Abstract
Rovings impregnated with a semi solid mixture of thermosetting resin and thermoplastic resin and which can be handled in textile processing equipment are provided by overcoating the impregnated roving with a thermoplastic encapsulating resin to form an encapsulating membrane of thermoplastic resin around the impregnated roving which provides the strength, flexibility, and surface properties needed for textile handling. The thermosetting resin is preferably an epoxy-resin dicyan-diamide combination and it is preferably used in admixture with a polysulfone resin.
