Effect of fiber orientations and their weight percentage on banana fiber-based hybrid composite

Abstract In this era, composite materials made of natural fibers are gaining the attention and interest of researchers, scientists, and engineers due to their impeccable features in contrast to synthetic fibers. Composite materials can be easily modeled and produced in various dissimilar forms as per the need. In this study, four different composite samples were prepared using three distinct fibers; two natural-banana (B) and sisal (S) and one synthetic-glass (G), by varying the weight percentage of banana and sisal. For each sample, the stacking sequence of the fibers are (B-G-S-B), (S-B-G-S), (G-B-B-S), and (B-S-S-G), oriented at (900,+450,−450,900) and put through a uniform point load. So, a total of sixteen composite samples were evaluated for directional deformations, stresses, and rotations using ANSYS Mechanical APDL 15.0. The outcome obtained showed that the arrangement of fibers in the sequence sisal-banana-glass-sisal (S-B-G-S) at different orientations is superior in terms of toughness and distortion resistance in contrast to all the sixteen arrangements.
