Abstract
A process is provided for manufacturing ballistic resistant composites of an isophthalic thermoset polyester and woven roving made of magnesia aluminosilicate glass fibers. An impregnating solution is provided whereby prepregs can be conveniently formed and then vacuum bag molded. The ingredients i the impregnating solution are critically selected to provide prescribed viscosities after the elapse of certain periods of time and thereby allow the final articles to be formed in an economical and expedient manner.
