The Effect of Tertiary Ceramic Particle Reinforcement on the Mechanical Characteristics of Hybrid Composites Based on Al7029

Lightweight composite materials, renowned for their adaptability and exceptional properties, are being extensively adopted across several industries. This study investigates the impact of introducing tertiary ceramic particles to hybrid composites made with Al7029 as the matrix material on their mechanical properties. The use of B₄C, Gr, and Si₃N₄ as ternary reinforcements is intended to improve the mechanical properties of the matrix. The process consisted of creating hybrid composites by combining an Al7029 matrix with tertiary ceramic reinforcement. The mechanical characterization involved conducting tests to determine the tensile and compression strength, evaluating impact resistance, examining fractography, and inspecting the microstructure. The results demonstrate substantial enhancements in mechanical characteristics, such as increased tensile strength (32%), compression strength (44.16%), and impact resistance. Fractographic study uncovers unique features of fracture surfaces, providing insight into the manner of failure and the mechanisms that initiate cracks. The work highlights the effectiveness of using tertiary ceramic reinforcement to improve the mechanical properties of hybrid composites made from Al7029. This provides important insight for designing new materials and engineering applications.
