Therefore, different parameters like the fiber type, the sedimentation ratio, amount of filling materials and sample thickness have been studied. The effective parameters on material resistance in the ballistic test have been optimized using Taguchi test design method (Minitab15 software). The obtained results show that the best property combination between penetrating impact and impact resistance have been obtained by the layering ratio of 0.6, filling materials weight percentage of 50 % and thickness of 6 mm, respectively, for the composite of Kevlar 49 fibers in epoxy matrix. 收起
