis fabric on both sides. The cover fabrics may also have resin or film top layers laminated or coated on their outside surfaces, for mechanical performance or UV protection or both.

  • Patent number: 6555192
    Abstract: A pressure-sensitive cleaning sheet is disclosed which comprises a substrate, a pressure-sensitive adhesive layer formed on one or both sides of the substrate, and a porous screen disposed on the pressure-sensitive adhesive layer. The cleaning sheet is substantially non-tacky when the cleaning sheet surface is kept in a non-pressed state, and exhibits tackiness when the cleaning sheet surface is kept in a pressed state. Also disclosed are a method of using the cleaning sheet, an image-forming material having a cleaning part, and a method of cleaning an image-forming apparatus. These are useful for the cleaning of, e.g., the magnetic reading parts and magnetic-card transport parts of apparatuses accepting various magnetic cards and the thermal heads and/or transport rollers of various recording apparatuses.

  • Patent number: 6482497
    Abstract: A method and apparatus for manufacturing fiber-reinforced, composite materials relies on one or more processes improving over conventional forming, filling, and processing techniques. A homogeneous resin-stitching process provides for resin stitching for using only 5-20 percent of the rovings in a preform as wetted rovings, cured to maintain a stitching together of the structure. A resin-packet transfer process provides infusion of resins from directly beside a wall of a preform, rather than passing resins throughout the longitudinal length of fibers in a perform. A cyclic vacuum bagging process alternately applied over pressure and outside vacuum to a vacuum bag process, thus relieving pressure, and later, optionally, applying pressure to improve structural strength. Relieving pressure tends to improve (reduce) porosity.

  • Patent number: 6265047
    Abstract: A low-stretch, flexible composite, made of one or several sections, particularly useful for making a sail (2), includes first and second polymer films (52, 62) with discontinuous, stretch-resistant segments (16) therebetween. The segments extend generally along the load lines (17) for the sail. The segments have lengths which are substantially shorter than corresponding lengths of the load lines within each section. The ends of the segments are laterally staggered relative to one another. Mats (20) of generally parallel mat elements can be used as the segments. The mat elements typically include discrete multifiber yarns (24, 26) and/or a fiber array (22), typically created by pneumatically laterally spreading apart the fibers of an untwisted multifiber yarn (32). A laminating assembly includes first and second flexible pressure sheets (66, 68), defining a sealable lamination interior (82) containing the material stack (64) to be laminated, housed within an enclosure (90).

  • Patent number: 6165586
    Abstract: A flat strip (1) including at least one layer (2) of longitudinal filamentary rovings (3), and means for assembling said filamentary rovings. The assembly means comprise a bonding material (5) and retaining means (4) surrounding and clamping said layer (2). The longitudinal filamentary rovings (3) are agglomerated into a relatively flat strand with a substantially rectangular cross-section, and each filamentary roving (3) has a predetermined average compactness of at least 60%. The retaining means (4) consist of a flat tubular sheath including elements (7) extending transversely to the longitudinal direction of said filamentary rovings (3). Said strip is particularly useful for reinforcing ducts used in the oil industry.

  • Patent number: 6054205
    Abstract: The invention provides a glass fiber facing sheet for engineered surfaces such as cement boards which reduces the pitting associated with open mesh glass scrims. The glass fiber facing sheet comprises an open mesh glass scrim having a plurality of intersecting continuous multifilament yarns which are bonded at their crossover points to provide dimensional stability to the scrim. A melt blown polymer web is preferably joined to one face of the glass scrim and covers the mesh openings in the scrim. The opposed face of the scrim defines an exposed grid profile surface which is available for mechanical interaction between the scrim and the cementitious slurry used in cement boards. In cement boards, the glass fiber facing sheet of the present invention is preferably mechanically integrated into a surface portion of the cement core along the exposed grid profile of the scrim.
