Abstract:
The present invention is in the field of composite material manufacturing technology, and relates to a prefabricated fabric for liquid molding composite material and a preparation method thereof. The prefabricated fabric comprises a basal fiber fabric, which is characterized in that one or two surface(s) of the basal fiber fabric is(are) conglutinated with a toughening layer. The method for preparing the prefabricated fabric comprises the steps of conglutination of toughening layer, and conglutination of tackifying layer. The prefabricated fabric has both the interlaminar selective toughening and tackifying functions, and realizes the high toughness modification of the composite material while keeping the composite material liquid molding processibility and the good tackifying performance.
Abstract:
A method of making a mat with a textile surface and an elastomer backing is provided. The method includes mixing elastomer crumbs and a binder, depositing the crumb/binder mixture in a layer (22), placing a textile surface element (34) on the layer to form a mat assembly, and pressing the mat assembly in a press (9) while setting the binder. The elastomer crumbs are consolidated to form an elastomer backing (2) that includes voids between the elastomer crumbs, and the textile surface element is bonded to the elastomer backing to form the upper textile layer (1) of the mat.

A component includes a base portion made of fiber-reinforced resin, a first layer formed on the base portion, and a second layer formed on the first layer. A Vickers hardness of the second layer is higher than a Vickers hardness of the first layer. The Vickers hardness of the first layer is in a range equal to or larger than 50 HV and equal to or smaller than 250 HV.
Abstract:
A conductive carbonaceous fiber is provided, comprising a carbonaceous material obtained from carbonizing an electrospun fiber wherein said fiber comprises at least one conductive metal precursor. The electrospun fibers can be formed into fibrous mats during spinning, stabilization and carbonization that are conductive materials which can be used to make stretchable conductors for flexible electronic devices. The invention relates also to the process for making the fibers, corresponding elastomeric fibrous mesh/polymer composites as well as use of these composites for making stretchable electrical conductors. The obtainable elastomeric composite films (with a thickness in the range of 0.8 to 1.5 mm) exhibit good electrical conductivity and excellent electromechanical stability under mechanical deformations (e.g. elongating, twisting and bending). The scalable fabrication process and low-cost precursors make the elastic electrospun carbon fibers/polymer composite conductors promising materials for applications in flexible electronic devices, displays, sensors, wearable conducting clothes, implantable medical devices, etc.

A tufted carpet comprises consecutively a primary backing, stitched with loops of yarn to form a tufted structure projecting outwardly from the primary backing, a polyolefin locking layer, a moisture barrier polyolefin layer, and a secondary backing comprising a woven polyolefin.
Abstract:
A composite elastic layer, which has improved resistance to shear force and functions both as a cushioning material and as a sound proof material, is comprised of a loop pile tufted fabric, which is made from a backing fabric and a plurality of loop piles. An elastomer composition is applied to the pile stratum of the loop pile tufted fabric. The elastomer composition infiltrates into voids between fibers of the loop pile, and forms a solid skin on the fibers of the loop pile. The composite elastic layer reinforces the elastic property of the loop pile, and on the other hand, the fiber of the loop pile also reinforces the tensile strength, especially the resistance to tearing, of the solid skin.
Abstract:
Carpet and textile coating compositions are formulated to include fiber or flock pieces so as to improve the tuft pull strength and dimensional stability of the carpet or textile. The coating compositions comprise 10 to 70%, by weight, of a latex binder and 30 to 90%, by weight, of at least one filler, wherein the filler comprises about 0.001 to 100%, by weight, of fiber or flock pieces. Any natural or synthetic fiber may be used in the coating compositions of this invention.

A carpet composite is provided having improved static electricity characteristics which comprises: a surface layer comprised of face yarn, adhered to a backing layer of thermoplastic resin material into which has been incorporated a mixture of carbon black and carbon fibers in an amount sufficient to improve the static electricity characteristics of said carpet composite.
Abstract:
The pliable building membrane 1 is a non-flammable inorganic fabric 2 defining a first planar side 4 and a second opposite planar side 5. A halocarbon polymer in the form of a fluorocarbon polymer 3 is impregnated into the first planar side 4. The halocarbon polymer may be polytetrafluoroethylene (PTFE), fluorin plastic, ethylene tetrafluoroethylene and/or a tetrafluoroethylene perfluoro propylene co-polymer, for example. Various embodiments have differing ratios of halocarbon polymer to non-flammable fabric and this influences its vapour permeability. A suitable minimum target vapour permeability is approximately 0.15 μg/N·s. An embodiment having a 1:1 ratio has a vapour permeability of approximately 1 μg/N·s, which is well suited for use as a sarking-type material. The non-flammable fabric 2 may be a satin-weave fiberglass fabric or other non-flammable fabrics, such as basalt fibre fabric, or carbon fibre fabric, for example.

A scald-resistant synthetic leather includes a silicone layer and a high-temperature resistant substrate disposed in sequence from top to bottom. A preparing method includes coating and vulcanizating a silicone slurry on the high-temperature resistant substrate, after coating the silicone slurry, sending the high-temperature resistant substrate and the silicone slurry to a drying tunnel for vulcanization to allow attachment of the silicone layer and the high-temperature resistant substrate; after the vulcanization, peeling the silicone layer and the high-temperature resistant substrate apart to obtain the scald-resistant synthetic leather; the number of processes of coating and vulcanizating is more than one, and a thickness for a single coating is 0.02-3 mm; a total thickness for coating is 0.2-0.5 mm. The silicone slurry and the high-temperature resistant substrate used in the disclosure both are environmentally friendly and harmless materials. The high-temperature resistant substrate provides a fundamental framework, and the silicone slurry is the cover.
