Abstract: The burning rate enhancements of C 60 , fullerene soot (FS) and carbon black (CB) for the combustion of catalyzed RDX CMDB propellants were studied The results show that the burning rate of catalyzed RDX CMDB propellant was enhansed when adding 0 3% C 60 FS or CB respectively Among three carbon substances, the burning rate enhancement of FS was the best With the increasing of the content of FS and CB the values of the burning rate enhancement efficiency Z increased Finally, the enhancement results of carbon substances with various appearances were discussed
