Investigation on Physicomechanical, Tribological and Optimality Condition for Coir Filler-Reinforced Polymeric Composites

This article speculated the physical, mechanical, tribological, and surface morphology of the coir filler-reinforced polymeric composite. The investigation has been carried out regarding different weight percentages (2.5%, 5%, 7.5%, 10% and 12.5%) of coir filler. Moreover, a novel framework for inferring the optimal reinforcement condition of coir in epoxy resin has also been proposed in the form of Schweizer–Sklar fuzzy TOmada de Decisão Interativa e Multicritério (TODIM) approach. The proposed framework is reliable as it does away with the expert's biased evaluations and gives due consideration to their risk appetite. The optimal reinforcement condition has been deduced with due consideration to tribological, tensile, flexural and fracture properties of the fabricated composites. Through the investigation, it has been observed that the polymeric composite fabricated using 5 wt.% coir filler yields the most favourable results with regard to the considered mechanical and tribological properties.
