Experimental Investigation of Non-destructive Vibrational Evaluation Techniques for Determining Elastic Properties of Jute and Glass Fiber Reinforced Composites

Recently, natural and synthetic fiber reinforced composites may find application in nearly every sector of engineering. In this study, an experimental analysis of the dynamic features of jute fiber reinforced polymer composites (JFRPC) and glass fiber reinforced polymer composites (GFRPC) for the purpose of estimating Young's modulus is presented. The natural frequency value of composite plates made by JFRPC and GFRPC was measured using impulse excitation technique (IET) experiments. The tensile test, however, was carried out to verify the IET test's results. The findings indicate that the strength of a composite made of glass fibers is noticeably better than that of a composite made of jute fibers. However, the mechanical properties of woven jute composite are equivalent to those of glass fiber composite. This is especially true in regard to its Young's modulus, which is almost identical to that of the glass fiber composite. It is anticipated that this method will be able to predict the mechanical characteristics of other materials and that it will have potential as a non-destructive examination method.
