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

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