Zusammenfassung:	Method for making a laminated ballistic helmet from plural, continuous filament resin-coated layers. A continuous filament bundle, yarn or end is deposited on a plurality of different sized helmet-shaped preforms. A resin is coated upon or impregnated into the continuous filament bundle, yarn or end, either before or after deposition. The resulting resin containing preforms are stacked in nested relation and then molded to produce a bonded, laminated ballistic helmet.
