Ballistic-resistant articles

摘要

The present invention pertains to a ballistic-resistant article comprising a stack of sheets comprising reinforcing linear tension members, the direction of the linear tension members within the stack being not unidirectionally, wherein some of the linear tension members are linear tension members comprising high molecular weight polyethylene and some of the linear tension members comprise aramid. It is preferred for the polyethylene linear tension members to be tapes. In one embodiment, the stack comprises a layer which comprises more than 50 wt.% of polyethylene linear tension members and a layer which comprises more than 50 wt.% of aramid linear tension members.
