“…The SWR for both 200 and 240 gsm UHMWPE fibre reinforced composite specimens is equal in both the composites; the SWR is decreased with increase in load as is observed from the Figure 8 (a) and 8(b). Similar results were observed by other researchers who worked on similar lines [24][25][26][27]. The effect of layers on the SWR is almost equal for both the composite specimens since the wear of the composite took place only on the outer surface as is observed from the SEM images.…”

Usage of synthetic fiber reinforced composites has increased rapidly because of their excellent properties such that it acts as a replacement for metals in the recent days. The physical and wear properties of Ultra-High Molecular Weight Polyethylene (UHMWPE) fabric reinforced epoxy composites have been studied in this present work. Using pin-on-disc test rig, dry-sliding wear of test specimens have been tested against disc of EN31 steel material. The plain woven bi-directional 200gsm and 240gsm UHMWPE fabric reinforced epoxy composites were fabricated by hand lay-up method at room temperature. All the tests were conducted as per the Taguchi’s L9 orthogonal-array. The process parameters considered in the present study is load, sliding velocity and sliding time with three levels each. Specific wear rate is considered as the response variable. Optimization is carried out to find best combination of parameters on specific wear rate. From the results, it is evident that load has greater influence on specific wear rate than other two considered parameters. Scanning Electron Microscopy (SEM) analysis was also carried out to examine the matrix distribution over fabric (reinforcement) and also their bonding between reinforcement and matrix.

“…Microhardness test involves measuring the hardness of the materials effectively and precisely. Compared to other hardness tests, the Vickers hardness test is the best suited method to measure the hardness, because the accuracy of testing and damage of the specimen is less [15][16][17][18]. In this research, linked to all factors and deep study of literature, the aluminum metal matrix composites are chosen.…”

Currently, the aluminum alloys are utilized more in level of all industries for different applications; furthermore, industries need high-strength alloys for making innovative components. For those reasons, many researchers hope to prepare hybrid aluminum metal matrix composites at various composition levels. In this experimental work, we intended to prepare the hybrid metal matrix composites such as aluminum alloy 7079 with reinforcement of ZrO2 + Si3N4 through stir-casting process. Major findings of this work, as to optimize the stir-casting process, can be to continually conduct wear test and evaluate the microhardness of the stir-casted specimens. Optimization of stir-casting process parameters is a preliminary work for this research by Taguchi tool. The chosen parameters are % of reinforcement (0%, 4%, 8%, and 12%), agitation speed (450 rpm, 500 rpm, 550 rpm, and 600 rpm), agitation time (15 min, 20 min. 25 min, and 30 min), and molten temperature (700°C, 750°C, 800°C, and 850°C). The prepared stir-casted materials are tested by wear analysis and microhardness analysis, through Pin-on-Disc wear tester and Vickers hardness tester, respectively. Wear parameters are optimized, the minimum wear rate is evaluated, and also the wear worn-out surfaces are examined through SEM analysis.

“…The equation is produced in terms of coded factors, and it predicts the response for presented levels of all the factors. The developed RSM model for microhardness was evaluated at a 95% confidence interval for its algorithmic significance [ 53 ]. The coded equation analyzes the coefficients of the variables to establish the comparative effect of parameters.…”

The tenacious thirst for fuel-saving and desirable physical and mechanical properties of the materials have compelled researchers to focus on a new generation of aluminum hybrid composites for automotive and aircraft applications. This work investigates the microhardness behavior and microstructural characterization of aluminum alloy (Al 7075)-titanium carbide (TiC)-graphite (Gr) hybrid composites. The hybrid composites were prepared via the powder metallurgy technique with the amounts of TiC (0, 3, 5, and 7 wt.%), reinforced to Al 7075 + 1 wt.% Gr. The microstructural characteristics were investigated by optical microscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS) elemental mapping. A Box Behnken design (BBD) response surface methodology (RSM) approach was utilized for modeling and optimization of density and microhardness independent parameters and to develop an empirical model of density and microhardness in terms of process variables. Effects of independent parameters on the responses have been evaluated by analysis of variance (ANOVA). The density and microhardness of the Al 7075-TiC-Gr hybrid composites are found to be increased by increasing the weight percentage of TiC particles. The optimal conditions for obtaining the highest density and microhardness are estimated to be 6.79 wt.% TiC at temperature 626.13 °C and compaction pressure of 300 Mpa.
