Mechanical and Dynamic Behavior Analysis of Nanosilica added Saccharum Munja Fiber Epoxy Composite

This study investigates the mechanical and dynamic behavior of nanosilica-filled Saccharum munja fiber polymer composites. The composites were fabricated with varying nanosilica content (0–5%) and tested for tensile, flexural, impact, and hardness properties. The results show that the addition of nanosilica up to 3% improves the mechanical properties, including tensile strength (250 MPa), flexural strength (220 MPa), impact energy (140 J/m), and hardness (22.5 HRF). The water absorption test reveals that the composite with 3% nanosilica content shows lower water absorption. The thermogravimetric analysis indicates that the nanosilica addition improves the thermal stability of the composite. The free vibration analysis shows that the composite with 3% nanosilica content has higher natural frequency values (25, 144, 326, 520, 888, and 969 Hz) and lower damping factor values (0.060, 0.045, 0.037, 0.036, 0.025, and 0.024). Overall, the study suggests that the Saccharum munja fiber polymer composite with 3% nanosilica content has potential applications in various industries.
