Betelnut fibres as an alternative to glass fibres to reinforce thermoset composites: A comparative study
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,...

| Summary: | 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 CSMGFRP.
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. |
