Research has shown that the mere folding of PBO fibers, the active component in some soft body armor, can cause a reduction of 15 % to 40 % in ballistic performance. This degradation mechanism in conjunction with hydrolytic degradation of these fibers can result in localized weak spots. This could lead to a catastrophic failure of the armor at a faster rate than occurs when only the hydrolytic degradation mechanism is considered. These results led to a revision of the soft body armor certification protocol.
