Abstract

This paper examines the feasibility of utilizing jute-polyester composites as a substitute for glass fiber composites in demanding automotive impact protection. Further, the study focuses on developing accurate modeling procedures using LS-DYNA explicit finite element analysis to predict the load�displacement responses and failures of jute-polyester (JP) composite tubes under static and dynamic loading. Experimental tests validate the model, comparing numerical and experimental results using the Gross Correlation Index (GCI). The GCI ranged from a minimum of 0.83 to a maximum of 0.97. Strong agreement is observed, confirming the reliability of the developed finite element (FE) model. The validated modeling procedures offer insights for optimizing the design and performance of jute-polyester composites, promoting sustainable materials in the automotive sector, particularly for applications related to vehicle interior trims. Highlights: JP composite tubes studied under axial and transverse impact loads Developed accurate modeling procedure using LS-DYNA FE model validated through experimental test results GCI used to compare numerical and experimental results Successful prediction of failure modes and impact parameters. © 2023 Society of Plastics Engineers.
