A frictional power transmission belt includes a tension layer forming a belt back surface, a compression rubber layer to be in contact with a pulley and frictionally engaged with the pulley, and a tension member embedded between the tension layer and the compression rubber layer along a belt length direction. The compression rubber layer has a surface to be in contact with the pulley. At least a part of the surface is coated with a fiber layer via a fiber/resin mixture layer. The fiber/resin mixture layer contains a resin component and heat-resistant fibers having a softening point or a melting point higher than a vulcanization temperature of a rubber forming the compression rubber layer. The fiber layer contains hydrophilic heat-resistant fibers having a softening point or a melting point higher than the vulcanization temperature and does not contain a resin component.

Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and healing to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.

A waterproof membrane includes first and second non-woven layers each having first and second surfaces. A cross laminated film layer is disposed between the first and second non-woven layers. Tie layers are applied between the non-woven layers and the cross laminated film layer. A method of making a waterproof membrane, a method of establishing a waterproof barrier between a substrate and a tile, and a flexible membrane for use in a curvilinear surface are also disclosed.

A composite structural panel for use in bridge structures, and method of manufacturing same, comprises a top panel and a bottom panel separated by and attached to at least one, but preferably a plurality, of structural composite preforms which may be fabricated by a continuous manufacturing process and may be saturated by resin using a continuous wetting process. The composite preforms may take any cross-sectional shape but are preferably trapezoidal. The top and bottom panels may be fabricated from a plurality of layers of woven fabric layers and non-woven fabric layers which are saturated with a resin that is subsequently cured using cure processes known in the art. The composite structural panel of the invention is usable as a flat structural member for use as bridge decking, ramps, trestles, and any application requiring a structural panel.

A composite board comprising (i) a first foam region; (ii) at least one fragile insulating material; and (iii) a second foam region, where said second foam region is substantially devoid of hydrocarbons.

An inflatable cushion comprises an inflatable cushion body. The inflatable cushion body comprises a first region and a second region formed by pressing an upper and a lower fabric layers; the first region and the second region are adjacent; a cavity is arranged in the first region; a sponge is arranged in the cavity; the inflatable cushion body is provided with an air guide part for inflating and deflating the cavity; the second region is evenly provided with transverse sealing lines; the transverse sealing lines separate the second region into mutually communicated inflating cavities; and the second region is provided with a first inflating port for inflation and deflation. By arranging the first region and the second region, the sponge is arranged in the first region and the inflating cavities are arranged in the second region.

An artificial turf contains a damping layer made of a particle foam, a fiber backing, and an artificial grass layer made of single or multiple fibers. The fibers are tied to the fiber backing, forming an artificial carpet of grass. The particle foam and the single or multiple fibers forming the artificial grass layer are each made of a thermoplastic elastomer.

A cover for a cushion includes a first panel, a second panel, and a primary receptacle defined between the first panel and the second panel. The primary receptacle may receive a primary cushioning element, such as a pillow, a pillow insert, or a fill material. At least one of the first panel and the second panel includes a secondary cushioning element. The secondary cushioning element may be defined from a compressible, resilient elastomeric material that defines a plurality of thin interconnected walls that in turn define an array of open cells or columns. Each cell or column may have a hexagonal shape, imparting the array of open cells or columns with a honeycomb appearance. Methods for assembling a primary cushioning element with such a cover are also disclosed.
