Friction and wear characteristics of Furcraea foetida fiber-reinforced epoxy composites

Abstract

In the current study, the friction and wear properties of Furcraea foetida fiber-reinforced epoxy composites were investigated. This study evaluated the effect of Furcraea foetida fiber content on the tribological behavior of composites. A water-retting method was employed to extract the fibers, and resin transfer molding was used to fabricate the composites. The frictional force, coefficient of friction (COF), and wear rate were measured under dry test conditions and various applied loads (80, 100, 120, and 140 N). Microstructural analysis was conducted using scanning electron microscopy to investigate the surface morphology and wear mechanisms of the composites. The results revealed that the composite with 50 vol% of fibers exhibits the lowest frictional force and COF in both normal and parallel orientations with overall average COF of 0.43 in normal orientation and 0.42 in parallel orientation. Moreover, the composite with 60 vol% demonstrates the best wear resistance with an overall average specific wear rate of 2.1982 × (Formula presented.) in normal orientation and 4.3478 × ((Formula presented.)) (Formula presented.) in parallel orientation. Overall, this study provides valuable insights into the tribological behavior of Furcraea foetida fiber-reinforced epoxy composites and identifies the optimal volume fractions for improved friction and wear performance. Highlights: Higher vol% yields denser composites with minimized voids. Normal fiber orientation shows maximum SWR of 10.0614 × ((Formula presented.)) (Formula presented.). Optimal frictional force and COF in 50 vol% composite. Enhanced wear resistance observed in 60 vol% composite. Higher vol% increases interfacial bonding and wear resistance in composites.
