Özet: The current study aims to explore the effects of fiber orientation angle on the low velocity impact behaviors of the basalt fiber reinforced composite laminates fabricated by vacuum assisted resin transfer molding. The beam type samples with four different orientation angles (0º/90º, 15º/-75º, 30º/-60º and 45º/-45º) and eight number of layers are tested on the Charpy impact test machine. Furthermore, the failure modes are examined to understand fracture mechanisms on the samples subjected to flatwise and edgewise impact loadings. The results showed that the fiber orientation angle has a substantial influence on the energy absorption and impact toughness of the samples. An increment in fiber orientation angle was resulted with an increase in impact energy and toughness, and also reduction in impact damage. The best values as 3.07 J and 34.82 kJ/m2 for impact energy and impact toughness, respectively, are obtained from the edgewise impacted of notched samples that having (45º/-45º) fiber orientation angle.
