The expanding demand for sustainable, environmentally safe, weightless, and robust materials and aviation sector designs inspired this study. Evaluation of damage-related capabilities and rates of failure of hybrid composite laminates during impact tests at low velocity is presented in this work as reinforcements for the composite laminates, a hybrid composite comprised of woven glass and basalt fabric that has been impregnated with graphene and seashell nanofillers. The design and composites manufacturing, testing of low-velocity events, nondestructive ultrasonic techniques for assessing damaged composite laminates, and a scanning electron microscope analysis of damage morphology are explained in detail and susceptible to impact during normal maintenance tasks and during operation. The present paper describes experiments performed to determine the way hybrid composites (glass with sustainable seashell filler, and glass/basalt with graphene nanoparticle) respond to low-energy drop weight impact. Hand layup, infusion, and compression molding techniques are utilized to prepare composite. To measure the spread of degradation to the composite at 3 m/s impact velocities, several impact levels of energy between 5J and 48J are involved. At maximum impact force, damage from impact glass/basalt infused with 2wt% graphene of 2mm thickness is 46% higher than that for Glass fiber with seashell filler. With the infusion method and 2.5mm thickness of glass hybrid composite with seashell, filler showed the best weight to impact resistance compared to other samples investigated in this work as well as in our previous works.
