BALLISTIC RESISTANT ARTICLES COMPRISING TAPES

摘要

A ballistic-resistant molded article includes a compressed stack of sheets made up of reinforcing tapes having a tensile strength of at least 1.0 GPa, a tensile modulus of at least 40 GPa, and a tensile energy-to-break of at least 15 J/g, the direction of the tapes within the compressed stack being not unidirectional. The stack includes a first layer of sheets including reinforcing tapes and a high-density polyethylene (HDPE) as matrix material and a further layer of sheets including reinforcing tapes and a thermoplastic elastomer as matrix material, wherein the further layer includes 0.2-8 wt. % matrix material.
