ABSTRACT:
A multi-layer armor comprises: an outer composite spaced from an inner composite. The outer composite comprises (a.) a high strength strike surface layer, (b.) a high strain rate sensitivity-hardening polymer and (c.) a second high strength layer. The inner composite comprises spaced silica glass layers, an acrylic glass layer and a spall liner. In one embodiment the armor is transparent and used to shield a vehicle windshield. In a second embodiment the armor is opaque and is attached to vehicle base armor. The armor may also be applied to a ship. The armor uses commercially available components, is relative inexpensive and is effective.
