A panel comprises a non-deformable first woven fabric and a non-deformable second woven fabric, and a linking structure comprising stays linking the first woven fabric to the second woven fabric, each stay having an at-rest length that is substantially equal to the mean of the at-rest lengths of the stays, the panel comprising a cement-based foam.

A layered thermal insulation system generally conformable to three-dimensioned surfaces of heat-producing elements in need of insulation is described. The system comprises: i) an inner high temperature resistant insulation layer; ii) an outer high temperature resistant insulation layer adjacent the inner high temperature resistant insulation layer; and, iii) a first reflection layer and a second reflection layer. Each of said reflection layers is formed of a material selected from a group consisting of metal foils and are provided with a plurality of dimples and/or protrusions. The first reflection layer is adjacent the inner high temperature insulation layer such that, in use, an opposing surface thereof is in close proximity to said surfaces of said element to be insulated. The second reflection layer is adjacent to the outer high temperature insulation layer such that, in use, an opposing surface thereof comprises an exposed surface having a lower temperature than said surfaces of said element.

In order to reduce adhesive residue of an adhesive tape, an adhesive tape is provided, including a base material 10 having a base fabric 1 composed of warps and wefts, a first laminate layer 2 formed on a first surface 1A of the base fabric, and a second laminate layer 3 formed on a second surface 1B of the base fabric; and an adhesive layer 6 formed as an outermost layer on the side of the base material 10 on which the first laminate layer 2 is formed, wherein an unevenness 2B formed due to the warps and the wefts is formed on a surface of the first laminate layer opposite to the base fabric.

A woven EMI sleeve has a wall with opposite edges extending lengthwise between opposite ends. The wall is wrapped about a central longitudinal axis into a tubular configuration bounding an enclosed cavity sized for receipt of an elongate member therein. The wall is woven with warp filaments extending generally parallel to the central longitudinal axis and weft filaments extending generally transversely to the warp filaments. The warp filaments include conductive filaments provided as wire filaments and separate non-conductive warp filaments. The weft filaments include heat-set filaments that are heat-formed to bias the wall into the tubular configuration and to bias opposite edges into overlapping relation with one another. The weft filaments also include conductive filaments.

The disclosure relates to a toothed belt including: a back portion in which a tension member is embedded; a plurality of tooth portions formed on an inner circumferential surface of the back portion; a back rubber layer formed on a belt outer circumference side with respect to the tension member; and a first rubber layer and a second rubber layer formed on a belt inner circumferential side with respect to the tension member, in which an inner circumferential belt surface is formed of a tooth fabric, the back portion includes the back rubber layer, an elastic modulus of the first rubber layer is larger than an elastic modulus of the second rubber layer, and the tooth portion includes the tooth fabric, the first rubber layer formed along the tooth fabric, and the second rubber layer interposed between the first rubber layer and the tension member.

A commingled fiber preform is provided. The commingled fiber preform includes at least one first fabric layer and a second fabric layer. The second fabric layer is positioned on top of the at least one first fabric layer. The second fabric layer is joined to the at least one first fabric layer via through thickness reinforcement (TTR) using a commingled thread. A transport depth of the TTR penetrates completely through a thickness of the second fabric layer and an entirety of the at least one first fabric layer. The commingled thread comprises carbon fibers commingled with fugitive fibers. The fugitive fibers are pyrolyzed from the commingled fiber preform to create a path through the thickness for infiltration of fluids.

Multilayer structure for transporting hydrogen, including, from the inside, at least one sealing layer and at least one composite reinforcing layer, an innermost composite reinforcing layer being wound around an outermost adjacent sealing layer, the sealing layers of a composition predominantly of at least one semi-crystalline, long-chain polyamide thermoplastic polymer P1i (i=1 to n, n being the number of sealing layers), the Tf of which, as measured according to ISO 11357-3: 2013, is greater than 160 C., with the exception of one polyether block amide (PEBA), up to 50% by weight of impact modifier relative to the total weight of the composition and up to 1.5% by weight of plasticiser relative to the total weight of the composition, the composition being free of nucleating agent, and at least one of the composite reinforcing layers being of a fibrous material.

A multi-piece floor arrangement and assembly forms a floor covering that includes a top, or upper, rug portion and bottom, or lower, mat portion, and pocketed corner areas in each corner of an underside surface of the rug portion into which corresponding corners of the mat portion are insertable. The pocketed corner areas secure the rug portion with the mat portion when both are placed on an underlying surface while enabling a flow of air between the rug portion and the mat portion. The mat portion includes multiple interlocking sections that help to maintain the floor covering in a uniform planar shape and provide an aesthetically-pleasing appearance when placed on an underlying surface. The multi-piece arrangement and assembly does not move relative to that surface, yet does not require either a cumbersome installation or removal process.
