    Abstract: 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.

    Abstract: A ballistic resistant composite material useful in rigid armor applications. The composite material includes at least one consolidated network of high tenacity fibers in a thermoplastic matrix material. The resin is a thermoplastic polyurethane resin that is semi-crystalline at room temperature. The high tenacity fibers have a tenacity of at least about 7 g/d. Prior to consolidation the polyurethane resin matrix material is in an aqueous medium. When dry, the polyurethane matrix material has a tensile modulus (at 100% elongation) of at least about 500 psi (3.45 MPa), a tensile modulus (at 300% elongation) of at least about 500 psi (3.45 MPa), and an ultimate tensile strength of at least about 2000 psi (13.78 MPa). The ballistic resistant composite material has improved ballistic properties.

    Abstract: A helmet shell formed from two types of high tenacity fibers in multiple layers of fibrous materials. The fibrous materials are in the form of layers of fibrous networks in a resin matrix. There are a plurality of each type of fibrous layers. Preferably the outer set of fibrous layers is formed from aramid fibers and the inner set of fibrous layers is formed from high tenacity polyolefin fibers. There may also be employed a third type of fibrous material as an additional set of fibers and used as the outer layers of the helmet shell. The third type of fibrous layers is formed from glass fibers that are also in a resin matrix. The helmet is lightweight, has excellent ballistic resistant properties and is useful for both military and non-military applications.
