Abstract
Rovings impregnated with solid or preferably semi solid thermosetting resin and which can be handled in textile processing equipment are provided by overcoating the impregnated roving with a thermoplastic resin dispersed in a volatile liquid medium which does not dissolve the thermosetting resin to form an encapsulating membrane of thermoplastic resin around the impregnated roving to thereby provide the strength, flexibility, and surface properties needed for textile handling without degrading the properties desired in the final cured molded product.
