Predicting the elastic properties of hemp fiber - A comparative study on different polymer composite

The present paper reported a comparative study on the prediction of elastic properties of hemp fiber reinforced polymer composite. In this study, polystyrene and epoxy are considered as a matrix while hemp fiber is considered as reinforcement. Elastic properties were predicted for hemp fiber epoxy and hemp fiber polystyrene reinforced composite with respect to the volume fraction of the fiber using Rule of mixture, Halpin-Tsai and Nielsen elastic model. Finally, the elastic properties of hemp fiber epoxy composite and hemp fiber polystyrene composite were compared upto a fiber volume fraction of 80%. Results revealed that hemp fiber epoxy composite predict higher values of elastic properties for all the analytical models. It is seen that hemp fiber epoxy composite predicts higher values of longitudinal Young's modulus (56.69 GPa) than hemp fiber polystyrene composite (56.66 GPa) at 80% volume fraction. Out of all the analytical models, Nielsen elastic model predicts higher values of transverse Young's modulus and in-plane shear modulus for hemp fiber epoxy composite. Also, prediction of in-plane Poisson's ratio seems to be higher for hemp fiber epoxy composite for all the models. Copyright (c) 2021 Elsevier Ltd. All rights reserved.
