Development of Metalloceramic Friction Materials for Aircraft Brake
C.G.Krishnadas Nair, D.Dutta and G.Mohan

The paper presents the science and technology of designing and developing complex Iron and Copper based metalloceramic composites for aircraft brake applications to meet diverse characteristics such as high co-efficient of friction, low wear rate, high melting point, high temperature strength and hardness, high specific heat and thermal conductivity and resistance to seizure. The composition of the various ingredients and sintering parameters are optimised by statistically designed experiments. Friction test in a laboratory scale dynamometer is used to measure friction co-efficient, temperature rise and wear rate. EPMA and EDAX are used for assessing uniformity of alloying of matrix and distribution of various ingredients. A variety of complex compositions have been developed to suit a number of applications as friction material for aircraft ranging from jet engine trainer, advanced fighter, civil and military transport aircraft.
