摘要:
A copper clad laminate is introduced. Cyclic olefin copolymer fabric functions as a base fabric for manufacturing the copper clad laminate to reduce dielectric constant (Dk) and dissipation factor (Df) of the copper clad laminate. The flame-retarded curing agent included in the resin for use in manufacturing the copper clad laminate is halogen-free and does not cause environmental pollution. The cyclic phosphate structure of the flame-retarded curing agent enhances thermal stability and chemical stability of the copper clad laminate thus manufactured. During the manufacturing process of the copper clad laminate, an annealing process is performed while thermal curing and lamination is taking place to prevent bending otherwise resulting from a difference in thermal expansion coefficient between cyclic olefin copolymer fabric and glass fiber fabric.

Disclosed is to a composite material, a structural element comprised of the composite material, an airplane wing spar and their methods of production. Some embodiments of the present invention include composite materials comprised of multiple layers of arrays of metallic bodies separated by layers of non-metallic material, wherein the orientation of metallic bodies in some metallic layers is structurally complementing to the orientation of metallic layers in adjacent metallic layers. Other embodiments of the present invention include structural elements, such as an airplane wing spar, comprised of the composite material.

摘要:
Impact resistant composites formed from at least one fibrous layer comprising a network of high tenacity fibers and at least one layer of a thin titanium film the composite being resistant to at least one of knife stabs, ice pick stabs and ballistic projectiles. Preferably there are a plurality of such layers and the titanium film layer is disposed between adjacent fibrous layers. Body armor formed from the composites have the desired resistance to knife stabs, ice pick stabs and ballistic projectiles.

摘要:
A heat shield having a thermally conductive body. The material of the body is composed of a fibre composite material, preferably carbon fibre, glass fibre, glass-fibre-reinforced plastic and/or aramide, and layers of a heat-conductive metal. Cooling tubes may be applied to an outer surface of the body, incorporated into an outer fibre layer of the body, and/or formed directly within the outer fibre layer.
摘要:
The invention is a new heat and fire resistant material and an improved wildland fire shelter and kit. The material is made of a woven silica-based cloth layered in several possible combinations with foil and fiberglass cloth layers. The layers can be arranged in a variety of sequences to minimize the thermal radiation to the inside of the material or shelter. However, a foil layer must always be the outermost layer to provide protection from radiant heat and a layer of foil must be present between the interior of the shelter or material and any layer of adhesive to limit accumulation of gases inside the shelter if the adhesive or other substance should break down when exposed to heat. The silica cloth, aluminum foil, and fiberglass cloth may be laminated or sewn together. The shape of the fire shelter is a half cylinder with ¼ sphere at each end. The shelter is contained in an easy-open polyvinyl bag which provides for quick removal and deployment of the fire shelter.
