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.

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： A porous bi-layer separator composed of a first layer with a contacting array of non-conducting particles overlaid with a second layer of a microporous polymer layer, may be fabricated on the electrode surface of the anode of a lithium-ion battery to form an integral electrode-separator construction. The bi-layer separator may prevent development of a direct electronic path between the anode and cathode of the battery while accommodating electrolyte solution and enabling passage of lithium ions. Such an integral separator should be mechanically robust and tolerant of elevated temperatures. Exemplary bi-layer separators may be fabricated by sequential deposition of solvent-containing slurries and polymer solutions with subsequent controlled evaporation of solvent. The elevated temperature performance of lithium-ion battery cells incorporating such integral electrode-bi-layer separators was demonstrated to exceed the performance of similar cells using commercial and experimental single layer polymer separators.

摘要： A porous polymer battery separator is provided that includes variable porosity along its length. Such battery separators can increase the uniformity of the current density within electrochemical battery cells that may normally experience higher current density and higher temperatures near their terminal ends than they do near their opposite ends. By disposing a variable porosity separator between the electrodes of an electrochemical cell such that its terminal end has a lower porosity than its opposite end, the transport of ions, such as lithium ions, through the separator can be more restricted in normally high current regions and less restricted in normally low current regions, thereby increasing the overall uniformity of current density within the battery cell. Variable porosity battery separators may be produced by a dry-stretching process or by a wet process. These processes may include forming a polymer-containing film, producing a uniform distribution of pore sites within the film, and reforming the polymer-containing film to a uniform thickness.

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 medical cast and methods of using the same are disclosed. The method of making includes providing a shape memory polymer (SMP) in a permanent shape which corresponds to a limb's general shape but has a diameter smaller than the limb's diameter. The SMP is converted from the permanent shape into a primary temporary shape, which has a diameter larger than both a diameter of the permanent shape and a diameter of the limb. The limb is at least partially surrounded with the SMP in its primary temporary shape. The SMP is then heated, which causes the primary temporary shape to i) attempt to revert to the permanent shape, and ii) conform to a secondary temporary shape having a diameter smaller than that of the primary temporary shape and larger than that of the permanent shape. The SMP in the secondary temporary shape conforms to the limb.

摘要： Laminated metallic sheets which comprise an interior layer of a viscoelastic polymeric compound sandwiched between outer layers of metallic sheet may exhibit enhanced properties through modification of the viscoelastic phase. In a first embodiment the elastic modulus of the viscoelastic polymeric compound may be reduced by incorporating voids, bubbles or pores within the compound. These voids which may be introduced by introduction of polymeric microspheres are effective in reducing the internal stresses induced in the laminate by temperature changes. In a second embodiment, coating the microspheres with an electrically-conductive layer may be effective in enabling resistance spot welding of such laminated materials.
