“…Because of the dislocation strengthening, aluminium oxide powder reinforcing agents were introduced into the copper to increase mechanical characteristics. As a result, the hardness and strength of the copper metal matrix composite structures were found to be higher than that of pure copper [19]. Te wear behavior of copper metal matrix composites reinforcing with three distinct reinforcing particles, such as aluminum oxide, boron carbide, and a combination of aluminum oxide and boron carbide, using friction stir processing, an intense plastic straining technique, was studied.…”

The current study examines the effect of titanium carbide reinforcement (TiC) on the tribological behavior of copper metal matrix composites. The stir-casting process followed by hot rolling was employed to fabricate the composite parts. Hot rolling was performed at 510°C temperature with a 90% reduction ratio. An optical microscope, scanning electron microscope with energy dispersion spectroscopy, and Brinell hardness tester were used to investigate the microstructure, reinforcement particle distribution, and hardness. The microstructural investigations witness the uniform distribution of titanium carbide reinforcing agents along with the excellent binding with the copper matrix. The hardness was improved with the addition of titanium carbide content in both casting and rolling specimens. Dry sliding friction and wear tests were employed on a pin-on-disk setup with load values ranging from 30 to 120 N and sliding velocity values ranging from 0.628–2.512 m/s. In both casting and rolling conditions, the composites have a less coefficient of friction and wear rate than the matrix element. Wear rates of the unreinforced and reinforced cast and hot rolled alloys were enhanced as load and sliding velocity was raised. The incorporation of titanium carbide lowered the coefficient of friction and wear rate. In comparison to the unreinforced cast and rolled alloys, the coefficient of friction and wear of cast and rolled copper metal matrix composites was significantly reduced. Scanning electron microscopy was employed to investigate the worn surfaces and wear debris to confirm the possible wear mechanisms.

“…The study of hybrid polymers matrix composites is done using different process parameters like tensile strength, electrical conductivity, and thermal expansion coefficient of each composite material. The study of copper surface oxidation resistance property using polymeric molecular coating and study of thermal conductivity and thermal resistance using copper nanoparticle-deposited graphite sheets was done in [1][2][3][4][5]. Islam et al [6] used physics-based computational methods to predict the dielectric properties of polymer nanocomposites; and on the electrical conductivity and dielectric permittivity of graphene-polymer nanocomposites, the influence of temperature and graphene concentration was investigated by Weng et al [7].…”

Hybrid Polymer composites have recently emerged as one of the most important fields for researchers owing to their weight reduction benefits, corrosion resistance, design flexibility, manufacturing developments, multidiscipline applications, and sustainability. There are many types of hybrid polymer composites, one of which is made up of combining natural polymers and synthetic polymers and the other which is made up of combining natural-natural polymers. Hybrid composites also consist of nanocomposites, molecular composites, nanomaterials, and mesoscopic materials. In present study, hybrid polymer matrix composites reinforced with copper particulate were prepared using polycarbonate (PC), acrylonitrile butadiene styrene (ABS), and polycarbonate plus ABS. Injection moulding process employed to synthesize the hybrid polymer composite. Tensile strength, electrical conductivity and thermal expansion coefficient were measured as per the ASTM D638, ASTM D 257 and ASTM D 696, respectively. 50% Copper + 50% Polycarbonate outperform other combinations in terms of tensile strength, electrical conductivity, and coefficient of thermal expansion. In addition, scanning electron microscopy was also used to understand the homogenous mixture of hybrid polymer composites.
