摘要:
Poly(ethylene tetrafluoroethylene) (ETFE) polymers having an average molecular weight of at least 300,000 g/mol and a melt enthalpy of at least 57 J/g are provided. The ETFE polymer may include at least one additional comonomer. The ETFE polymer is used to form a porous tape or membrane that has a node and fibril structure. A porous ETFE tape may be formed by lubricating the ETFE polymer and subjecting the lubricated polymer to pressure at a temperature below the melting point of the ETFE polymer. Optionally, the ETFE tape may be expanded at a temperature below the melting temperature of the ETFE polymer to form an expanded ETFE membrane. Alternatively, the ETFE polymer may subjected to heat and pressure without the addition of a lubricant to form a dense preform. The dense preform may be subsequently slit in a length direction and stretched to form a dense ETFE fiber.

A system and method for a moldable wallet. A moldable wallet has a clam shell shape with a top shell coupled to a bottom shell by a shell hinge. The wallet comprises a sealed side located at the shell hinge, and a clamped top side, right side, and bottom side. The top shell and the bottom shell have a moldable material, which can be a thermoplastic material or other bendable or moldable metal. The wallet can further include a money clip which can be integral with the wallet or a separate piece.

An optical element, notably an optical element for creating a retractable sheet for use in a motor vehicle, has in the final state a three-dimensional shape resulting from forming of the optical element, the optical element being designed to have an extended shape comprising: a first main surface, a second main surface, and an edge surface. A method of manufacturing involves during a first step of the method, forming the optical element to give its final three-dimensional shape in terms of the first main surface, the second main surface and the edge surface. During a second step at least one of the surfaces of the optical element is cleaned. During a third step, a functional coating is applied to the first main surface and/or the second main surface.

A vehicle interior panel includes a decorative skin and a polymer coating provided to increase material thickness at a desired portion of the decorative skin The polymer coating may be formed by a thermal spraying process in which a polymeric material is heated and deposited along an inner side of the decorative skin The decorative skin may be thermoformed from a uniformly thick sheet of thermoplastic material so that it includes a reduced thickness portion after forming. The polymeric material can be deposited along the reduced thickness portion to form the polymer coating, thereby restoring integrity or providing enhanced integrity to the decorative skin to aid subsequent material processes such as sewing or foam backfilling.

The present invention relates to a method for making an aperture web, comprising moving a micro-textured web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.The present invention also relates to a method for making an aperture web, comprising forming microtextures on a web, and continuously moving the web through a first member comprising male elements and a second member comprising discontinuous female elements, wherein the male elements are arranged in a staggered pattern, and have a shape to form quadrilateral apertures in the micro-textured web.
摘要:
A cladding section (100, 200) for mounting upon an elongate member to be deployed underwater is shaped to suppress vortex induced vibration of the elongate member when it is subject to a fluid flow, the cladding section comprising at least one cylindrical or part-cylindrical portion (130, 130′, 130″, 230) to seat upon the elongate member and at least one strake (114,114′, 114″, 214) upstanding from the part-cylindrical portion, the cladding section being characterised in that the strake is resilient, enabling it to be deformed when subject to load and to reform following removal of the load. The cladding section may be prepared by methods involving thermoforming or moulding.
摘要:
An apparatus, such as one or more keyboard keys, comprises at least one form-in-place component that comprises an injection-molded core and a thermoformed film conformally co-molded over at least a portion of the core, wherein the thermoformed film has its smoother side facing outwardly and away from the injection-molded core. Reversing of the film provides a suitable surface for high-resolution character artwork and appearance finish. The smoother surface also allows for top clear coating having a matte, satin or high-gloss finish as desired.

A medical sling for supporting an anatomical feature having ends that are tapered using a folding fixture and then thermoset. The thermoset ends hold the bunched or folded shape thus allowing the ends to be removed from the fixture and placed into a mold assembly where anchors are molded over the ends.
摘要:
A spoke has a rod and at least one tube. The rod is made of a composite material containing thermoplastic resin and fibers. Each one of the at least one tube is mounted on and around the rod and is heated and pressed with the rod to form at least one engaging recess radially embedded in the rod. The spoke engages the at least one tube and the rod via thermoforming the at least one tube and the rod together.
