  Investigating the Mechanical Properties and Microstructure of AA 7074 Composites with Silicon Nitride Reinforcement

  By V. Ravi Raj, G. Ashwin Prabhu, S. Karthik, Vaddi Seshagiri Rao, SP. Arunkumar, Ameeth Basha I., S. Venkatesan, M. Kalaimani

  Abstract: This study investigates the mechanical and microstructural properties of AA 7074 aluminium alloy reinforced with 1%, 3%, and 5% by weight of silicon nitride (Si₃N₄), fabricated via the stir casting method, intended for structural aerospace applications. A thorough series of mechanical tests—comprising tensile, compression, hardness, impact, flexural, and wear tests—was performed to assess the influence of differing reinforcing content. The composite containing 5 wt% Si₃N₄ (SN5) demonstrated the most pronounced …

  Thermal and Electrical Performance of Aluminum-Reinforced GFRP Composites

  By G. Ashwin Prabhu, M. Babu, S. Prathap Singh, Jagadeesh Bommisetty, Ramya R., Vaddi Seshagiri Rao, Prithvi A., Mohammed Ziberel S.

  Abstract: This work examines an economical approach to improve the thermal load protection of Glass Fiber Reinforced Polymer (GFRP) composites, commonly utilized in aircraft constructions, pressure containers, and electrical insulators. Notwithstanding their superior mechanical capabilities, GFRP composites are susceptible to elevated temperatures and electrical currents, frequently resulting in considerable structural deterioration. The study introduces an innovative method employing aluminum reinforcement to enhance the thermal conductivity and protection of GFRP composite laminates. …
