• Discs of uniform thickness with a hole at the center were molded by winding the prepregs of glass fiber roving with polyester resin. A circumferential crack occurred in the disc when the inner to outer radius ratio of the disc became larger than a certain critical value. It was found that this crack was due to residual stresses in the disc developed in molding process. The distribution of residual stresses in the discs were analysed by considering anisotropic shrinkage of impregnated roving during the setting and cooling processes. These theoretical results approximately coincided with experimental results. From these results, it was made possible to predict the critical value of the inner to outer radius ratio less than which the crack did not occur in molded discs. It was also shown that the autofrettaged discs with arbitrary inner to outer radius ratio could be molded by anisotropic shrinkage of resin impregnated roving.
