Abstract

The present study aims to develop hybrid jute-hemp fiber/epoxy composites by the hand lay-up process with 60% of fiber reinforcement and 40 % of matrix ratio. To measure the change of tensile properties, prepared hybrid composites were tested for normal tensile strength and edge notch tensile (ENT) test as per the ASTM standards. Findings show that, developed composites with reported tensile strength followed by comparing it with fracture toughness. Experimentally, tensile strength of the developed composite was measured around 31MPa and fracture performance measured using ENT test value approximated as 4MPa which showed its application in moderate structural and semi-structural functionalities. Tensile test data were used to train a polynomial regression model used to predict load-displacement behaviour and the results were good as demonstrated by residual error analysis and actual over predicted plot. The tensile behavior was well predicted using the polynomial regression model as evidenced by the convergence of the training loss curve and distribution of the prediction errors evident in the plots. The study also plays a part in the design of environmentally friendly material combinations as it proves that natural fiber hybrids can also help reduce the over dependency of utilization of synthetic reinforcements and reduction in the cost.

Keywords: ENT test, Tensile Test, polynomial regression, Hemp-Jute composite, tensile properties.
