Development and Investigation of Biodegradable Hybrid Fiber Sandwiched Composites Using Ultrasonication

ABSTRACT Lightweight and highly strong polymer composites are popular and used in a variety of industries, such as consumer products, electronics, packaging, healthcare, textiles, and aviation. This study examines the production of hybrid polymer nano composites (HPNCs) and their mechanical and physical characterization. HPNCs were developed by embedding eight layers of bidirectional Banana and Kevlar fiber along with nano‐graphene oxide (GO) and epoxy as the matrix material. The novelty in this research was done by employing an ultrasonication machine for uniform dispersion of nano‐sized GO particles and varying the stacking sequence of fiber (KKBKKBKK) followed by variation in GO (0, 0.25, 0.50, 0.75, and 1) wt.% in HPNCs. The optimum values of various mechanical properties such as flexural strength, tensile strength, hardness, and inter‐laminar shear strength were found for the 0.50 wt.% of GO which are 532.13, 552.42, 88.12, and 53.08 MPa, respectively. The optimum impact strength of 878.87 J/m was obtained at 0.25 wt.% of GO. Densities, void content, and water absorption tests were done under physical characterization. The surface morphology and homogeneity of HPNC were done using the FE‐SEM test.
