Beschreibung
Zusammenfassung:	A process for forming flat plate ballistic resistant composites which includes impregnating a low-alkali magnesia-aluminum-silicate glass fiber woven roving with an impregnating composition. The impregnating composition includes a resin solution of a polyester resin in a polymerizable monomeric solvent a free radical catalyst and optionally, a thickening agent and further optionally a flame retardant material. The impregnated woven roving is cured in a molding unit at a temperature of about 225 DEG -255 DEG F. for a sufficient period of time and at a sufficient pressure to allow the impregnated woven roving to substantially conform to the mold unit. The temperature and pressure used are sufficient to maintain the exothermic temperature at about 300 DEG F. or below and to catalytically crosslink the polyester resin and monomeric solvent.
