| Abstract: | The density,structure,chemical element analysis,mechanical,physical and friction properties of a certain type of aircraft brake material-a beryllium alloy were investigated.A comparison of some performances between C/C composites,C/SiC composites and the Be alloy made by powder metallurgy(PM) was made and the results show that beryllium alloy has low density,excellent mechanical and friction properties,and is a potential brake material. |
