| 20130123406 | FORMALDEHYDE FREE BINDER COMPOSITIONS FOR FIBROUS MATERIALS - Compositions for binding organic or inorganic fibers is described. The compositions may include an aqueous solution having a pH of about 4.5 or more. The aqueous solution may include a polycarboxy polymer that is about 10%, by wt., to 100%, by wt., of a butenedioic acid or butenedioic anhydride; and a polyol. The compositions can maintain a pH of about 5 or more after being cured into a thermoset plastic with the fibers. Processes for preparing a binder composition for organic or inorganic fibers are also described. The processes may include providing an aqueous solution of polycarboxylic acid polymers, where the polymers comprise about 10%, by wt., to 100%, by wt., of a butenedioic acid or butenedioic anhydride; adding a polyol to the aqueous solution; and maintaining the pH of the aqueous solution at about 5 or more. | 05-16-2013 |
| 20130040108 | MODIFIED FIBERS FOR USE IN THE FORMATION OF THERMOPLASTIC FIBER-REINFORCED COMPOSITE ARTICLES AND PROCESS - A surface-modified fibrous material is provided for incorporation in a thermoplastic matrix to form a fiber-reinforced composite article. Good binding between the fibrous material and the thermoplastic matrix is achieved through the presence of finely roughened surfaces on the fibers of nanoparticles of an inorganic material. Such nanoparticles are provided from an alkaline aqueous size composition containing the nanoparticles dispersed therein (as described). The fibrous material may be provided in continuous or discontinuous form. In a preferred embodiment glass fibers are initially provided in continuous form followed by cutting into discontinuous lengths and drying with the retention of the nanoparticles on the surfaces of the fibers. The surface-roughened fibrous material is incorporated in a thermoplastic matrix as fibrous reinforcement with the application of heat whereby the thermoplastic matrix is rendered melt processable. In preferred embodiments injection or compression molding is utilized. Improved long-fiber thermoplastics also may be formed to advantage. | 02-14-2013 |
| 20100305269 | METHODS AND SYSTEMS FOR MAKING REINFORCED THERMOPLASTIC COMPOSITES, AND THE PRODUCTS - Various methods and systems of making inorganic fiber/flake reinforced composites having a thermoplastic matrix are disclosed. The methods use systems similar to those used to make inorganic fiber/flake reinforced products having a thermoset matrix, but the systems and methods are modified to use thermoplastic precursor monomer(s) followed by in situ polymerization of the monomer(s) during and/or following forming of the desired shape of the products. These methods permit the manufacture of superior inorganic fiber reinforced thermoplastic matrix composites in large and very large shapes heretofore not possible, or practical. | 12-02-2010 |
| 20100291827 | BASE INTERLINING AND COATED ROOFING MEMBRANES - The invention relates to a new base interlining for producing roofing membranes which have to meet a wide variety of requirements. The new base interlining provides a sufficient mechanical stability, good perforation strength, good tensile strength and a high resistance to thermal stress, inter alia required for base interlining during bituminization. In addition, the new base interlining requires a considerable reduced volume of impregnating bitumen when producing bituminized roofing materials and therefore high costs of special bitumens for filling the base interlining can be avoided. Beside the new base interlining, a method for producing it as well as roofing membranes comprising the base interlining are subject matter of this invention. | 11-18-2010 |
| 20100221973 | COMPOSITE MATERIALS, METHOD FOR THEIR MANUFACTURE AND THEIR USE - The invention relates to the manufacture of new composite materials suitable in particular as materials in interior construction, for linings, constructions and for the manufacture of furniture and similar products. | 09-02-2010 |
| 20100167005 | DIRECTLY DECORATABLE COMPOSITE MATERIALS, METHOD FOR THEIR MANUFACTURE AND THEIR USE - The invention relates to directly decoratable and/or printable composite materials suitable in particular as materials in interior finishing, for linings, constructions and for the manufacture of furniture and similar products. | 07-01-2010 |
