Description

ABSTRACT THERMALLY CURABLE WET-IMPREGNATED ROVINGS Thermally curable wet-impregnated rovings are disclosed in which the fibers of the roving are impreg- nated with a liquid polyepoxide having dispersed therein a latent heat-activatable epoxy curing catalyst, such as dicyandiamide, the polyepoxide dispersion having a room temperature viscosity of from 2000 to 5000 centipoises and a tack of less than about 6 on a Thwing-Albert inkometer. The rovings are produced without organic solvent by passing a dry multifilament roving through an elevated temperature bath of the polyepoxide disper- sion, this elevated temperature being insufficient to activate the curing catalyst and functioning to lower the viscosity to enable uniform impregnation. The wet rovings are stored in a supply package.
