    摘要： Plastic pipes, such as high density polyethylene plastic pipes, useful for distributing natural gas and which have improved impact resistance and burst strength. The plastic pipe has an inner and an outer surface, with the inner surface defining a channel for conveying natural gas and the like. A fabric overlies the outer surface, preferably in a helical wrap. The fabric is formed of high tenacity polyolefin fibers, preferably polyethylene and/or polypropylene fibers. The fabric provides the pipe with improved burst strength and impact resistance. The pipe can be used to transport natural gas under low pressure or higher pressures.

    摘要： Ballistic resistant materials having improved strength and lighter weights. More particularly, improved ballistic resistant fabrics produced from drawn, high modulus fibers having a reduced fiber diameter and improved physical strength properties, without changing other properties such as fiber chemistry, binder resin type and binder resin content. The fabrics incorporate low denier per filament monofilament fibers, low denier per filament multifilament fibers, or a combination of low denier per filament monofilament fibers and low denier per filament multifilament fibers in a specialized fabric construction to form fine fiber layers and fabrics having enhanced strength and fiber areal density without altering the fabric weight, or having reduced fabric weight without a corresponding reduction in ballistic performance.
