Samples with four different orientation angles (0º/90º, 15º/-75º, 30º/-60º and 45º/- </span> <span style="font-size:12px;">45º) fabricated by vacuum assisted resin transfer molding have being tested on the Charpy impact test machine. Furthermore, </span> <span style="font-size:12px;">failure modes of notched/unnotched samples subjected to impact loadings in the flatwise and edgewise directions have </span> <span style="font-size:12px;">been examined to detailly understand fracture behavior. The results showed that the fiber orientation angle has substantial </span> <span style="font-size:12px;">effects on the energy absorption capability and impact toughness of the samples. The increment in fiber orientation angle </span> <span style="font-size:12px;">was led to increases in impact energy and toughness, and the reduction in impact damage. The best values as 3.07 J and </span> <span style="font-size:12px;">34.82 kJ/m <sup>2 </sup> </span> <span style="font-size:12px;">for impact energy and impact toughness, respectively, are obtained from the notched samples in edgewise </span> <span style="font-size:12px;">impact loading that having (45º/-45º) fiber orientation angle. Almost all of the samples exhibited failure modes as matrix </span> <span style="font-size:12px;">fragmentation, delamination, fiber cracking and fiber pull-out, respectively. The most destructive results were observed as </span> <span style="font-size:12px;">laminate fracture on the samples having (0º/90º) fiber orientation angle. </span> </div>}, number={4}, publisher={Murat YAKAR}
