“…Similar to other combinations the mixing of hybrid natural fiber composites increased wear resistance due to better adhesion of the matrix/fiber phase. It was also found that an increase in hardness resulted in decreased wear rate in the epoxy‐based natural fiber composites 23,33 . The highest wear rate of 17.99 × 10 −5 mm 3 /Nm was observed with 30 wt% natural fiber composites at 500 m SD.…”

Wear testing, in this research was conducted for compression molded flax and ramie fibers with epoxy resin matrix. The 40 wt% fiber combination was used for a fiber length (FL) of 0.5–1.5 cm while varying sliding distance (SD) ranged from 500 to 1500 m. Better results were obtained in 1000 m SD and 1 cm FL with a specific wear rate (SWR) of 13.12 × 10−5 mm3/Nm. Samples with 50 wt% natural fiber combinations were tried with different FL (0.5–1.5 cm) and sliding speed (SS) from 0.5 to 1.5 m/s. Sliding speed increased the contact between the sample and the counter steel disc, which caused high wear rate in the specimen. A high SWR was observed for the combination of SS 1.5 m/s, 0.5 cm FL due to high contact and with lower adhesion of fiber/matrix phase than in the others. Higher FL damages the compatibility of matrix/reinforcement phases, which makes the epoxy sample highly brittle with less wear resistance. The combination of 30 wt% natural fiber with FL (0.5–1.5 cm) and load 5–15 N showed high wear rate at a higher load of 15 N (31.57 × 10−5 mm3/Nm). SEM results with 50 wt% NF combination, 0.5 cm FL at 5 N load showed high deformation in the natural fiber structure compared to the 40 wt% NF combination, mainly due to the adhesion of fiber with epoxy resin which acted as a stress transfer area allowing transfer of more loads.

“…49 Using Taguchi-based gray relational analysis, Kamaraj et al noticed that the sliding speed had the most prominent impact on the graphene nanoplatelets-epoxy composite's wear property. 50 Talib et al demonstrated that inserting fibers into an epoxy polymer matrix affects the epoxy's tribological characteristics. 51 Using the gray relational technique coupled with principal component analysis, Shahapurkar et al observed that the crump rubber concentration was a significant factor that affected the wear characteristics of the epoxy-based composite.…”

Wear parameter optimization is critical for the successful use of materials in load-bearing applications. This study examines the optimization of various wear parameters using the Taguchi technique for the determination of the specific wear rate of alpha-manganese dioxide (α-MnO2)-epoxy nanocomposites. Four factors viz. wt.% loading of α-MnO2, sliding distance, sliding velocity, and normal load, were selected as controllable factors and a suitable L16 orthogonal array was chosen for conducting experiments. An X-ray diffractometer and field emission scanning electron microscope were used to examine phase identification, surface morphology, and chemical composition. With the addition of α-MnO2 in the epoxy, the tensile stress is decreased, while the elastic modulus is increased. The Taguchi result shows that the wear test in optimal condition is carried out with a wt.% loading of α-MnO2 of 0.5%, a sliding distance of 500 m, a sliding velocity of 1.5 m/s, and an applied normal load of 5 N. Analysis of variance shows the wt.% loading of α-MnO2 has the most influential parameter on specific wear rate with a contribution of 87.94%. The analysis also shows that the general linear model accurately describes the effect of sliding wear parameters on specific wear rates. The Monte Carlo simulated model shows that the experimental signal-to-noise ratios are consistent with the simulated model values. The confirmation test result shows that the % error between the predicted and experimental values of the specific wear rate at the optimum level combination is 4.67%. The worm surfaces of different trial runs show that the material removal process is caused by crack propagation. High-resolution scanning electron microscopic images of fractured surfaces show the formation of a stable tribo-layer at 0.5 wt.% α-MnO2 loading resulted in a significant decrease in the specific wear rate of the sample.
