Introduction Particulate reinforced metal matrix composites are considered to be important materials due to their high strength, high stiffness and low density [1].
These include test geometry, load, test duration, materials properties and environmental factors such as temperature, humidity etc.
Frictional materials used nowadays containing conventional organic binding agent exhibit poor frictional stability.
