PROBLEM TO BE SOLVED: To provide a highly transparent FRP using glass fibers through considering the wavelength dependency of the refractive index of its resin component.;SOLUTION: The FRP is made essentially from glass fibers and a curable resin. This transparent FRP has an overall light transmittance of ≥70%. In this FRP, the cured resin has an Abbe number of ≥45 and such a refractive index that the difference from that of the glass fibers is ≤0.01, the refractive index of the glass fibers is preferably 1.45-1.55, and the glass fibers to be used are in the form of glass cloth, glass paper( nonwoven fabric ), glass mat or the like.;COPYRIGHT: (C)2005,JPO&NCIPI
