摘要： A method disclosed herein includes packaging and de-packaging a part. The part is packaged by placing the part adjacent to a shape memory polymer (SMP) while the SMP is in a permanent shape. The SMP is heated to a temperature above a switching temperature of the SMP, and a force is applied to the heated SMP such that it conforms to i) a shape of the part and/or ii) a desired shape for packing the part, thereby changing the SMP from the permanent shape into a temporary shape. The SMP is cooled to a temperature below the switching temperature to set the SMP into the temporary shape. The part is de-packaged by heating the SMP to a temperature above its switching temperature, thereby reverting the SMP from the temporary shape into the permanent shape and releasing the part. The part is removed from the SMP in the permanent shape.

摘要： A one-piece fiber reinforcement for a reinforced polymer is described. In an embodiment, a one-piece reinforcement is fabricated by first assembling an interior randomly oriented fiber layer between two exterior aligned fiber layers. With all layers in face to face contact, a preselected number of fibers from the aligned layer is conveyed out of its aligned layer and threaded into at least the random fiber layer so that the conveyed fibers engage and mechanically and frictionally interfere with the random fibers. The fibers may be conveyed from one aligned layer to the other for yet greater interference. The interfering fibers serve to secure and interlock the layers together, producing a one-piece reinforcement which, when impregnated with a polymer precursor, shaped and cured may be incorporated in a polymer reinforced composite article.

摘要： Magnesium alloy tube members have the potential to reduce weight in automotive vehicle body structures and other applications but they tend to fragment and fail under compressive stress loads applied end-to-end along the longitudinal axis of the tube. It is found that, when the outside surface of the tube is tightly wrapped with fibers (for example, glass fibers or other suitable fibers) and, optionally, resin bonded to the tube surface, the capacity of the magnesium alloy tube to withstand and absorb compressive loads is greatly increased.

摘要： One method of forming a part includes deforming a shape memory polymer from a permanent shape into a temporary shape, where the permanent shape of the shape memory polymer is a predetermined part shape and the temporary shape is a shape larger than the predetermined part shape. The shape memory polymer in each of the permanent shape and the temporary shape defines a cavity therein. The method further includes introducing a molding material into the cavity of the shape memory polymer, and reverting the shape memory polymer back into its permanent shape. Other methods for forming the part are also disclosed herein.

摘要： A method for making a preform includes creating a pressure differential between an inside and an outside of a perforated shape memory polymer mandrel in its temporary shape. The pressure differential is such that pressure outside the perforated shape memory polymer mandrel is greater than pressure inside the perforated shape memory polymer mandrel. The perforated shape memory polymer mandrel has i) a predetermined preform shape as the temporary shape and ii) a shrunken shape as its permanent shape, wherein the shrunken shape is configured such that it is removable from the predetermined preform shape. The method further includes depositing, as the pressure differential is maintained, at least one material onto a surface of the perforated shape memory polymer mandrel. The at least one material is set in the predetermined preform shape, thereby forming the preform.

摘要： A process for molding a composite unipolar plate for a fuel cell stack that increases the strength of a header region of the plate. High strength, non-conductive prepeg inserts are positioned within the mold that are shaped to the configuration of the header region, including the openings that define the various inlet and outlet manifolds. A bulk molding compound charge is positioned in the mold and pressed under high heat so that the bulk molding compound disperses in the mold, and covers the prepeg inserts so that the prepeg inserts are cured to the bulk molding compound.

摘要： A segmented tube formed of a magnesium-based alloy and wrapped or jacketed with a reinforcement to apply a restraining force on the external surface of the tube for resisting fragmentation of the tube by the compressive force applied to the end of the tube serves as a structural member for receiving a compressive stress applied to an end of the tube and acting along the axis of the tube toward the opposing end of the tube. The magnesium alloy tube is comparatively light, and the segmented and wrapped or jacketed tube has an increased capacity to absorb compressive forces. The tubes are useful as components of automotive vehicles.
