ABSTRACT Sisal fibre reinforced epoxy composites are the subject of this study, which intends to evaluate the influence of fibre orientation on the interlaminar shear strength and thermal parameters of these composites. When it comes to defining the mechanical and thermal performance of natural fibre reinforced polymer composites, the orientation of the fibres is a significant factor, as established by the examination of the current literature. There have been observations that the overall qualities of the composite can be improved by the hybridisation of sisal fibre with other reinforcements, such as glass or carbon fibres. Insights into the ideal fibre orientation that can maximise the interlaminar shear strength and thermal stability of the sisal fibre reinforced epoxy composites are anticipated to be provided by the result of the experimental investigation. Due to the influence of sisal fibre orientations such as 0/90°, 90°, and ± 45° orientation, an experimental investigation was carried out in order to assess the ILSS and thermal property of the material. According to the findings of this research, the orientation 90° demonstrates superior ILSS of 5.531MPa and thermal property 0.396 W/m*K of in comparison to the orientations 0/90° and ± 45° for the same purpose.
