Fabrication and Mechanical Testing of Boron, Silicon Carbide and Polyster Fiber Hybrid Composites Reinforced with Graphite Powder

This study explores the fabrication and testing of hybrid composites made from Boron,Silicon Carbide,Polyster Fibers reinforced with Graphite powder and epoxy resin. Using a layering technique, the composites were evaluated for strength, durability, and suitability in engineering applications. Results showed that Graphite Powder enhanced stiffness and hardness, while hybrid fiber composites outperformed single-fiber ones due to better load sharing and fiber–matrix bonding. The Boron+SiC+Polyster Fibers+Graphite Powder hybrid composite exhibited the best mechanical performance when comparing with other results.
