    Abstract: An apparatus and method are provided to improve a cutting reliability, to facilitate automation of the connection of wires and to allow for a reliable detection of wire joints. Ends of wires (a, a′) to be connected along their longitudinal directions are linearly placed, and a tape (t) is wound over and around the both wire ends. An adhesive layer of the tape is faced up, and the tape (t) is wound as the wire ends are rolled, thereby connecting the wires (a, a′). Since the tape displays a strong tear resistance in its longitudinal direction, the wires are strongly connected. The tape may contain reinforced fibers to display a stronger tear resistance. The wires (a, a′) are rolled by being held between plates (11, 33) and moving the plate (33) with respect to the plate (11). The tape (t) is placed on an auxiliary base plate (12) and is wound by the rolling movement of the wires (a, a′). The plate (33) is moved back after winding of the tape (t) to untwist the wires (a, a′).

    Abstract: Melt blown or spun bond nonwoven webs are formed by flowing fiber-forming material through a die cavity having a substantially uniform residence time and then through a plurality of orifices to form filaments, using air or other fluid to attenuate the filaments into fibers and collecting the attenuated fibers as a nonwoven web. Each die orifice receives a fiber-forming material stream having a similar thermal history. The physical or chemical properties of the nonwoven web fibers such as their average molecular weight and polydispersity can be made more uniform. Wide nonwoven webs can be formed by arranging a plurality of such die cavities in a side-by-side relationship. Thicker or multilayered nonwoven webs can be formed by arranging a plurality of such die cavities atop one another.

  • Patent number: 6533882
    Abstract: In one general aspect, the invention involves applying a chemical treatment to fibers, such as reinforcing fibers suitable for making a composite article, so as to size and/or preimpregnate the fibers. The chemical treatment has a relatively low viscosity and is substantially solvent-free and non-radiation curable. Heat energy may be employed to lower the viscosity and improve the wetting ability of the applied treatment and/or to increase the molecular weight of, or otherwise cure, the treatment with essentially no generation of solvent vapor. The treated fibers are used to form a composite strand, which may be subsequently processed in-line or off-line into a composite article having fibers disposed in a polymeric matrix. Another general aspect relates to encased composite strands, in thread or pellet form, and to wire-coating methods and apparatus for making them. The strands are moldable into fiber-reinforced thermoplastic composite articles.

Generally the increase in width is sufficient to be economically significant, e.g., to reduce costs of web manufacture.

  • Publication number: 20020197466
    Abstract: The present invention is to provide a base material for a laminate having a high strength, reduced thickness, and light weight. In the present invention, a base material is prepared by incorporating a thermosetting resin binder into a non-woven fabric of para-aramid fibers prepared by a wet type paper making, and then heating a plurality of the resultant non-woven fabric sheets under pressure. The non-woven fabric sheet comprises 95 to 70 mass % of the para-aramid fibers and 5 to 30 mass % of the thermosetting resin binder.

  • Publication number: 20020182954
    Abstract: A composite fabric for use in reinforcement of cementitious boards and similar prefabricated building wall panels. The fabric includes an open mesh first component of continuously coated, high modulus of elasticity strands and a nonwoven second component fabricated from alkali resistant thermoplastic material. The high modulus strands of the first component are preferably bundled glass fibers encapsulated by alkali and water resistant thermoplastic material. The composite fabric also has suitable physical characteristics for embedment within the cement matrix of the panels or boards closely adjacent the opposed faces thereof. The reinforcement provides long-lasting, high strength tensile reinforcement and impact resistance for the panels or boards. The reinforcement also enables the boards to have smooth outer faces suitable for painting, papering, tiling or other finishing treatment.

  • Publication number: 20020156449
    Abstract: The present invention relates to a method of securing an elastic band (13) between two material layers (14) which consist at least partially of meltable material. According to the invention, the elastic band is provided with perforations in the form of holes and/or slots. The band is placed between the two material layers and the layers are bonded together through the perforations by melting or fusing the layers together at locations opposite the perforations. The invention also relates to an elastic band which has been affixed in this manner and to a diaper which includes such a band.

  • Publication number: 20020144767
    Abstract: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure. The upper and lower skins and the core are pulled automatically through tooling where the skin material is wetted-out with resin and the entire composite laminate is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine that deposits “groupings of fiber filaments” at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that a extension of each “grouping of fiber filaments” remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station.

  • Patent number: 6454893
    Abstract: Slits of precisely controlled length are cut in a layer of material having collimated fibers. Each slit begins at a defined coordinate point and proceeds diagonally at an acute angle relative to the axial direction of the fibers. Subsequent slits are initiated at coordinate points relative to the starting coordinate point of the previous slit. The region of fibers located above and below each slit are referred to as upper and lower fiber bands, respectively. The lower bands are substantially aligned in a zonal band that runs perpendicular to the lengths of the fibers. The location of the beginning coordinate point for each slit defining a zonal band is defined by adding a random length dimension to a previous starting coordinate point. The maximum length of the cut fibers may be determined in accordance with the intended application and process.

    Abstract: Carbon nanotube structures which enhances handling of carbon nanotubes, enabling them to be applied in a wide variety fields such as electronic devices, functional materials, and structural materials containing carbon nanotubes, and a method for producing them are provided. A method for manufacturing carbon nanotube structures includes the step of forming liquid bridges of a liquid at gaps among plural objects and/or at plural gaps among portions of an object. The plural carbon nanotubes are dispersed in the liquid and linked together, then arranged structurally to the liquid bridges, and the carbon nanotube structures are manufactured in this way.
