Hybrid composites development is essential in the current era to achieve the higher mechanical properties at light weight required for various applications. The selection and optimal inclusion of reinforcing elements are crucial to obtain desirable enhancement in the mechanical properties without any effects. The current research is aimed to develop aluminum hybrid composites and study the influence of reinforcing elements on their mechanical properties through experimental investigations. The stir casting technique is used to produce hybrid composites and fly ash, marble dust selected as reinforced at different weight fractions such as 1, 3, 5 and 7% to the AA7068 metal matrix. The mechanical properties such as hardness, tensile, and impact strength are investigated experimentally and found specimens with 7 wt.% exhibited more significant improvement than the others. The hardness by 44.11%, the tensile strength by 45.87%, and the impact strength by 89.67% when compared to AA7068 without reinforcement. The microstructural analysis is performed by applying EDS, SEM, XRD techniques and obtained results are discussed well with suitable illustrations.
