The wear debris of three semi-metallic friction materials reinforced by low carbon steel fiber, brass fiber and pure copper fiber respectively, and grey cast iron couple woren at different temperatures were studied by XRD and EDAX. Wear properties were analyzed together with the surface images got by scanning electron microscope.
