Abstract: The purpose of the present invention is to provide a shell laminated structure realizing a further light weight formation of a helmet while improvement for shock absorbing characteristic is assured. There is provided a laminated structure in which either the net-like member or the sheet-like member having many holes is placed at an entire region of the shell having a reinforcing base material or between the laminated layers at a part of the shell in such a manner that the sheet-like member is extended along the layer to which its front and rear surfaces are faced, bitten into the layer and fixed. With such an arrangement as above, a further light weight formation of the shell is realized while a high safety characteristics of the helmet is assured.

Abstract: Biodegradable terephthalate polymers are described comprising the recurring monomeric units shown in formula I: wherein R is a divalent organic moiety; R′ is an aliphatic, aromatic or heterocyclic residue; x is ≧1; and n is 0-5,000, wherein the biodegradable polymer is biocompatible before and upon biodegradation. Processes for preparing the polymers, compositions containing the polymers and biologically active substances, articles useful for implantation or injection into the body fabricated from the compositions, and methods for controllably releasing biologically active substances using the polymers, are also described.

Abstract: A lightweight ballistic resistant rigid structural panel especially for use in aircraft interiors is disclosed. The rigid structural panel is made up of a core layer including a plurality of sheets of flexible, high-tensile strength fabric interleaved with a plurality of sheets of a thermal-fusible film adhesive, and a sheet of cushioning material adhered to the plurality of sheets of flexible, high-tensile strength fabric. Fiber-reinforced face skins are adhered to exterior surfaces of the panel core for structural strength and rigidity. The rigid structural panel is capable of resisting ballistic attack from handguns and like weapons, while maintaining a high degree of strength and rigidity.

Abstract: A protective material comprises in one embodiment a plurality of separate flexible layers, each layer including a plurality of high-strength fibers capable of resisting penetration by a knife or sharp-pointed objects, such as ice picks and hypodermic needles, and a support material, wherein at least part of the fibers are embedded within the support material to restrict relative movement of the fibers therein. The high-strength fibers have a denier of less than or equal to 600.

Abstract: The present invention concerns weaving. In particular, it is a woven material produced using tape-like warp and tape-like weft through the employment of a rotary type shedding device which also functions as a direct specific-weave patterning device and a pick guiding device. The material according to the invention has a constructional constitution of at least some of the warp and weft that is non-homogenous. The invention also relates to a weaving device for producing woven material with tape-like warp and weft, comprising a rotary device, which is capable of producing more than one fabric simultaneously.

Abstract: Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.

Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessarily low permeability levels. Thus, the inventive coated inflatable airbag comprises a film laminated on at least a portion of the target fabric surface wherein the film possesses a tensile strength of at least 2,000 and an elongation at break of at least 180%.

Abstract: Thermosetting polymers and the electrical laminates made therefrom are disclosed. The polymer comprises the cross-linked product of: a) one or more ethylenically unsaturated aromatic monomers, optionally containing a halogenated monomer to impart fire retardation, and b) a vinyl-terminated polybutadiene or butadiene-styrene copolymer containing either a urethane or an ester group. It has been discovered that an unexpected combination of thermal, electrical, and mechanical properties are obtained from the composition recited herein. The composition is ideally suited as a matrix polymer for electrical substrate applications.

Abstract: A laminate wall structure which can be used as an exterior wall in manufactured housing and site built construction is made up of a low density layer having a density of from about one-half pound to three pounds per cubic foot, a second, reinforcing layer laminated to the low density layer and, optionally, a cellulosic layer laminated to the second, reinforcing layer. The low density layer is preferably a foamed polymer layer, the second, reinforcing layer is a polymer fabric, a biaxially oriented polymeric film or a fiberglass reinforced material and the cellulosic layer can be impregnated with an adhesive and/or resin in order to strengthen the laminate structure. This laminate wall structure has a low weight and yet is strong enough to meet wind zone wall diaphragm requirements for housing construction.
