<p>The invention relates to a ballistic resistant material having a V50 value of at least about 1000 feet per second. The ballistic resistant material includes at least two types of fibrous materials, which are blended and consolidated together, preferably by needlepunching, to create a single layer of nonwoven, composite material. The needle punching is preferably in the range of 200 to 1000 needlepunches per square inch. The fibrous materials are characterized by being deformed when subjected to the impact of a ballistic object. One of the fibers phase changes, e.g. melting, upon impact and at least one other fiber fibrillates upon impact. One of the fibers must phase change at a temperature at least 80 °C lower than the highest melting or destruction point fiber in the high modulus fiber blend.</p> |
