Abstract

For the current work, investigations were carried out using treated betelnut fibre-reinforced polyester (T-BFRP) and chopped strand mat glass fibre-reinforced polyester (CSM-GFRP) composites. Results revealed that T-BFRP showed competitive performance of about 1.16%, 17.39% and 4.92% for tensile, flexural and compression tests as compared to the latter. Through tribological performance tests, T-BFRP composite showed superiority in wear for the dry and wet tests of about 98% and 90.8% while the friction coefficient was reduced by about 9.4% and 80% respectively. The interface temperature was lower by about 17% for T-BFRP composite subjected to dry test as compared to CSM-GFRP. SEM analysis revealed that the brittle effects observed on glass fibres during the tribo test enhanced the material removal rate which increased the thermo-mechanical effects at the rubbing zone. As such, evidence of adhesive to abrasive wear transition was observed when the CSM-GFRP composite was subjected to the stainless steel counterface. On the contrary, T-BFRP composite formed a thin layer of shield (i.e. back film transfer) on its worn surface during the test, which assisted in lowering the material removal rate.
