Modelling for Predicting and Optimizing of the Tensile and Flexural Properties of Sisal/Carbon Fibre Nano-Composite through RSM

The purpose of this study was to examine the impact of fibre orientation on the tensile and flexural strength of composites composed of sisal and carbon fibres, with fibre orientation of 10, 25, and 40°. Furthermore, the research sought to ascertain the optimal parameters for the therapeutic procedure. Response Surface Methodology (RSM) with Central Composite Design (CCD) was utilized to develop and analyze the experiments. The main objective was to optimize crucial elements such as, fibre orientation and the composition of sisal and carbon fibres. This methodology was utilized to construct quadratic models for forecasting the tensile and flexural strength of the composites. The optimal parameters are 60° orientation and a composition of 40% of each fibre. Under these circumstances, the composite exhibited a 34.27% increase in tensile strength and a 22.76% increase in flexural strength when compared to the minimum values obtained from RSM optimization. The notable enhancement demonstrates that the fibre orientation can effectively increase the tensile and flexural strength, as well as improve the adhesion between natural fibres and polymer matrices.
