Effect of Different Stacking Sequences on the Mechanical Properties of Jute/Aramid/Glass Fiber Hybrid Composites

Composite materials combining aramid, jute, and glass fibers offer a unique combination of properties such as high strength, impact resistance, and cost-effectiveness. The stacking sequence of these fibers in a composite plays a crucial role in determining its mechanical behavior. This study aims to investigate the effect of stacking sequence on the tensile strength, flexural strength, and hardness properties of hybrid composites. In this experimental study, hybrid composites were fabricated using different stacking sequences of aramid (A), jute (J), and glass (G) fibers. Five specimens were prepared using a hand lay-up technique. Tensile strength, flexural strength, and hardness tests were conducted according to ASTM D3039, ASTM D790-17 and ASTM D2583 standard testing procedures. The results revealed that the stacking sequence significantly influenced the mechanical properties of the hybrid composites. Sample S2 (G/J/A/A/J/G) obtained the highest value of tensile strength and hardness with 188 MPa and 89 MPa respectively while sample S1 (J/G/A/J/G/A) achieved the highest flexural strength with 351 MPa. It is also found that the tensile strength and flexural strength are not interdependent.
