Abstract:
Inflatable airbag (26) for a vehicle (18) which is deployed in the event of an accident involving the vehicle (18) to provide protection for an occupant of the vehicle (18) includes a plurality of ribbons (32) coupled together to define an enclosed, fluid-retaining space and a layer of film (44, 46) laminated on at least one of an outer side of the woven ribbons (32) and an inner side of the ribbons (32). The ribbons (32) may be made from polypropylene, polyethylene, polyester or polyamide and the layers of film (44, 46) may be made from polyethylene, polyurethane, polyester or polyamide. The ribbons (32) and layers of film (44, 46) may be made of the same or different materials.
Abstract:
A material is provided that includes a first section for storing energy and a second section for releasing energy received from the first section in which the energy is preferably electrical energy that is used for one from among heat dissipation, heat generation, light emission and powering of an electric circuit. Ideally the material includes a third layer adapted to collect energy and convert the energy to electrical energy for storage in the first section. A fourth protection section is provided on at least one side of the material. The material can be formed of woven strips, laminated sections, or in coaxial sections that are woven together to form a flexible fabric material having at least one characteristic from among breathability, wickability, moisture resistance, moisture-proof, and stretchability.
Abstract:
Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally. The doubled warps and wefts comprise disconnected tapes. Such separateness of constituent tapes of doubled warp and weft tapes enables them to be slid/slipped relative to each other by pulling longitudinally and laterally without causing any alteration in the woven structure. These novel fabrics solve the problem of uneven fibre distribution and orientation arising from crumples/wrinkles due to compression and stretches due to extension, at the inner and outer sides respectively, when tape- woven fabrics are curved into shapes. Further, by using doubled warps and wefts fabrics with relatively flat/planar sections and thicker/raised wide rib sections can be also created that resemble a bit like a profiled material in its cross-section. Other fabrics like those comprising slant/oblique weft tapes, shaped warp and weft tapes, formed shape within its body are also producible.
Abstract:
Electrically conductive tape yarns (1, 9) of two or more layers (3, 5, 11, 13, 15) comprising thermoplastic polymer resin and electrically conductive particles, a process for making such tapes and fabrics (17) comprising such tape yarns are disclosed.
Abstract:
A thermoplastic composite material comprising a molecularly-oriented thermoplastic polymer base having at least one thermoplastic surface polymeric layer compatibly bonded to said polymer base by molecular interspersion between the contiguous surfaces of the adjoining base and surface layers, and said surface polymeric layer having a softening temperature lower than that of the polymer base.
Abstract:
The invention relates to a process to make films and tapes from ultrahigh molecular weight polyethylene (UHMWPE) in the solid state. The films and tapes according to the invention have an improved thickness whereby the coefficient of variation of the thickness of the film of at most 6%.
Abstract:
La présente invention concerne un matériau intermédiaire composé d'un ensemble de rubans entrecroisés avec entrelacement caractérisé en ce qu'au moins certains des rubans, et de préférence tous les rubans, nommés rubans voilés, sont composés d'une série de fils ou filaments de renfort qui s'étendent selon une direction parallèle à la longueur du ruban pour former une nappe unidirectionnelle qui est associée sur chacune de ses faces à un non-tissé en fibres thermoplastiques, ces deux non-tissés assurant la cohésion dudit ruban voilé grâce à leur caractère thermoplastique, un procédé de fabrication mettant en ouvre un tel matériau pour la réalisation de pièces composites, ainsi que les pièces composites obtenues.
