Investigation of mechanical properties of bronze-basalt fiber reinforced composites used in friction plates

In this study the mechanical properties of bronze composites reinforced with basalt fibers were studied. Basalt fibers are sensitive to the strengthening of the bronze was used in powder metallurgy. Samples were sintered at 850 °C in reducing atmosphere (H2-% 25N2) for 30 minutes. The effects of basalt fibers volume fraction on the friction properties and tensile properties of the composites were investigated. The best tensile and wear properties of basalt fibers is visible in the samples containing 9%. The fracture surfaces of the samples were examined by electron microscopy.
