A core member for a sandwich panel and a method of forming the core member for the sandwich panel which are capable of attaining a desired profile, a desired pattern on their surfaces, and a desired inner structure in accordance with an application of the sandwich panel. There is provided a thermoplastic resin core member interposed between two resin skin sheets comprising a closed hollow portion located to be inside of a desired position in accordance with an application of the sandwiched panel, and it is formed by clamping parison of a molten thermoplastic resin positioned to be between two split molds so as to exhibit a desired profile and/or a surface shape, two surfaces against each of which the molten parison is pressed to form an adhesive surface on which the corresponding resin skin sheet is formed.

A method of manufacturing an article comprises etching an etched feature on a surface of a first polymeric sheet, and forming a fluid-filled bladder element from the first polymeric sheet, with the fluid-filled bladder element having a sealable internal cavity that retains fluid. The method includes assembling the bladder element in the article so that a first portion of the bladder element having the etched feature is exposed to view, and a second portion of the bladder element is blocked from view by the article. An article includes the bladder element with the etched feature.

In various aspects, the present disclosure provides a structural component. The structural component includes a body defining at least one hollow region. The body includes a carbon fiber composite including a plurality of substantially aligned continuous carbon fibers. The plurality of substantially aligned carbon fibers defines a major axis and a second axis perpendicular to the major axis. The plurality of substantially aligned continuous carbon fibers includes a plurality of discrete termination points staggered with respect to the second axis. Methods of making such structural components, including by blow molding and compression molding are also provided.

A process is disclosed for manufacturing at least one wall of a tank and comprises at least a first layer of thermoplastic and a second foam-based layer. The second foam-based layer forms at least part of an anti-slosh device, and the process is characterized in that the first layer and the second layer are molded in the same mold.

A beverage container lid includes an interior cover, an exterior cover, and a hinge connecting the interior cover to the exterior cover. The beverage container is versatile in that it may be adapted for use with a beverage container containing a cold beverage, a hot beverage, or a foamy or creamy beverage. The beverage container lid preferably includes a spout, straw perforations, an elevated portion, a reservoir bottom, a well portion, and a pair of retaining walls preventing direct flow of beverage from a pair of openings in the interior cover to the spout. Methods of use and methods of making a beverage container lid are also described.

A heat-insulating transparent PVC sheet is formed from a PVC substrate having a thickness of 0.02-2.0 mm and contains heat-insulation pastes evenly distributed over the PVC substrate, since the heat-insulation paste contains an essential component of wolfram cesium powder (WCs) with a chemical formula of Cs.sub.XN.sub.YWO.sub.3-ZCl.sub.C and having a particle size of 0.005-2 m, the heat-insulating transparent PVC sheet has an excellent weatherability, and particularly before and after tested in 300-hour service life in line with ASTM G-154 specification, has a physical property of weatherability decay rate (%) small than 4%.

The disclosure relates to oxygen scavenging polymer compositions, methods of making the compositions, articles prepared from the compositions, and methods of making the articles. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The use of sheets comprising at least one face consisting of a pseudo-amorphous composition based on polyaryl ether ketone(s) for a twin sheet thermoforming process. A twin sheet thermoforming process for manufacturing a hollow body. A hollow body comprising at least one internal surface consisting of a crystallized composition based on polyaryl ether ketone(s), obtainable by the process.

The invention concerns a process for the production of a container, in particular a fuel tank of thermoplastic material, by extrusion blow molding, wherein during shaping of the container within a multi-part tool the container is provided with at least one connecting element passing through the wall thereof, wherein with at least a part of the connecting element as a lost shaping male die the wall of the container is displaced from one side into a tool placed on the oppositely side of the container wall and removed. The invention further concerns a fuel tank with at least one connecting element which is connected to the tank wall at least in region-wise manner by intimate joining of the materials involved.

A method for manufacturing a plastic fuel tank including: a) inserting a plastic parison including two distinct parts into an open two-cavity mold; b) inserting a core, bearing at least part of a reinforcing element configured to create a link between the two parison parts, inside the parison; c) pressing the parison firmly against the mold cavities, for example by blowing through the core and/or creating suction behind the cavities; d) fixing the part of the reinforcing element to at least one of the parison parts using the core; e) withdrawing the core; f) closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; g) injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; and h) opening the mold and extracting the tank.
