Inter Laminar Shear Strength of Flax-Glass Hybrid Polymer Composites for Automotive Frame: Numerical Modelling and Experimental Analysis

Year: 2025

Type: article

Abstract: This study deals with the mechanical performance in the case of hybrid polymer composites developed from sandwiched reinforcements using natural fibre and glass fibre-based fabrics. The composites developed by using different combinations and arrangements of the glass and flax fabrics were tested for the interlaminar shear strength (ILSS). Finite element analysis based on ANSYS was used to determine the ILSS for the hybrid composites. Further, experimental testing of the ILSS was carried out in order to validate the predicted performance. The comparison of simulated values with the tested values showed percentage error values ranging from 0.106% to 6.25%. The minor error between the tested and simulated values can be due to the presence of very small imperfections in the composite, like the presence of voids, which could potentially be introduced in the composite while manufacturing the samples. Microscopic analysis confirmed the fracture in between the layers and interfacial debonding between the fibre and the matrix. It was found that the flax fibre tends to break earlier as compared to the glass component, which has much better mechanical performance. The findings are important for understanding the performance of hybrid composites in real loading conditions in automotive frames and other similar applications.
