Abstract: A process for producing a fiber reinforced resin which comprises placing at least a reinforcing fiber substrate in a cavity of a mold, injecting a resin into the cavity, and curing the resin, characterized in that a substrate for forming a skin layer, and a resin distribution medium, which is located between the substrate for forming the skin layer and the reinforcing fiber substrate and in which the ratio of the coefficient of impregnation thereof to that of the substrate for forming the skin layer is 1.5-10, are disposed on at least one surface of the reinforcing fiber substrate via an interlayer having a cover factor of 90%-100% and comprising at least one woven fabric. The process diminishes pinhole generation in the skin layer in RTM, and can reduce the necessity of a repair step in, e.g., a painting step as a later step, thereby improving productivity .

Abstract: A sound−proof wall made of FRP in the form of a sound−proof wall panel that comprises a core and skin members made of FRP positioned on both sides of the core and whose weight per unit area is within the range of 10 − 60 kg/m 2 ; and a method of producing the same. This sound−proof wall, though light in weight, has a superior sound insulation property and will never corrode because it is made of FRP. Further, it has a high degree of freedom of engineering design including sound−proof property, design, and shape, capable of producing a desired sound−proof wall with ease. Further, since it has a high specific strength, it is possible to attain a drastic weight reduction while retaining the necessary strength, and to facilitate working, shorten construction time, and reduce construction cost.

Abstract: PROBLEM TO BE SOLVED: To provide a fiber reinforced plastic molded product not imparting dazzlement by reflection even with respect to the incidence of solar rays or the like, and to provide a method for manufacturing the same. SOLUTION: In the fiber reinforced plastic molded product, at least one surface is an uneven surface wherein projected and recessed parts are arranged at random, and formed into a rough surface wherein the average difference between the heights of the projected and recessed parts is not less than 0.5 mm.
