Dec 15 2014 · Aramid composite laminates are reinforced by three kinds of fabric structures and UHMWPE composite laminates are reinforced by two kinds of fabric structures. The laminates are fabricated via autoclave curing process. The ballistic behavior of composite laminates is evaluated by ballistic limit velocity and energy absorbed at ballistic limit. In their own study on the bonding mechanism between aramid fibers and epoxy matrices Kalantar and Drzal 58 showed that epoxy resin shrinkage is not a primary cause of sometimes insufficient adhesion of aramid fibers to epoxy matrices and that the curing temperature does not influence the composite failure mechanism.
