Abstract
This invention is directed to a flexible penetration resistant stabilized composite, that includes an interlaced yarn structure of yarns having a tenacity of at least 8 g/d, a tensile modulus of at least 150 g/d and an energy to break of at least 10 j/g. The yarn structure includes yarn subgroups alternately stacked together. There is also provided a polymeric web coextensive with, in contact with, and bound to the surface of one of the subgroups that at least partially contacts and is bound to the yarns in all the subgroups in the stack to thereby contain the subgroups in the stack in an interlaced yarn structure.
