Abstract: A strong, lightweight composite material having beneficial flexing characteristics is made using an unique reinforcement material (10). The reinforcement material comprises a fabric incorporating glass rovings (14) with graphite tows (12) in an architectural combination that retains the properties of both materials. Composite structures made using this reinforcement material with a thermosetting or thermoplastic matrix are extremely lightweight, with desirable anisotropic flexing properties. The finished composite structure is extremely useful as an arch support in a shoe to absorb and distribute the forces generated by walking. In distributing forces on the foot such a support will provide the desired stiffness along the longitudinal axis while allowing increased flexibility along the transverse axis.

Abstract: Electrically conductive polymeric compositions suitable for fabricating devices for safely transporting volatile chemicals and fuels are disclosed. The electrically conductive polymeric compositions include at least one matrix polymer and an electrically conductive filler material incorporated in the matrix polymer in an amount sufficient to provide the conductive polymeric composition with an electrical conductivity of at least 10 S/cm. The electrically conductive filler material is intrinsically conductive polymer coated carbon particles. The coating of intrinsically electrically conductive polymer provides a protective shield against loss of particle conductivity and contributes to the overall conductivity of the filler material.

Abstract: Electrically conductive compositions of carbon particles having thin coatings of conductive polymer are disclosed. The thin coatings of conductive polymer electrically interact with each carbon particle and protect the carbon particles from conductive failure. Because the conductive compositions of coated carbon particles maintain their conductive characteristics even after long term exposure to chemicals, they are useful as filler materials in polymer compositions utilized to fabricate chemical delivery devices.

Abstract: Thermoplastic honeycomb capable of formation by expansion of a compacted ribbon stack and of repeated dips in resin solution to form densified honeycomb panels is prepared by impregnating a fiber web with a thermoplastic material which has a soluble form and an insoluble form, and is readily converted from the former to the latter. Poly(amide-imide)s are an example of a suitable resin. The invention is particularly useful in forming compacted ribbon stacks of resin-impregnated glass fiber, expanding the stacks at an elevated temperature to a partial expansion sufficient to expose the cell interiors, then dipping the partially expanded stacks in resin solution, removing the solvent from the resulting film and curing the film, then expanding the stacks further at an elevated temperature to their full expansion, following by further dips to the final desired density.

Abstract: Polyethersulfone is densified by preparation of a homogeneous paste with a semi-solvent, which may be drawn off by heating and vacuum, from an emulsion prepared from the paste. The resulting PES is substantially densified, with a reduced surface area. The densified PES can be added in significant amounts to thermosetting resin preparations, without a substantial increase in viscosity.

Abstract: A medical implant useful in the regeneration of soft and hard connective tissue, such as cartilage and bone, which comprises a copolymer of a major amount of epsilon caprolactone and a minor amount of lactide. Where regeneration of bone tissue, in particular, is desired, the copolymer may further include osteogenic material in powdered or particulate form. If soft tissue regeneration is desired, the copolymer may include chopped carbon fiber. A mass of the copolymer, optionally including additives, may be molded by hand by heating the polymer to a temperature of 115-160oF, by, for example, immersion in hot water. The mass is then molded to the void to be filled or shape the regenerated tissue is desired to assume, and implanted in the patient. The mass is gradually replaced by regenerated tissue.

Abstract: A method and apparatus for forming a honeycomb structure (22) in which a plurality of thermoplastic layers (12, 14, 16, 18 and 20) are fused together at selected locations (24). The thermoplastic layers (12, 14, 16, 18 and 20) at each of the selected locations (24) are melted together to form a welded portion which includes first and second exterior surfaces. The welding of the thermoplastic layers (12, 14, 16, 18 and 20) is controlled so that no more than one of the exterior surfaces is melted. This partial melting of one layer prevents undesirable welding to adjacent layers. An apparatus (30) for carrying out the method for welding thermoplastic honeycomb structures is also disclosed.
