Mechanical performance evaluation of hybrid carbon and glass fiber reinforced epoxy composites

The aim of this study was to examine the mechanical characteristics of hybrid fiber-reinforced composites. In this study, Glass fiber and carbon fiber were with epoxy resin to produce a hybrid composites. The composites were made through a hand lay-up process, followed by curing under room temperature. The hybrid fiber composites were prepared in a laminated form, with alternating layers of carbon and glass fibers embedded in the epoxy matrix. The fibers of glass were treated with a 5% rinse with distilled water after two hours in a NaOH solution, and compared against untreated fibers. The treatment process was found to improve the fibers’ mechanical properties. Single Fiber Tests were conducted for both treated and untreated glass fibers, with treated fibers showing superior performance. The results demonstrated that the hybrid composites exhibited improved mecha. The fabricated laminates were then subjected to mechanical testing to evaluate characteristics include hardness, flexural strength, impact resistance, and tensile strength. Specimen preparation and testing were performed according to ASTM standards: ASTM D256 is for impact testing of technical properties, ASTM D790 is for flexural testing, and ASTM D638 is for tensile testings, with treated fibers contributing to enhanced tensile and flexural strength, as well as better impact resistance and hardness.
