Abstract: An abrasion resistant garment and method of producing same. A garment that is highly ventilated while providing abrasion protection for a wearer during a slide, as for instance that may occur during a fall from a motorcycle. A material is produced wherein abrasion-resistant, low sliding friction, beads are held within a matrix of high-tensile strength, abrasion-resistant, cords. The beaded matrix within the garment can be augmented with layers to form a lining and exterior layers to enhance visibility. The force of a sliding rider is retained over the beaded matrix, away from the road surface. Under abrasive sliding friction, the beads additionally rotate to an extent which tightens the cord matrix and thereby helps constrain the skin surface of the wearer from making contact with the roadway surface.

Abstract: A method and apparatus for manufacturing fiber-reinforced, composite materials relies on one or more processes improving over conventional forming, filling, and processing techniques. A homogeneous resin-stitching process provides for resin stitching for using only 5-20 percent of the rovings in a preform as wetted rovings, cured to maintain a stitching together of the structure. A resin-packet transfer process provides infusion of resins from directly beside a wall of a preform, rather than passing resins throughout the longitudinal length of fibers in a perform. A cyclic vacuum bagging process alternately applied over pressure and outside vacuum to a vacuum bag process, thus relieving pressure, and later, optionally, applying pressure to improve structural strength. Relieving pressure tends to improve (reduce) porosity.

Abstract: In order to provide wider biaxially-stretched geogrids having high primary direction (PD) strength, crotch-forming zones of a starting material which is at least 2.0 mm thick have protuberances (6). On strectching, PD orientation passes right through the junction (27) but the protuberance (6) causes the orientation ratio of the crotch edge to decrease significiantly as orientation enters the central part of the crotch edge. After a secondary direction stretch of at least about 1.5:1, the thickness of the central part of the crotch edge is not reduced by more than about 20%. The stretching does not reduce the thickness of any point along notional ridge lines (31) to such an extent that the ratio of finished thickness to starting thickness at that point mid-point. In the biax geogrid (25), the junction mid-point is significantly thicker than the PD is less than about 80% of the ratio of finished thickness to starting thickness of the junction strand mid-point.
