“…DOE by the Taguchi method is favored in research because the design of orthogonal arrays reduces the number of experiments required to study the effect of different parameters on the output 18–21 . Research studies to evaluate tribological properties such as wear rate and COF are very time consuming as they require repeated experiments.…”

This study focused on the wear behavior of unidirectional, thick GF epoxy composites produced using the autoclave method. The thermal aging process was applied for 250 and 500 cycles to understand the wear behavior of the material as it ages over time. To evaluate the wear behavior of the samples, wear tests were carried out under three different loads (10, 20, and 30 N) and three different sliding distances (150, 300, and 450 m). Taguchi‐based regression analysis was used to analyze the experimental results. The results obtained were evaluated using ANOVA tables and main and contour graphs. When the test results are examined, it is surprisingly observed that the wear resistance of the composite material increases positively with the aging effect. With thermally aging while the coefficient of friction value of composite samples increases from approximately 0.12 to 0.3, the wear volume decreases from approximately 4 to 1.3 mm3. Taguchi based regression analysis showed that the relationship between wear and thermal cycle sliding distance and load can be established by reducing the number of experiments in wear studies.Highlights Thermal aging effect on wear properties of thick GFRP was determined. Minimum wear volume and COF values were determined by applying ANOVA. It was determined that a load increment has the most impact on wear volume. Worn surface images supported the reduction in the wear rates of the thick GFRP. Empirical regression models developed for the mathematical prediction.

<div class="section abstract"><div class="htmlview paragraph">The main aim of this experimental study is to investigate the wear properties of a hybrid composite material composed of a banana fibre mat, rice husk powder, and an epoxy matrix polymer filled with multi-walled carbon nanotubes (MWCNT). This research emphasizes the assessment of the composite's characteristics and behaviour. The adjustment of various ratios of fibres and fillers within polymer matrix hybrid composites finds application in numerous engineering fields, particularly in the automotive and aerospace industries. The experimental evaluation is conducted using a pin-on-disk wear tester to analyze the specimens in terms of pin wear, friction coefficient, and friction force. Experimental trials were conducted using L<sub>9</sub> orthogonal arrays following the Taguchi design of experiments, and the output response was optimized by implementing a hybrid approach of Gray relational analysis. It depends upon the suitability of the wear performance needs of the application to obtain the optimal range of use and study of ANOVA software. The ideal conditions have been attained to minimize wear, coefficient of friction, and friction force. After the testing, the specimen's scanning electron/optical microscope images illustrate the wear and primary wear mechanisms. Confirmed experiments with optimal conditions show that the results are closer to the expected results.</div></div>
