Abstract
Provided is a moldable sheet comprising a synthetic organic fiber nonwoven fabric for reinforcing resinous molded article and a resin composition having impregnated the nonwoven fabric. The nonwoven fabric comprises opened single filaments having a specific fineness and bundles of filaments laid parallel with one another having a specific total fineness distribution, said single filaments and said bundles of filaments being bonded with a binder of non-fiber form. By employing this construction, the nonwoven fabric can, when used for reinforcing resinous article, improve the impact resistance, i.e. falling ball impact resistance and Izod impact resistance, which have been poor with conventional glass-fiber reinforced resinous shaped articles, while maintaining the high mechanical strength of the resinous article.
