Fiber glass/carbon hybrid composite laminates have a wide range of uses in machine tools, aerospace, and automotive structures. Many researchers have worked to develop hybrid laminates with the optimal layering arrangement and enhanced static and dynamic stability. In the current work, the influences of fiber orientation and adding SiO2 on the proven effective layering arrangement of a glass/carbon hybrid composite was examined. Three significant fiber orientations 0o , 45o , and 90o were taken into consideration, along with the addition of SiO2 nanoparticles as fillers to epoxy to explore the influence of fiber orientation on the effective layering arrangement. By using the infusion process, all of the hybrid laminates were created. The hybrid composite samples were evaluated for mechanical qualities like tensile and flexural strength for more trials in order to understand and analyze the influence of fiber orientation and SiO2 nano particles. For the tensile and flexural tests, the test pieces have been cut to the standard size set by ASTM. The findings were presented and analyzed. According to the findings, the tensile and flexural strengths increased with increasing the plate thickness and adding the SiO2 nanoparticles.
