Abstract

A helmet shell is formed having an outer section of fibrous layers, a middle section of fibrous layers and an inner section of fibrous layers. The outer section layers contain high tenacity abrasive fibers in a resin matrix. The middle section layers contain high strength polyolefin fibers and are in the form of woven or knitted fabrics with a resin matrix. The inner section layers contain high strength polyolefin fibers and are in the form of non-woven fabrics with a resin matrix. The helmet is lightweight and resists penetration of rifle bullets.
