Abstract

Increasing demands for lightweight materials in various industries, such as aerospace, automotive, and manufacturing, have led to a growing interest in the development of advanced materials with enhanced mechanical properties. One promising avenue for achieving lightweight and high-performance materials is the fabrication of aluminum-based composites reinforced with silicon carbide (SiC) and graphite (Gr) particles through stir casting. The current study examines the impact strength behavior of composites reinforced with AA6063 cast materials that contain different amounts of micron sized SiC particles and 5 weight percent graphite. By using liquid metallurgy, hybrid composites of AA6063, SiC, and Gr were created. The numerous created samples underwent the customary Charpy impact testing, and the impact strength was assessed. By reinforcing SiC and graphite to the aluminum matrix, a substantial increase in impact strength was observed. For the three test samples, the average impact strength of pure aluminum was found to be 7 Joule. Average Impact strength for aluminum with 10% silicon carbide was found to be 8 Joule, which is 14.28% greater than for pure aluminum. The average Impact strength for the composite of aluminum with 20% silicon carbide was 10 Joule, which represents a 42.85% increase in strength over pure aluminum.
