Effect of Basalt Fiber Content on Mechanical and Tribological Properties of Copper-Matrix Composites

Abstract

The basalt-fiber-reinforced copper-matrix composites were fabricated using spark plasma sintering. The effect of basalt fiber content on the mechanical and tribological properties of copper-matrix composites was investigated. The results show that the relative density decreased, the hardness increased and the tensile strength first increased and then decreased with the increase in fiber content. The optimal tensile strength of 276 MPa was obtained when the content of basalt fiber was 1.5 wt.%. The friction coefficient of the composites decreased, and the wear volume first decreased and then increased with the increase in the fiber content. The addition of basalt fibers reduced the plastic deformation of the copper matrix during the friction test due to its strengthening effect. Moreover, the detached basalt fibers from the Cu matrix were ground into fine particles and were helpful for forming a mechanical mixing layer, which can decrease the friction coefficient of composites.

Experimental Investigation of High Filler Loading of SiO2 on the Mechanical and Dynamic Mechanical Analysis of Natural PALF fibre-Based Hybrid Composite

“…As a result, its storage modulus diminishes rapidly, as does the amplitude of tan. Whenever the SiO 2 levels are excessive (9 wt%), aggregates on the ber surface impede resin-ber interaction, and interfacial bonding is poor, leading to greater energy dissipation [22].…”

“…The physical and dielectric characteristics of a carbon ber insulation sheet were enhanced as a result. Cheng et al found that increasing the silica concentration improved the compression strength of glass-epoxy hybrids [22]. The improved strength of concrete might be ascribed to improved interfacial adhesion caused by the scattered silica nanoparticles.…”

Mechanical Characterization and Static Analysis of Natural Fiber Based Composite Propeller Blade

“…Composites are captivating because to their light weight, relatively inexpensive, great oxidation resistance, and outstanding hardenability [10][11] . Preponderance of these innovative tasks was influenced by the desire to combat issues with corrosion that metallic materials faced 12). During 1950s these composite structures begin to install in the ship and submarines with the length less than 15 m, while lengths have continuously risen over time, all composite naval ships may now reach lengths of 90 meters.…”
