A method for manufacturing an aeronautical panel with improved impact and damping behaviors. The method is applicable not only to flat panels but also to curved or highly curved panels, whatever their size and the shape of their core. The manufactured sandwich panels comprise dry fiber mats made from fabric material and/or non-crimp fabric material. In a particular embodiment, the fabric material and/or the non-crimp fabric material comprise dry fibers which are recycled and/or reused fibers.

A wavelength conversion member, for a backlight, is provided. The wavelength conversion member includes a stack of a plurality of resin layers, with at least one of the plurality of resin layers containing quantum dots. The plurality of resin layers is integrally molded through co-extrusion, and forms a three-layer structure comprising a middle layer containing the quantum dots and upper and lower layers that do not contain the quantum dots. The upper layer and the lower layer are respectively on an upper side and a lower side of the middle layer. The upper and lower layers each contain a light scattering agent. Each of the plurality of resin layers is directly joined together with a bonding layer at an interface between the middle layer and the upper layer and not at an interface between the middle layer and the lower layer.

A manufacturing method for manufacturing a welded thermoplastic composite and honeycomb core structure is provided. A thermoplastic composite and honeycomb structure is generated by positioning a first thermoplastic composite skin on a support structure, positioning a first thermoplastic film over the first thermoplastic composite skin, positioning a honeycomb core over the first thermoplastic film, positioning a second thermoplastic film is positioned over the honeycomb core, and positioning a second thermoplastic composite skin over the second thermoplastic film. The second thermoplastic composite skin is ultrasonically welded to the honeycomb core. The thermoplastic composite and honeycomb structure is then flipped over, and the first thermoplastic composite skin is then ultrasonically welded to the honeycomb core.

A handle connection mechanism with a handle having a distal end and a proximal end opposite the distal end. The proximal end has a hollow portion. A connector has an outer lateral surface and a recess therein. The recess forms a cavity within the connector. A spring-loaded ball-snap element having a ball and a spring is configured to apply a radial force onto the ball. The spring-loaded ball-snap is positioned within the cavity of the connector. The spring applies a force onto the ball in a direction towards the outer lateral surface of the connector. A head is repeatedly attachable to and detachable from the handle via the connector. A portion of the connector having the spring-loaded ball-snap element therein outwardly extends from the proximal end of the handle and the ball slightly extends beyond the outer lateral surface surrounding the ball.

Articles comprising a skin layer comprising virgin polymer and a core layer comprising a recycled polymer, along with associated systems and methods, are generally provided.

A method for the manufacture of a toy building element with improved functional durability made of an impact modified amorphous material having an enthalpic relaxation of at least 0.3 J/g, such as in the range of 0.3 to 4 J/g and a shrinkage of maximum 0.2%. The present disclosure also relates to a toy building element with improved functional durability made of an impact modified amorphous material having an enthalpic relaxation of at least 0.3 J/g, such as in the range of 0.3 to 4 J/g and a shrinkage of maximum 0.2%.

An object of the present invention is to provide a stretchable polyester having shape followability and flexibility by elastic response and being able to suppress deterioration over time due to secondary crystallization. The present invention provides a stretchable polyester which is an aliphatic copolymer polyester containing two or more types of monomer units, wherein the stretchable polyester contains an -form and an amorphous structure, and a degree of orientation determined by X-ray of the -form is 50% or greater.

The invention concerns a method for producing an optical lens element, in particular for illumination purposes, in particular for producing a headlight lens for a vehicle headlight, in particular for a motor vehicle headlight (10), wherein a pre-lens element (42, 43) is injection molded using at least one mold by heating liquefied transparent plastic, wherein the pre-lens element (42, 43) being cooled in such a way that the plastic solidifies, and at least one optically effective surface of the pre-lens element (42, 43) then being heated in such a way that the plastic on the optically effective surface can be shaped, in particular up to a depth of not more than 1000 micrometers, wherein the pre-lens element (42, 43) is pressed with the optically effective surface in a final contour mold to form the lens element.

Apparatus and methods are described including an additional lens (24) made from an amorphous viscoelastic material and having an optical design. A curvature of the additional lens (24) is changed such as to conform with a curvature of abase eyeglasses lens (22), without causing a loss of the optical design of the additional lens (24), by heating the additional lens (24) to a temperature at which a Tan Delta of the amorphous viscoelastic material is between 0.2 and 0.8, and shaping the additional lens (24). Subsequently, the additional lens (24) is adhered to the base eyeglasses lens (22). The optical design of the additional lens (24) is such that, upon being adhered to the base eyeglasses lens (22), the adhered base eyeglasses lens (22) and the additional lens (24) provide a combined lens (20) having a desired optical prescription. Other applications are also described.

Provided is a method for producing a joined object obtained by joining a columnar base material A, a thermoplastic film B, and a resin C in this order, the method including sequentially performing: a step 1 of winding the thermoplastic film B around at least a part of an outer periphery of the columnar base material A in a peripheral direction; and a step 2 of joining the resin C to a portion of the columnar base material A around which the thermoplastic film B is wound by insert molding to seal the thermoplastic film B.
