The basic requirements and characteristics of powder metallurgy friction material for airplane were reviewed, including suitable and steady friction coefficient, minimum wear, not felt, good physical and mechanical properties, good temperature property and so on. Weighted analysis method was used for the research of the selection of the friction material for Boeing-737 airplane which was based on these basic requirements, and an iron-copper base friction material suit able for the plane was obtained. The results show that weighted analysis method is an effective method for the selection of basic friction material in airplane.
