Abstract: An exterior automotive quality paint coat is laminated to the surface of a plastic car body member of panel. A dry paint transfer film is first laminated to a relatively thin semi-rigid thermoformable resinous backing sheet. The backing sheet side of the resulting laminate is then laminated to a relatively thick thermoformable substrate sheet comprising the same or a compatible polymeric material. The two sheets are joined by extruding the thick substrate sheet and using the heat of extrusion to then laminate the thin backing sheet to the thicker extruded substrate sheet. The resulting thick sheet laminate is then thermoformed, preferably by first heating the laminate to a forming temperature, followed by vacuum forming the laminate to a three-dimensional shape of the finished automotive part, such as a facia, ready to put on a vehicle.

Abstract: This invention is a rapid low-cost technique for manufacturing thick high-performance carbon and ceramic composites in the form of uniformly densified near-net shaped structures. This is accomplished by impregnating composite preforms with low-viscosity wetting monomers which undergo polymerization followed by pyrolysis reactions in the preform ultimately creating ceramic and/or carbon matrices. Since the monomers possess low-molecular-weight they have low viscosities. Thus, if they wet the fiber and partially-densified preform they can easily impregnate even the smallest pores. Once inside the preforms, polymerization of the monomers is then initiated, resulting in a liquid matrix-precursor of the high molecular weight needed to produce a superior matrix (upon pyrolysis) with high efficiency.

Abstract: A product in which at least a portion of the product has a nanocrystalline microstructure, and a method of forming the product. The method generally entails machining a body in a manner that produces chips consisting entirely of nano-crystals as a result of the machining operation imposing a sufficiently large strain deformation. The body can be formed of a variety of materials, including metal, metal alloy and ceramic materials. Furthermore, the body may have a microstructure that is essentially free of nano-crystals, and may even have a single-crystal microstructure. The chips produced by the machining operation may be in the form of particulates, ribbons, wires, filaments and/or platelets. The chips are then used to form the product. According to one aspect of the invention, the chips are consolidated to form the product, such that the product is a monolithic material that may contain nano-crystals.

Abstract: A dynamic reimageable document or electric paper can be formed from ordinary substrates such as paper, transparencies or fabric by printing of microencapsulated Gyricon beads onto one or more discrete surface areas of the substrate. The substrate can include both fixed print regions formed by conventional fixed ink processes and dynamic reimageable regions formed by the Gyricon beads. The Gyricon beads are preferably bichromal and of contrasting colors, such as black/white so as to be changeable to display two states by selective application of electromagnetic force to the beads. By providing bichromal beads in differing color combinations, such as red/white and black/white, a multi-colored document can be achieved in which various fields of the document, representing text, images or graphics, may be in differing colors. Moreover, operations to perform both imaging or erasure can act on the discrete reimageable regions so that the versatility of the electric paper can be enhanced.
