| Abstract | A helmet shell formed from two types of high tenacity fibers in multiple layers of fibrous materials. The fibrous materials are in the form of layers of fibrous networks in a resin matrix. There are a plurality of each type of fibrous layers. Preferably the outer set of fibrous layers is formed from aramid fibers and the inner set of fibrous layers is formed from high tenacity polyolefin fibers. There may also be employed a third type of fibrous material as an additional set of fibers and used as the outer layers of the helmet shell. The third type of fibrous layers is formed from glass fibers that are also in a resin matrix. The helmet is lightweight, has excellent ballistic resistant properties and is useful for both military and non-military applications. |
