    Abstract: A bi-layer, woven geotextile fabric has interwoven first and second layers. The first layer is over and under woven through the second layer in a pre-determined pattern so that the first layer has portions which face a first side of the second layer and portions which face a second side of the second layer. Monofilaments in the warp direction of the first layer have a pre-determined differential heat shrinkage characteristic that is greater than the monofilaments in the warp direction of the second layer. Closed cells defined by the pattern of the over and under weave are disposed on the first and second sides of the second layer. Shrinkage of the monofilaments in the warp direction of the first layer provide for a separation of a portion of the second layer from the first layer at the cells.

The fabrics comprise layers of yarns woven together wherein the yarns further comprise carbon nanotube fibers. These carbon nanotube fibers may be either single-walled or multi-walled carbon nanotubes. The use of carbon nanotube fibers allows the fabrics to insulate, semi-conduct or super-conduct electrical charges. Additionally, the thermal properties of carbon nanotubes allow thermal energy to flow efficiently between the fabric and a heat sink or source. Additional yarns of materials other than carbon nanotubes can be integrated or woven into the fabric to provide other unique properties for the fabric. These fabrics can be layered to form unique garments or structures.

Accordingly, when the wearer's body heat and body odor try to pass through the clothing made from the material, the body heat may smoothly pass through the adsorption layer while the body odor is blocked and filtered out by the activated carbon fiber. Thus, the requirements of hunter clothing may be satisfied. Furthermore, the odors or toxins trying to pass through the adsorption layer may be filtered out, and the requirements of the chemically protective clothing and hunter clothing may be satisfied.

  • Patent number: 5773122
    Abstract: Layered carbon-carbon composites having improved interlaminar tensile strength are disclosed together with a process for making such composites. A metal catalyst is first deposited on a panel comprising a plurality of layers of carbon fiber cloth. The panel is then exposed to a gaseous hydrocarbon in an inert atmosphere at elevated temperature in order to promote the growth of graphite whiskers between the carbon cloth layers.

  • Patent number: 5700743
    Abstract: A structural component which consists of a fiber-reinforced, composite material is provided with a protective coating against erosion. The protective coating includes an adhesion-promoting, intermediate layer on the component, an electrically insulating baked, inorganic lacquer layer for protection against erosion and an electrically conducting covering layer, for protection against lightning strikes. The covering layer consists of a baked and compressed inorganic lacquer and the lacquer of the lacquer layer and of the covering layer is baked on the component below the temperature which causes damage to the structural component or below the softening or decomposition temperature of the component. The protective layer is advantageously used for the external components of propulsion units, such as housings, nose cones or fan blades.

  • Patent number: 5645926
    Abstract: A flexible fire and heat resistant material comprising an intimate mixture of organic intumescent filler and organic fibres adapted to char intensely within the temperature range of 200.degree. C. to 500.degree. C. The added presence of inorganic fibre components enhances the structural integrity of this structure both during char formation up to 500.degree. C. and at higher temperatures up to 1200.degree. C. once char oxidation takes place.
