In this study, impact behavior of a polyester resin reinforced with chemically etched and unetched Kevlar 49 fibers was presented. The effect of chemical etching on the strength of single fibers was investigated. Since the fiber/matrix interfacial strength plays a critical role in the mechanical performances of fiber reinforced composites, the bonding behavior of Kevlara 49 fibers to polyester resin has been conducted. Also, the effect of fiber length and fiber volume fraction on the ballistic performance of these composites were investigated by studying their behavior under impact shock loading. The failure mechanism of the system was examined and discussed.
