Abstract:
Fiber-reinforced polymer (FRP) composites are widely used in aerospace, automotive, and marine industries due to their superior strength-to-weight ratio, corrosion resistance, and design flexibility. Among the various manufacturing techniques, the Vacuum-Assisted Resin Transfer Molding (VARTM) method provides an efficient and cost-effective means to fabricate large, high-quality composite structures with good fiber wet-out and low void content. This study investigates the low-velocity impact behavior of E-glass fiber/epoxy composites fabricated by VARTM at two fiber orientations ([0]?? and [45]??). The composites were subjected to drop-weight impact tests at 5, 10, and 20 J according to ASTM D7136/D7136M standards. The results showed that the [0]?? orientation exhibited higher impact resistance, load-bearing capacity, and reduced delamination compared to the [45]?? specimens. The study provides insights into the relationship between fiber orientation and impact response, emphasizing the significance of processing parameters and fiber alignment in structural applications.
