A STUDY OF FC-2 MATERIAL USED FOR FRICTION BRAKE IN AEROPLANES

By suitable controlling the amount of graphite in FC-1 friction materials used for making landing brakes of airplane,the frictional properties and the mechanical strength of the material were therefore a new type of friction material,FC-2, with favourable combination of properties was obtained. It was demonstrated by flying tests for a long period that this material meets the technological reguirements of trident aeroplane. Now it has formally been used in aeroplanes.
