Over the last few decades, researchers have aggressively investigated natural fibre reinforced polymer composites for replacing conventional synthetic polymeric materials in a variety of applications, including automotive, medical, agricultural, thermal management, and building insulation. In this study, modelling and simulation technique was used to predict the tensile properties of Unidirectional Glass/Epoxy and Arenga Pinnata/Epoxy Hybrid Composite Laminate. The effect of hybridization on the tensile strength of FRP composites was evaluated using ANSYS software based on maximum stress failure criteria. A symmetric finite element modelling of [±θG/±θAP]S hybrid FRP composites were analysed and compared to the properties of [θG/−θG]2S and [θAP/−θAP]2S. Glass/Epoxy and hybrid with Arenga Pinnata/Epoxy natural fibre laminates subjected to uniaxial tension were simulated. The stress of the hybrid laminate composite of natural fibre from Arenga Pinnata yielded a moderate stress value, indicating that the composite was reliable. The maximum tensile stress of fibre laminates with the orientation of 0°, 15°, 30°, 45°, 60°, 75°, and 90° degrees were evaluated. Glass Fibre Reinforced Polymer (GFRP) fibres had the maximum uniaxial tension stress of 342.56 MPa at 0° and 78.38 MPa 30° ply orientation, while both fibres had the lowest uniaxial tension stress of 9.25 MPa and 7.20 MPa, at 90° ply orientation, respectively. Meanwhile, the hybrid of GFRP and Arenga Pinnata Fibre Reinforced Polymer (APFRP) had a tensile property of 264.95 MPa at 0° and 4.53 MPa at 90°. This study contributes new knowledge in predicting the tensile strength value using modelling and simulation techniques. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
