Embodiments described herein relate to a composite structures or sandwiches that may have a relatively high bending stiffness and may have a relatively light weight as well as related methods of use and fabrication of the composite sandwiches. For example, a composite sandwich may include a core structure sandwiched between a two composite skins.

The present disclosure provides a plant fiber textile, a laminate with the plant fiber textile and a fabricating method of the laminate. The plant fiber textile has a matrix resin and continuous plant fibers distributed within the matrix resin. The plant fibers are subjected to a surface modification pretreatment including a coupling treatment with a coupling agent and/or a fire retardation treatment with a fire retardant. The laminate has a stack structure including a layer of the plant fiber textile and at least one layer selected from a group consisting of following layers: glass fiber, aramid fiber or carbon fiber non-woven cloth or textile, preferably distributed within the matrix resin; polymer fiber non-woven cloth or textile, preferably distributed within the matrix resin; or polymer foam or rubber material.

Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.

There is provided an insulation foam in a tubular form, comprising at least one seamless layer of crosslinked polyethylene (PEX) closed-cell physical foam. The tubular foam can favourably be used to thermally insulate tubes that convey water, refrigerants or other fluids, in particular, copper tubes for Heating, Ventilation, Air-Conditioning and Refrigeration (HVAC&R) applications, as well as plastic tubes for use in domestic plumbing systems, hydronic radiant heating and cooling systems. There is also provided a method for manufacturing a crosslinked polyethylene (PEX) closed-cell physical foam in seamless tubular form, an insulation foam material using the same and a polymer blend for its manufacturing.

The disclosure relates to a shape-woven preform which has an omega-shaped cross-section including a core and a sole. At least one part of the core and at least one part of the sole have weft yarns in common with one another.

A ferroelectric polymer electrocaloric nanowire array and a preparation method thereof, in which the ferroelectric polymer electrocaloric material is formed by a polyvinylidene fluoride (PVDF)-based ferroelectric polymer electrocaloric nanowire array embedded in a porous anodic aluminum oxide (AAO) template. The PVDF-based ferroelectric polymer electrocaloric material is controlled to form a nanowire array embedded in the porous AAO template, and through adopting of a solution infiltration method to prepare the ferroelectric polymer electrocaloric nanowire array in the porous AAO template and improvement of the key morphology, structure, internal microscopic connection construction of the ferroelectric polymer, problems, such as low electrocaloric strength of the ferroelectric polymer, difficult heat conduction in the electrocaloric material and low refrigerating power density of the electrocaloric device in the prior art, can be effectively solved.

A method for producing an automotive equipment part includes the following steps: arranging a porous layer in a foaming mold; injection, on one side of the porous layer, of a foam precursor; expansion of the precursor material to form a foam base layer bonded to the porous layer; and extraction from the mold of the equipment part including the porous layer and the foam base layer bonded to the porous layer. The method further includes a step for injecting a pressurized fluid on a second side of the porous layer to form a counter-pressure to the expansion of the precursor material.

A heat-insulating housing (21) includes: a wall body; and an open-cell resin body (4) of thermosetting resin with which a heat-insulating space formed by the wall body is filled by integral foaming, the open-cell resin body including: a plurality of cells (47); a cell film portion (42); a cell skeleton portion (43); a first through-hole (44) formed so as to extend through the cell film portion; and a second through-hole (45) formed so as to extend through the cell skeleton portion, wherein the plurality of cells communicate with one another through the first through-hole and the second through-hole.

The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system. The panel has a lower spring layer based on a resiliently compressible material, an upper mass layer based on resiliently compressible foam flakes, the flakes being bound together by a two-component fibre-based bonding agent comprising a core. The core is fusible at a high temperature or infusible, and a sheath fusible at a lower temperature, the flakes being fused with the sheath to form an upper agglomerated layer.
