Composite material for vehicles

Provided is a composite material for vehicles capable of substantially preventing the occurrence of wrinkles caused by ease stitching. This composite material for vehicles is a layered product of a skin material and a polyurethane foam sheet. The skin material has a play structure which, when the composite material for vehicles is stitched, allows the skin material to follow deformation caused by the stitching with a smooth state of a surface of the skin material maintained. The skin material is a woven fabric including warp yarns and weft yarns. The warp yarns and/or the weft yarns include two or more types of yarns having different total finenesses, and form the play structure.

20230123404 · 2023-04-20 · ·

This invention relates generally to flexible materials, especially those made of carbon fiber. The materials exhibit a first flexural modulus over a first range of flexural strain and a second flexural modulus over a second range of flexural strain. The materials provide advantages when used in an article of manufacture in which the performance may be improved by having a different flexural modulus depending on the amount of flexural strain, and thus dislocation, of the material.

Sliding seismic isolation device

A sliding seismic isolation device includes a structure fixation plate having a first sliding surface and a metallic slider having a second sliding surface contacting the first sliding surface. A friction member composed of a single-layer fabric is attached to the first sliding surface, the second sliding surface, or both of the first sliding surface and the second sliding surface. One of a warp and a weft is formed of multiple plied yarns into which high-strength fibers and PTFE fibers are twisted together and the other of the warp and the weft is formed of multiple high-strength fibers in the single-layer fabric. The single-layer fabric has a twill weave and is woven such that the plied yarns of the one forming the single-layer fabric are exposed at a surface opposite from the attachment side of the friction member more than the high-strength fibers of the other forming the single-layer fabric.

Fabric and belt containing it for shear stressing applications

A woven fabric comprising: a) A first layer of first uncrimped weft filaments; b) a second layer of second uncrimped weft filaments; wherein for each of the first uncrimped weft filaments there is one corresponding second uncrimped weft filament, and vice versa, to form successive filament pairs of first and second uncrimped weft filaments, c) crimped warp filaments having four different weave types c1-c4, but each weave type consisting of entwining around first uncrimped weft filaments; passing between first and second uncrimped weft filaments; entwining around second uncrimped weft filaments; and passing again between first and second uncrimped weft filaments; and d) uncrimped warp filaments passing between the first uncrimped weft filaments and the second uncrimped weft filaments of all filament pairs; wherein the fabric does not comprise crimped warp filaments which entwine around the first uncrimped weft filaments and the second uncrimped weft filaments in alternating manner. This fabric has good resistance to shear delamination and wear-and-tear delamination of an impregnation (11) impregnated into the fabric. Accordingly the fabric can be used in belts intended for applications wherein shear stress between the belt's top surface (9) and the belt's bottom surface (10) in the belt's longitudinal direction may occur.
