“…Under an applied load of 140 N, SEM analysis of the worn surface revealed the presence of surface cracks, plastic deformation, and loose abrasive particles. Plastic deformation can change the surface topography, creating roughness that increases the contact area and frictional force between the composite material and counterface, leading to higher wear 64 . The loose abrasive particles act as a third body in the wear process, reducing the direct contact between the surfaces and frictional force.…”

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 × in normal orientation and 4.3478 × () 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 × () . 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.

“…The evolution over time of the friction coefficient size can be put in a certain correlation with the evolution during the running-in period of the magnitude of a roughness parameter that takes into account the asperity heights of the investigated surface, such as the roughness parameter Ra. It is thus known that, during the running-in period, regardless of the initial value of the roughness parameter, the heights of the asperities decrease or increase until they reach a value judged to be appropriate for the operating conditions of the joint, after which the heights of the asperities remain somewhat constant for a long time, that is, until the occurrence of catastrophic wear is signaled [49,50].…”

The surfaces of the mechanical parts involved in friction processes are made using different processing methods. Each of these processing methods leads to a certain profile of the asperities of the generated surfaces. When such surfaces are subjected to friction processes, it is possible to produce a change in time in the magnitude of the friction coefficient. For experimental research, the outer cylindrical surfaces of some steel test samples were generated using various machining methods such as turning, grinding, ball and diamond burnishing, and vibroburnishing. Later, using a device adapted to a lathe, experimental tests were carried out following the time variation of the value of the friction coefficient under conditions of dry friction and lubricated friction, respectively. The results of the experimental tests were processed mathematically, being determined by empirical mathematical models that highlight the influence of the final processing methods of the surface, the presence of the lubricant, and the test duration on the variation of the friction coefficient. It was found that first, there is an increase over time in the values of the friction coefficient, and then the values of this coefficient stabilize at certain values. The increase in the coefficient of friction until reaching the stabilization value takes place in a proportion of approximately 148–305%.
