The purpose of the present invention is to provide a sandwich structure that has both excellent heat dissipation properties and excellent mechanical properties. In order to achieve this purpose, the sandwich structure of the present invention has the following structure. The sandwich structure includes a core member (I), and a fiber reinforced member (II) disposed on both sides of the core member (I), wherein the core member (I) includes a sheet-shaped heat conductive member (III) having an in-plane thermal conductivity of 300 W/m.K or more.

An artificial leather includes a resin layer as the surface and a base fabric connected to the resin layer as the substrate. The base fabric comprises at least two monolayer structures arranged in an orderly manner as two laminates. Each monolayer structure is woven with some of the warp yarns and/or weft yarns in such layer or with some of the warp yarns and/or weft yarns in one or more other layers to form a number of connecting points, such that at least two monolayer structures arranged in an orderly manner as two laminates are connected with each other in the weaving process, forming a multi-layer integrated base fabric. The artificial leather incorporates a number of air vent holes distributed in the resin layer and the base fabric in the direction of thickness while retaining mechanical properties of tensile strength and tear resistance.

A method for improving the translation efficiency of fiber strength into composite strength is provided. A single unidirectional tape, single unidirectional fiber web or a stack of unidirectional web/unidirectional tape plies formed from partially oriented fibers/tapes is primed under mild conditions followed by subjecting the primed plies to an axial extension stress in the axial fiber direction of each fiber ply by passage through a compression apparatus. The axial extension stress extends the fibers, strengthening them, while also compacting the plies together and thereby forming a composite having improved strength. Production yield is improved by avoiding maximal fiber stretching and thereby avoiding typical manufacturing loss, and low weight composite armor having increased strength is achieved.

A fabric and a method for making the same. The fabric includes a layer of unidirectionally oriented carbon fibre filaments sandwiched between a first layer of glass fibre rovings and a second layer of glass fibre rovings. The first layer of glass fibre rovings and the second layer of glass fibre rovings are linked by a connecting material.

A honeycomb-like core member that can be easily manufactured is disclosed, and a structure using such core member is disclosed. The core member has a plurality of flat plate members (a plurality of first flat plates and a plurality of second flat plates), each of which includes a comb teeth portion that has a plurality of notches, which are open in the long side of a rectangular shape of the flat plate member and extend parallel to the short side of the rectangular shape of the flat plate member. The notches are engaged with each other so that the plate members cross each other, and thus, a plurality of hexagonal-cylinder-shaped first cylinder portions and a plurality of triangular-cylinder-shaped second cylinder portions are formed by the plate members.

The purpose of the present invention is to provide a heat insulating structure, a heat insulating body, a method for manufacturing a heat insulating structure, and a method for manufacturing a heat insulating body that can substantially reduce a manufacturing cost and a manufacturing time. A heat insulating structure is provided with: a plurality of partition members that are reticulately provided in a space region between one wall part and another wall part opposed to the one wall part and partition the space region into a plurality of partition spaces from the side of the other wall part to the side of the one wall part; and a plurality of fraction members that are provided to support the one wall part and fractionize partition spaces facing the one wall part among the plurality of partition spaces so as to be gradually smaller toward the side of the one wall part.

A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out. In addition, the packing of the settable material and maximum space between the faces are such that only a predetermined amount of liquid can be accommodated within the space and that amount is matched to the water required to set the cement.

There is described a nonwoven material comprising a multilayered stack, the multilayered stack comprising discrete interconnected layers, each of the layers, which may be the same or different, comprising a composite fibre of from about 80 to 100% w/w leaf or stem fibre and from about 1 to 20% w/w of a polymer, wherein the polymer is fusible at a temperature of about 180° C. or less. There is also described a novel method of enzyme degumming leaf and/or stem fibres.

The invention relates to a method of manufacturing a sandwich panel comprises the steps of: a) providing a plate-shaped assembly of a first cover part and a second cover part and between these cover parts a core part of a thermoplastic material containing a physical blowing agent, b) heating the assembly resulting from step a) under pressure between press tools in a press to a foaming temperature below the glass transition temperature of the thermoplastic material in the core part, thereby effecting adhesion of the foamed core part to the first and second cover parts c) foaming the thermoplastic material in the core part under pressure and at the foaming temperature wherein the spacing between the press tools is increased; d) a cooling step of cooling the foamed sandwich panel resulting from step c), while the sandwich panel is maintained under pressure between the press tools; e) removing the thus cooled sandwich panel from the press; and f) drying the sandwich panel thus obtained; wherein the cooling step d) comprises.a first substep d1) of cooling the foamed assembly from the foaming temperature to an intermediate temperature in the range of 70-100° C. at a first cooling rate and a second substep d2) of cooling the foamed assembly from the intermediate temperature to ambient temperature at a second cooling rate, the second cooling rate is less than the first cooling rate.

A floor, wall or ceiling panel comprises a core and a decorative top layer provided on the core. The core comprises a magnesium oxide-based board material, and wherein the aforementioned panel, on at least two opposite edges, is provided with coupling means allowing that two of such panels can be interlocked at the respective edges.
