2066772 9104855 PCTABS00003 A ballistic-resistant article of manufacture which comprises an agglomerated web of two types of discrete fibers. The first type is a fiber formed from polyolefin filament having, in the case of polyethylene filament, a weight average molecular weight of at least about 500,000, a tensile modulus of at least about 300 g/denier and a tenacity of at least about 15 g/denier, and in the case of polypropylene filament, a weight average molecular weight of at least 750,000, a tensile modulus of at least about 160 g/denier and a tenacity of at least about 8 g/denier. The second type is a high density polyolefin fiber having an average fiber length substantially shorter than the first type. The article has a sufficient thickness to absorb the energy of a projectile.
