Abstract:
1. A method of making an article for use in resisting ballistic threats, comprising: providing a polymer layer comprising a thermoplastic polymer, a thermoset polymer or a polymer having a glass transition temperature of −40° C. to 0° C., a molecular weight of 20,000 to 100,000, and a viscosity of about 2×10 forming a plurality of holes in said polymer layer; and covering and adhering said polymer layer to a first side of a fibrous layer, said fibrous layer having a first and a second side and comprising a plurality of multifilament yarns having a linear density of at least 200 dtex, a tenacity of at least 10 grams per dtex, and an elongation to break of at least 2%; whereby more than 25% and less than 75% of the first side of the fibrous layer is covered and adhered by the polymer layer.
