Structural Member Consisting of Dissimilar Polymer Materials
A structural member including a lightweight core, one or more skins, and a crosslinking nanolayer interposed therebetween that results in significant mechanical strength in the structure. The core is a polymer of reduced density by way of included voids, such as an open or closed cell foam, honeycomb, or corrugated structure. The core polymer has a lower density and may have a higher softening or melting temperature than the polymer skin materials. The core may be discontinuous at the interface with the skin such that only a small percentage of the core surface is actually in contact with the skin compared to the overall area of the interface. The skin may be a thermoplastic layer that attaches to the core material. The skin may be a composite material including non-thermoplastic reinforcements. The crosslinking nanolayer is covalently bonded to the surface of the core material and provides molecular compatibility with the skin material.
Method of anchoring a first object in a second object
A method for joining two objects by anchoring an insert portion provided on a first object in an opening provided on a second object. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. During the step of inserting the insert portion in the opening and/or during anchorage a clamping force is applied to opposing surfaces of the second object to prevent the second object from cracking or bulging.

Break-resistant electric remote control
A remote control for operating an electronic device comprising a plastic housing with a plastic plate segment with a control panel which has at least one control element, preferably button elements and/or at least one directional pad for operating an electronic device,
wherein the plastic plate segment is formed from a plastic material which has an Charpy impact strength of more than 6 kJ/m.sup.2, in particular of 9.0 kJ/m.sup.2+/−0.3 kJ/m.sup.2, wherein the plastic material is an isosorbide-based polymer.
Vehicle outer plate panel and method for manufacturing vehicle outer plate panel
A vehicle outer plate panel includes: a transparent resin plate that is formed into a prescribed shape through pressure molding and is attached to a vehicle so as to constitute an outer wall of a body; and a decorative layer that is formed on at least a part of the transparent resin plate through screen printing such that the transparent resin plate is decorated therewith. A method of producing an vehicle outer plate panel is also disclosed.
Process for joining overlapping thermoplastic membrane components
A method of joining overlapping thermoplastic roofing membrane components in which a first thermoplastic roofing membrane component and a second roofing membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces. Heat is generated in a metal substrate and transferred by thermal conduction from the metal substrate to overlapping portions of the first and second thermoplastic roofing membrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic roofing membrane component and a portion or more of the thermoplastic material of the second thermoplastic roofing membrane component. The molten thermoplastic material of the first and second thermoplastic roofing membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.

Vehicle control panel and production method
A method of producing a control panel for a vehicle. The method includes the following operations: a) producing a touch-sensitive film, the touch-sensitive film including a film, a conductive layer, a main decorative layer, and a secondary decorative layer, the conductive layer being arranged on an inner face of the film, the main decorative layer being arranged on an outer face of the film, and the secondary decorative layer having at least one critical deformation portion arranged on the inner face of the film in at least one corresponding critical deformation zone; b) shaping said touch-sensitive film, the touch-sensitive film being shaped in a non-developable three-dimensional manner in each critical deformation zone; and c) molding a layer of plastic material onto the main decorative layer.
Producing semi-crystalline pulverulent polycarbonate and use thereof in additive manufacturing
Ways of preparing a partially crystalline polycarbonate powder are provided that include dissolving an amorphous polycarbonate in a polar aprotic solvent to form a first solution of solubilized polycarbonate at a first temperature. The first solution is then cooled to a second temperature, the second temperature being lower than the first temperature, where a portion of the solubilized polycarbonate precipitates from the first solution to form a second solution including the partially crystalline polycarbonate powder. Certain partially crystalline polycarbonate powders resulting from such methods are particularly useful in additive manufacturing processes, including powder bed fusion processes.
Thermoplastic resin composition for laser welding, molded article made of same, and composite molded article
Provided is a thermoplastic resin composition suitable for laser welding which has a laser transparency, a good laser weldability, mechanical properties, a high hydrolysis resistance, a laser-welded composite molded article such as a composite article obtained by laser-welding molded resin parts, and a method of laser welding such molded resin articles. The thermoplastic resin composition contains (A) polybutylene terephthalate, (B) polycarbonate, (C) reinforcing fiber, (D) epoxy compound, (E) carbodiimide compound, and (F) phosphorus-based stabilizer.
