In general, these materials exhibit certain amount of scatter in their properties due to different factors.
Recently, a class of composite materials viz., FGMs has drawn much attention in many engineering applications.
The mechanical response of systems depends on external stimuli and the materials used for their fabrication.

Friction and Wear Characteristics Cu-based P/M Brake Friction Materials with Addition of Fe and C 1,2,aR.J.
Introduction Powder metallurgy (P/M) friction materials are normally classified into three types; namely Cu-based, Fe-based and Cu-Fe-based materials [1].
Cu-based P/M friction materials were prepared and the effects of Fe and C friction components on the COF and wear behaviors of the materials were studied and discussed in this work.
