Abstract: According to different influences of various friction components on the friction and wear properties of materials and via the investigation and testing of the properties including friction,wear,anti-clamping by adding Cu, Ni, Mn, Mo, and C as basic components, MoS₂, BaSO₄, Sn and Ph as lubricants and SiC, Al₂O₃ and SiO₂ as friction components, the iron base braking materials for Y7 aircrafts have been successfully developed. It has been proved by simulating test on land, trial flying and airline Performance for a long time, that the materials have excellent friction and wear properties and their Performance duration can be increased by more than 3 times in comparison with that of original copper base friction materials.
