Hybrid reinforced composites can exhibit a huge effect on the tensile properties because of their enhanced stiffness and high strength of the structure when contrasted with fibre reinforced pure composites, which comprise similar materials only. The purpose of this study is to investigate the tensile properties of hybrid jute/roselle woven reinforced polyester composites. The composite's stacking sequences and orientation with different layering numbers of 2 and 3-layer consist of pure jute (J), pure roselle (Ro), and hybridised jute and roselle (J-Ro) composites will be evaluated. The hand lay-up technique method is employed to fabricate the composite specimens test. According to the findings of this study, with the addition of bi-layer of pure woven jute or roselle and hybrid jute/roselle in polyester composites, the tensile strength (TS) has increased from 12% to 41% and 13% to 42% for tensile modulus (TM), respectively. Tri-layer composites are highest TS and TM when jute fibre is applied at the top and bottom of the laminate as skin layers and roselle fibre position in the middle layer, which is attributable to higher elastic modulus tensile strength of jute fibre when contrasted with roselle. This study discovers that the roselle and jute fibres as the reinforcements embedded into the polyester matrix can produce high strength composite materials. Moreover, hybrid jute-roselle composite is suggested to have a higher potential for future development in the industry. © 2023 American Institute of Physics Inc.. All rights reserved.
