Ballistic-resistant articles comprise a plurality of polybenzoxazole or polybenzothiazole polymer fibers and are lighter, more comfortable to wear and exhibit better ballistic-resistant properties than existing ballistic-resistant articles of equal weight.

Ballistic-resistant article and process for making the same

A flexible, uncoated glove made from nonmetallic fabric comprising at least one fiber is disclosed. The glove is characterized by either weighing no more than about 30 g or having a thickness of no more than about 1.25 mm (0.05 inch), being cut resistant over some portion thereof by enduring without cutting through at least 5 cycles of an impact cam cut test, having compliance so that the wearer has a high degree of tactility, and having a cut resistance of at least 5 cycles of an impact cam cut test after a disinfectant treatment with sodium hypochlorite. The gloves are particularly useful in the medical field where they provide excellent cut protection and can be disinfected at least once while maintaining an acceptable level of cut resistance. In an alternate embodiment, a similarly characterized glove is made from a layer of fibrous material adhered to a surface of an elastomeric glove without being fully encapsulated thereby. This glove is also particularly useful in the medical field where it provides excellent cut protection.

A dry clutch is prepared from a composite of fiber yarns, including fiberglass fibers and polymer fibers such as polyacrylonitrile fibers, which are blended together and twisted with wire. The yarns are shaped in a disc or other form and are bonded together with a heat curable binder system that includes an elastomer and a resin. The binder system also may contain organic and inorganic friction modifying particles.
