Optimizing the tensile strength of bismarck palm fibre and cashew friction dust particle reinforced epoxy composites

Abstract

In recent decades, most manufacturing industries have shifted their focus to the production of environmentally friendly components because of environmental concerns and an understanding of the advantages that natural fibres provide. Because of this, a study was conducted to assess the impact of fibre length, fibre volume fraction, and particle size on the tensile strength of epoxy composites reinforced with Bismarck Palm Fibre (BPF) and Cashew Friction Dust (CFD) particles. Response surface methodology (RSM) was employed to design experiments and analyze responses. The fibre length of 22 mm, fibre volume fraction of 25%, and CFD particle sizes closer to 420 µm were found to be the optimal values for the optimal tensile strength of BPF and CFD particle-reinforced epoxy composites. The BPF and CFD particles-reinforced epoxy composites have a highest tensile strength of 34.71 MPa. According to the analysis of variance (ANOVA), the strength of BPF and CFD particle-reinforced epoxy composites is considerably influenced by fibre volume fraction, fibre length, and CFD particle sizes. A significant degree of connection between the actual and predicted values of the tensile strength of BPF and CFD particle-reinforced epoxy composites was discovered after validation experiments were conducted.
