A resin panel according to an embodiment includes a core material, a reinforcing material, a skin material covering the core material and the reinforcing material, and a fastened member. A reinforcing material has a first plate provided on a front surface of the core material, a second plate provided on a back surface of the core material, and a connecting plate connecting the first plate and the second plate. The fastened member is attached to the skin material by a fastening member penetrating the skin material and the first plate or the second plate of the reinforcing material.

The combination of 3D printing technology plus the additional dimension of transformation over time of the printed object is referred to herein as 4D printing technology. Particular arrangements of the additive manufacturing material(s) used in the 3D printing process can create a printed 3D object that transforms over time from a first, printed shape to a second, predetermined shape.

A method of forming a composite structure including coupling a plurality of components together forming a joint: wherein the plurality of components are oriented to form a radius gap therebetween: forming a filler structure that includes a closed cell foam core that has a porosity within a range defined between about 20 percent and about 40 percent by volume of the closed cell foam core and wherein the closed cell foam core is formed from a silicone-based material. The method also includes positioning the filler structure in the radius gap: and applying at least one of heat or pressure to the plurality of components and the filler structure.

A method of molding a collapsible, foam plastic container; the method employs two half-molds defining a molding chamber negatively reproducing the container in an erect work configuration, and forms a hinge for each lateral wall of the container when molding the container; each hinge being formed by a parting member which is inserted through the molding chamber at the hinge to be formed, and by a compression member opposite the parting member and which is moved towards the parting member to form, on the lateral wall, a small-section, higher-density portion defining the respective hinge.

A portable information handling system presents visual images with a flexible display disposed over separate housing portions rotationally coupled by a set of hinges having an opening defined between them. A multi-segmented support couples to the hinges in the opening to dispose a planar surface proximate the flexible display and extend plural parallel members up from the planar support between the hinges, the plural parallel members separating in response to rotation from a flat to a curved orientation.

A composite structure with an integrated hinge is disclosed. In various embodiments, the composite structure includes a plurality of layers of fiber reinforced polymer material; and a hinge structure comprising one or more layers of bendably flexible hinge material a first region of which is interleaved between adjacent layers of said layers of fiber reinforced polymer material comprising the composite structure and bonded to said adjacent layers by bonding material comprising said composite structure, and a second region of which extends beyond said layers of fiber reinforced polymer material comprising the composite structure.

The present disclosure provides a plastic living hinge. The plastic living hinge includes a blend containing (A) an ethylene-based polymer; (B) a propylene-based polymer; and (C) a composite component selected from the group consisting of a block composite, a crystalline block composite, and a combination thereof.

There is disclosed a mould for forming a collapsible container from an expandable material, the container comprising, when assembled, at least a base and a two pairs of a side walls extending at right angles from opposing sides of the base, the mould comprising: a first mould member and a second mould member movable with respect to each other between an open and a closed moulding position to define a mould cavity; a control means for delivering expandable material into said mould cavity and for delivering steam to facilitate expansion of the expandable material within said mould cavity to form said container; and a plurality of anvils mounted on a rear surface of at least one of the first mould member and/or second mould member, each anvil being movable so as to be extended into the mould cavity so as to form one or more hinges in the expandable material at predetermined locations within the mould cavity; wherein the mould cavity defined by the first mould member and the second mould member is a three-dimensional representation of an inside-out configuration of the assembled container.

A hinged component includes first and second portions of material coupled together by a composite live hinge. The live hinge includes a layer of tensile fabric and a layer of elastomer interposed between the tensile fabric and the material of one or both of the coupled first and second portions. The composite live hinge is capable of joining structural composite materials without the need for scoring, and thereby weakening, the structural composite material along the desired hinge line. The live hinge can be embedded in the materials it joins in a method that is compatible with traditional structural composite layup processes and in a manner which prevents resin from the structural composite materials from infiltrating the tensile fabric and compromising its flexibility.
