    Abstract: A method is presented for making a composite material from strips comprising longitudinal fibres and a binder or resin, which material comprises a number of layer assemblies one on top of the other. Each layer assembly comprises m sets (with m at least 2) of parallel strips each extending in a different direction, Each layer assembly is manufactured by successive steps of depositing groups of parallel strips according to a well defined pattern (without longitudinally interweaving strips with previously deposited strips). Before completing a layer assembly, with the exception of the last layer assembly, by depositing its last group of parallel strips, the first group of parallel strips of the following layer assembly is already deposited. A composite material manufactured with such a method is presented too.

  • Publication number: 20100305687
    Abstract: A mat having a highly uniform porosity distribution is produced by consolidating 15 or more layers of melt blown webs (or the like) having different orientations. Control over the porosity is provided by using webs that exhibit a narrow, unimodal distribution of fiber diameters over the bulk of its distribution, such as in the top 80%. A compliance of the mats can be chosen by selecting a number and orientation of the webs. It is thus possible to produce mats that are good candidates for vascular grafts, for example. The uniformity of the porosity within the range of 6 ?m to 30 ?m permits seeding of the vascular graft with endothelial and smooth muscle cells. The mats have the demonstrated ability to retain, and support growth of, smooth muscle cells and endothelial cells.

  • Publication number: 20080268190
    Abstract: The present invention provides degradable extruded netting. The netting comprises a plurality of oriented interconnected strands that intersect during extrusion. At least some of the strands include a degradable composition comprising a stiffening agent, a degradable material and a crystallinity inhibiting agent. In some embodiments, the stiffening agent comprises a polylactic acid polymer, the degradable material comprises a polyester degradable plasticizer, and the crystallinity inhibiting agent comprises a starch-based polymer. In certain embodiments, the degradable composition may comprise 10 to 70 weight percent polylactic acid polymer, 15 to 75 weight percent polyester degradable plasticizer, and 5 to 30 weight percent starch-based polymer. In other embodiments, the degradable composition may further comprise a friction reducing additive.

  • Patent number: 7442188
    Abstract: An elongate elastic member is secured to a substrate to form an elastic composite. The elastic member extends along an elastic axis between a first location on the substrate and a second location on the substrate spaced longitudinally from the first location. At least a portion of the elastic axis is generally non-parallel to the longitudinal axis of the substrate. The elastic member crosses its elastic axis at least twice as it extends along the elastic axis, with the elastic member crossing itself at least once as it extends along the elastic axis. In another embodiment, the elastic member generally forms a wave pattern which defines a width of the securement path and has at least two different periods along the securement path. In yet another embodiment, the elastic member defines a continuous series of loops wherein each loop defines a closed portion having a generally tear-drop shape.

  • Patent number: 7402536
    Abstract: A bamboo Chair pad that can be manufactured from 100% Anji Mountain bamboo from China. The bamboo is all treated with various protective coatings to add resistance to natural factors including water, sun and dirt. All bamboo chair pads can be manufactured from the harder portions of the bamboo trunk. (Some bamboo are manufactured from the softer fibers of the inside of the bamboo trunk). This portion of the bamboo trunk is not utilized for this invention. The bamboo utilized in the present invention is taken from the harder part of the bamboo trunk to assure maximum endurance and longevity. The lower trunk portion of the bamboo plant is harder and less porous.

  • Patent number: 7371699
    Abstract: A net-reinforced film structure includes a film layer and a netting attached to the film layer having a pattern of netting strands. The netting strands are sealed to an opposing film structure, which may be either a similar net-reinforced film or a standard sheet of film, along a linear seal area. The netting strands in the non-sealed areas of the net-reinforced film structure are free from attachment to the opposing film structure. The netting strands along the linear seal area have a wider cross-section than the netting strands at the non-sealed areas, and this wider cross-section facilitates the sealing process.

  • Patent number: 7329455
    Abstract: A three-ply product includes a particleboard core assembled with a patterned vulcanized fibre sheet or layer on each surface. One of the vulcanized fibre sheets may have a preprinted decorative pattern provided thereon. The other vulcanized fibre sheet may also be decorative, or merely a plain sheet of vulcanized fibre. The product is useful for woodworking applications, and may be processed (i.e., stained, sanded, lacquered, etc.) like a natural wood product. Unlike prior vulcanized fibre processes, the process of making the vulcanized fibre sheets preprints a pattern, in a preprinting process, on the top sheets of cellulose paper plies.
