Abstract

Consolidated, layered composites having high penetration resistance to both bullets and fragments are described. The composites comprise, in order, a first non-woven fabric comprising one or a plurality of unidirectionally oriented high tenacity fibrous layers, a felt material comprising high tenacity felt fibers, and a second non-woven fabric comprising one or a plurality of unidirectionally oriented high tenacity fibrous layers. The non-woven fabrics and intermediate felt material are consolidated at facing lateral surfaces.
