Abstract: A composite of thermally non-adherent fluoropolymeric and non-fluoropolymeric components is created through the agency of a non-woven, fibrous binder interposed between and portionally embedded into both components. The fibers of the non-woven binder have a substantial portion of their length extending into both components and cross the interface at an angle that is substantially normal to the plane of embedment. The composite possesses good peel strengths of greater than 5 pounds/linear inch between the otherwise thermally non-adherent components.

Abstract: A method for preparing an uncured supported elastomer material includes the steps of: providing a fibrous reinforcement material; providing a layer of uncured elastomer material substantially adjacent to the fibrous reinforcement material; exposing the layer and the fibrous reinforcement to a temperature below a curing temperature and above a flow point of the uncured elastomer material, and a pressure sufficient that the uncured elastomer material flows into the fibrous reinforcement material, so as to provide an uncured supported elastomer material.

Abstract: Articles made from melamine fibers and aramid fibers are dyed at selected conditions and with selected dyes such that the aramid fiber is dyed but the melamine fiber is not.

Abstract: A nonwoven fabric cloth substrate for printed wiring boards containing aromatic polyamide fibers and having a 0.7-1.0 dynamic elastic modulus ratio (E' (250.degree. C.)/E' (30.degree. C.)) and a 0.05 or less loss tangent (Tan.delta.) peak value at 30.degree.-250.degree. C., and a prepreg and a printed wiring board using the nonwoven fabric cloth substrate.

Abstract: The present invention relates to a fibrous base material comprising a primary layer of less fibrillated aramid fibers, synthetic graphite and at least one filler material, and a secondary layer of carbon particles on at least one surface of the fibrous base material for use in a non-asbestos friction material. In certain embodiments, the fibrous base material is impregnated with a phenolic or phenolic-based resin material, including, for example, a mixture of a phenolic resin and a silicone resin to form a friction material having good "break-in" and durability characteristics.

Abstract: The present invention relates to a friction material comprising a fibrous base material primary layer of less fibrillated aramid fibers, synthetic graphite and at least one filler material, and a secondary layer of a mixture of carbon particles and at least one retention aid coated on at least one surface of the primary layer. In certain embodiments, the fibrous base material is impregnated with a phenolic or phenolic-based resin material, including, for example, a mixture of a phenolic resin and a silicone resin to form a friction material having high heat resistance and high friction durability characteristics.

Abstract: Material for antiballistic protective clothing comprising in a single-layer or multi-layer package or laminate at least one layer of a flat structure containing an organic dilatancy agent This flat structure is particularly suited for a trauma package in an antiballistic package. The flat structure with a dilatancy agent results in a significant improvement in the antiballistic effect and, in particular, a reduction in the trauma effect. The material finds special application for bullet-proof and splinter-proof vests and correspondingly for helmets. Moreover, the material of the invention can be used in clothing protecting against impact.

Abstract: The present invention provides a lightweight prepreg having uniform formation, low linear thermal expansion coefficient and good mechanical strength, comprising a porous para-oriented aromatic polyamide film and a thermoplastic resin and/or a thermosetting resin, the porous para-oriented aromatic polyamide film being impregnated with the thermoplastic resin and/or the thermosetting resin, a process for producing the same, and a printed circuit substrate/board using the same.

Abstract: A fiber reinforced composite structure and method for fabricating the composite, are described wherein four sets of mechanically flexible fibers are interwoven in a three-dimensional woven structure wherein each fiber is woven through the structure generally along one of the four directions defined generally parallel to a body diagonal of a cube, and wherein the woven structure is impregnated with polymeric, metallic or ceramic matrix material to form a composite material which is braced against deformation by shear applied in any orientation.

Abstract: A wholly aromatic polyamide staple fiber fabric having excellent insulation and superior dimensional stability at a high temperature and/or a high humidity, includes 70 to 96 parts by weight of a staple fiber web made from a blend of 5 to 30% by weight of m-type wholly aromatic polyamide staple fibers and 70 to 95% by weight of p-type wholly aromatic polyamide staple fibers, and 4 to 30 parts by weight of an organic resin binder incorporated into the staple fiber web.
