摘要:
The present invention relates to a non-woven fabric made of inorganic fibers, which has a coating of at least two layers on one of both surfaces, wherein (i) the non-woven fabric made of inorganic fibers has a thickness of at least 0.2 mm, (ii) the first layer of the coating comprises particles, whose particle size is between 50 and 100 μm, (iii) the second layer of the coating, which is applied onto the first layer, comprises particles, wherein more than 90% of the particles have a particle size of less than 20 μm. The non-woven fabric made of inorganic fibers according to the invention, in particular glass non-woven fabrics, are in particular suitable for producing decorative coatings for floor coverings, ceiling coverings and wall coverings.

An athletic tape or protective athletic sleeve is formed from an impregnated fabric substrate that is sealed on both sides. The impregnated fabric includes a shear thickening fluid that is made up of a suspension solution and solid particles. The shear thickening fluid is sealed within the fabric through use of sealing layers on both sides of the fabric.

A method of preparing a composite configured to release refrigerant therefrom comprises providing a substrate material comprising polarized fibers of glass, polyamide, phenylene sulfide, carbon or graphite bonding thereon a metal compound comprising a complex compound of a polar gaseous refrigerant and a metal salt and/or a hydrated metal hydroxide and/or a metal hydroxide of a metal comprising alkali metal, alkaline earth metal, transition metal, zinc, cadmium, tin, aluminum, or two or more thereof, at a concentration of at least about 0.3 grams/cc of open substrate material volume, forming layers of the metal compound bonded substrate material, and sealing at least one layer or the exterior surface of the substrate material with a coating composition configured to prevent release of internal gaseous refrigerant therethrough at ambient temperatures and pressure and capable of penetration of gaseous refrigerant therethrough from the composite interior at temperatures causing internal gas pressures of 15% or more above exterior pressure for such refrigerant release.
摘要:
The present invention relates to a urethane-based coating having nanoparticles for improving the characteristics of a papermaking process belt, roll cover and belts used in textile applications. For example, the present invention improves resistance to flex fatigue, crack propagation, groove closure and wear characteristics of urethane coatings on such belts and roll coverings. The present invention also improves the resistance to water and oil permeation characteristics of urethane coated belts and roll coverings.

A protection product has thermal and acoustic barrier characteristics such that it satisfies the requirements of the standard 14 CFR, part 25 issued by the Federal Aviation Administration. The product is designed to be applied along metallic and composite structures, such as aircraft cockpits, boat hulls or the outside structures of trains or of other means of transport. The product is essentially in the form of a “mat” consisting of one or several fiber layers, preferably glass fibers, enclosed in a sheath. The sheath generally comprises at least one first support, preferably made of an organic material having sealing and anti-condensation properties, and an impregnated mica paper. The mica paper preferably has a weight per unit area of less than 50 g/m2 and comprises flakes of mica with a form factor greater than 1000.

摘要:
The present invention relates to a composite article and to a process for manufacturing the composite article. The composite article comprises multiple layers including high tenacity fibers incorporated into a fabric and a core thermoplastic resin. The fabric may be coated with a surface treatment agent, a polymer matrix resin. Single or multiple layers of the composite articles may be formed into a composite part having high strength, rigidity, fast molding cycle time and extremely good conformability in a 3-dimensional mold. The composite parts formed by this process have high part strength in all directions.
