The low velocity impact response of hybrid epoxy composites reinforced with plain weave fabrics, ply orientation at various angles and filled stratified matrix was analyzed in this study. The hybrid epoxy composites were subjected to impact tests at 45J and 90J of energy levels with drop weight impact machine. The damaged areas were investigated by visual inspection of impacted and non-impacted surfaces and by tomographic images. It was found that the replacement of certain carbon inner plies with glass ones and the modification of fiber orientation improved the damage resistance of the hybrid composites with aramid outer layers subjected to impact loading at 45J of energy level.

The introduction of new type of nanomaterials has provided challenges in a deeper level understanding of mechanical behavior and failure mechanisms of fiber-reinforced composites. In this study, a comparison of low-velocity impact behavior of E-Glass epoxy composites modified with 10 wt% nanosilica and 2.5 wt% Nafen™ alumina nanofibers manufactured using vacuum-assisted resin transfer molding is reported. Low-velocity impact tests at three impact energies of 29 J, 39 J, and 50 J are conducted and impact responses, such as impact strength, absorbed energy, and damage area are determined and compared for the two nanoparticles. The damage sustained by composite samples is evaluated by optical microscopy and infrared thermography. Nanosilica-incorporated composites showed rigid behavior, whereas alumina nanofiber-modified composites showed increased stiffness at increased energy of impact as observed from the initial stiffness and deflection of samples. The degree of damage in case of 10 wt% nanosilica-modified composites is reduced by 7.04%, 3.96%, and 7.92% for energy levels of 29 J, 39 J, and 50 J respectively when compared to nonmodified composites, whereas 2.5 wt% alumina nanofiber-modified composites showed 1.66%, −7.35%, and 26.39% for energy levels of 29 J, 39 J, and 50 J, respectively.
