Abaca is a high-strength natural fiber whose tribological behavior in epoxy polymer composite is unexplored to date. This paper aims to study the mechanical and dry sliding wear behavior of abaca fiber (A) and glass fiber (G) reinforced epoxy laminate composites with various stacking sequences. Symmetrically oriented laminate composites were fabricated in different stacking sequences (AAAA, AGAG, AGGA, and GAAG) using hand lay-up technique. Mechanical characterization is carried out as per ASTM standards. It is found that GAAG hybrid composite possesses maximum tensile strength (101.05 MPa). Meanwhile, AGAG composite shows maximum flexural strength (190.15 MPa) and interlaminar shear strength (5.97 MPa). Abrasive wear behavior of the composites is investigated by performing the test on a pin-on-disc tribo tester as per the ASTM G99 standard under dry sliding conditions. Tribological results indicate that hybridization of abaca and glass fiber into an epoxy matrix enhances the wear properties significantly. Maximum wear resistance is observed with AGGA-layered hybrid composite. The reduction in volumetric wear of AGGA composite is found to be lower than neat epoxy by 86.51%. However, the frictional force of AGGA composite increased by 54.17%. Furthermore, the morphology of fractured and worn-out surfaces is studied using a scanning electron microscope. It is inferred that failure is mainly due to the development of micro-cracks on both fiber and matrix, combined with fiber fragmentation, plowing, and debonding.

“…42 Anjum et al observed that the normal load had the most impact on the specific wear rate of the modified sansevieria/carbon fiber reinforced epoxy filled with nano-CaCO 3 composite, whereas the filler loading had the most impact on the specific wear rate of the nano-SiC filled composites. 43 Manjunath and Rao reported that the coefficient of friction and wear rate of glass fiber-reinforced epoxy composites increased with increasing sliding speed and normal load, whereas the wear rate increased with increasing sliding distance. 44 For a range of filler contents (5–40 wt.%), Bhagyashekar and Rao found that the wear resistance and friction coefficient of epoxy composites increased with sliding distance and contact load.…”

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.

“…Taguchi experimental design has been widely used to perform various kinds of tribological tests on metal, polymer and ceramic matrix composites [16][17]. Response surface method is also a powerful statistical and mathematical tool to predict the effect of wear test parameters on the specific wear rate [18][19].…”

In various applications like bearings, gear pairs, and brake pads, understanding how polymer composites interact with harder counterparts during sliding motions is crucial. A challenge arises from the heat generated during sliding friction, which has the potential to raise the contact temperature. This temperature increase, if it exceeds the material's glass transition temperature, can compromise the thermal stability of the composites, leading to rapid material wear. In the present investigation, dry sliding wear test was performed on 25 wt. % of short carbon fiber (SCF) reinforced polyethersulfone (PES) composites filled with 2.5 and 5.0 wt. % of potassium titanate whisker (PTW) using pin-on-disc tribometer. Wear test was planned and executed according to the experiment design formulations obtained by central composite design method. Contact temperature at the interface between composite pin and steel disc was monitored with an infrared thermal camera. Wear resistance was found to increase with the addition of fibers and fillers. PTW filled composites exhibited minimum wear with maximum coefficient of friction. Morphology studies were carried out on worn surfaces of the composites using scanning electron microscope to identify and describe the mechanism of wear involved. This investigation sheds light on the intricate behavior of polymer composites during sliding interactions.
