Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives __Scope & General and T, this invention is more specific about the coated fiber used to reinforce the composite & it is about the coated particles Glass fiber strands, the particles providing interstitial spaces between adjacent glass fiber strands. In thermal molding, good "wet-through" (polymer matrix material penetrates through the mat or fabric) and "wet," (polymer matrix material penetrates through individual fiber bundles or strands in the mat or fabric) The nature is generally desired. By contrast, good dispersion properties are a major concern in typical thermoplastic molding operations. Japanese Patent Application No. 9-208,268 discloses a cloth having yarns made of glass fiber, which is coated with starch or synthetic resin immediately after spinning, and inorganic solid particles of 0.001 to 20.0 weight percent, For example, colloidal silica, calcium carbonate, kaolin, and talc have an average particle size of 5 to 2000 nanometers (0.05 to 2 micrometers) to improve resin impregnation. In paragraph 13 of its detailed description, it is disclosed that such a coating having more than 20% by weight of inorganic solid particles cannot be applied to glass fibers. Before forming the laminate, heat or water degreasing is required to remove the coating from the glass fibers. U.S. Patent 3,312,569 discloses adhering alumina particles to the surface of broken glass fibers to improve the penetration of resin between glass-reinforced fibers during composite formation. However, the Mohs hardness of alumina is more than about 9m, which may cause wear of softer glass fibers. 1. See R. Weast (ed.), Handbook of Chemistry and Physics.

Printed by the Soviet Union Federal Patent 859400 by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics discloses an impregnated composition for manufacturing glass fiber cloth laminates, which composition contains an alcoholic solution of phenol-formaldehyde resin graphite, molybdenum disulfide, polyethylene埽 Butyral and surfactant. Volatile alcoholic solvents are not desirable for glass fiber manufacturing applications. The hollow% particles can be used to modify the impregnation properties of the reinforcing material and / or reduce the overall density of the composite material made from it. For example, U.S. Patent No. 5,412,003 discloses impregnating glass fibers with a resin composition containing an unsaturated polyester, a polymerizable monomer, a thermoplastic resin, a polymerization initiator, and hollow glass microspheres (line 2, lines 6-14). The molding materials and molding products obtained from this impregnated fiber are lightweight (block 2, line 26_30). U.S. Patent No. 4,820,575 discloses that hollow bulk fillers, and particularly thermally expandable neutral bulk fillers, have a particle diameter ranging from about 20 to about 300 microns and are incorporated into the gap between the core fibers of the reinforcing material to permanently Reduce the resin adhesion and specific gravity of the reinforcing material (block 4, line 39_43, and block 3, line 15_30) This filler is preferably applied to the reinforcing material with a suspension containing no water and no adhesive ( Column 3, lines 63_68, and block 4, line 3). U.S. Patent 5,866,253 discloses the incorporation of thermally expandable hollow particles into a fiber strand. The particles can expand into " microballoons " to produce fiber strands with enlarged cross-sectional dimensions for use in composite materials. Expanded particles usually have particle sizes ranging from about 40 to 50 microns, which are larger than the diameter of the strand fibers (line 3, lines 5-10). When compared to fibers that do not use expanded particles, fiber strands with expanded particles typically have a diameter that increases by about four times, and the density of the strands is considerably reduced (line 4, line 12-18). The larger strand diameter allows less strands to be used in the formation of the composite, so a lower ___ _ _5_ is provided for this paper size.

Many glue components commonly used on fiber strands to be woven into fabrics may be unfavorable. ≫ To glass fiber and laminate matrix Adhesion between materials. For example, starch, which is a commonly used glue component of textile fibers, is generally not compatible with laminated resin matrix materials. To avoid incompatibilities between glass fibers and matrix materials, this coating or The sizing composition is typically removed from the woven cloth before lamination by thermally decomposing the glue ingredients (called thermal cleaning or degreasing) or washing the cloth with water. The conventional thermal cleaning method for thermal decomposition of pulp components involves heating the cloth at 380 ° C for 60-80 hours. Then, the hot-cleaned cloth is recoated with a silane coupling agent to improve the gap between the glass fiber strand and the matrix material. However, this deoiling method may not always be completely successful in removing incompatible materials, and may further contaminate the fabric with the products of decomposition.
