摘要： The application relates to a process for forming a nonwoven composite. The process includes forming a lofty nonwoven layer, obtaining a thermoplastic polymer, and applying the thermoplastic polymer to the second surface of the nonwoven layer, where the thermoplastic polymer is in the form of a molten polymer, semi-molten polymer, or solid film. Next, pressure and optionally heat is applied to the nonwoven layer and thermoplastic polymer, where the thermoplastic polymer and the second surface of the nonwoven layer are subjected to a textured surface forming a plurality of peak regions and a plurality of valley regions in the second surface of the nonwoven layer and embedding a portion of the primary fibers from the nonwoven layer into the thermoplastic polymer within the valley regions. The thermoplastic polymer is cooled forming a thermoplastic film and the nonwoven layer which together form the nonwoven composite.

摘要： The composition comprises a mixture of: i) poly(L-, D-lactide) homopolymer and, optionally, poly(ε-caprolactone) homopolymer, and ii) poly(L-lactide) and poly(ε-caprolactone) diblock copolymer, where said copolymer has a molar mass of the L-lactide block of 20,000 g/mol to 200,000 g/mol and a molar mass of the ε-caprolactone block of 10,000 g/mol to 100,000 g/mol, with the molar ratio between the L-lactide block and the ε-caprolactone block of 2:1. The invention also refers to the nanostructured material obtained from this composition that is characterized by a nanostructure of two mutually self-assembled phases, one phase being formed by a polymeric matrix of poly(L-, D-lactide) units and the other phase by poly(ε-caprolactone) units self-assembled with the matrix and also its use for the manufacture of a plastic article in the form of a transparent film or thin sheet.

摘要： A shape memory polymer thermal interface material (SMP TIM) pad may be deformed to a deformed SMP TIM pad. The deformed SMP TIM pad may be mated to a first surface of a computing chip. A heat dissipating structure may be mated to the deformed SMP TIM pad opposite of the first surface of the computing chip. A loading force may be applied to the SMP TIM pad. The deformed SMP TIM pad may be heated to a reformation temperature. The heat dissipating structure may be fastened to the computing chip using one or more fasteners.

摘要： A method of processing a continuous sheet of polymer material. The method includes routing the continuous sheet of polymer material from a first spool and along at least a first heated roller and a second heated roller, heating the continuous sheet of polymer material to a first temperature on the first heated roller and the second heated roller, and controlling a rotational speed of the first heated roller and the second heated roller such that the continuous sheet of polymer material is stretched when routed from the second heated roller to the first heated roller.

摘要： A method for impregnating a fibrous material with a curable resin to form a prepreg is disclosed. The method includes conveying a web material through at least one moving pressure nip formed between a moving pressure roller and a moving supporting surface, wherein the moving pressure roller and the moving supporting surface travel at different velocities relative to each other resulting in a relative velocity between the web material and the pressure nip. The at least one moving pressure nip travels in the same direction as the web material while applying sufficient pressure to compress the web material and to affect impregnation of the fibrous material with the curable resin. Also disclosed is a system for implementing the disclosed impregnation method.

摘要： The disclosure provides a system of thermoset shape memory poly(urea-urethane) with permanent reshaping property and its application. The breakthrough of the present invention is that the reshaping temperature can be tuned in a wide range by incorporation of urea bonds into the polymer network. The permanent shape for shape memory poly(urea-urethane) can be repeatedly and cumulatively reshaped at certain temperature, largely facilitating the fabrication of complex structures.

摘要： The present invention relates to an external cooling system for a molten film tube produced by a blown film tubular extrusion process, comprised of one or more enclosures with one or more respective cavities that directly receive a portion of cooling gas emanating from one or more associated cooling elements. Each enclosure includes a port containing a variable exhaust device and optional flow buffer, acting to maintain a pressure differential between the cavity and an adjacent inside volume of the molten film tube, adjustable to optimize molten film tube stability cooling element efficiency and spaced apart dimension between cooling elements. Additionally, at least one cooling element is provided, comprised of a divergent cooling element with a divergent cooling interface containing a cooling gas deflector spaced adjacent to the molten film tube and providing an expelled cooling gas.
