The buckling resistance of cylindrical press hull is studied by using functionally graded composites based on carbon nanotube reinforced composites (CNTR) and graphene reinforced composites (GPLs) in the paper. The constitutive equation of CNTR-GPLs functionally graded composite materials （FGM） and the stability equation of cylindrical press hull were established. The effects of geometric and material parameters on the buckling resistance of cylindrical press hull are discussed. The results show that the structural stability can be improved by reasonable design of different material parameters.
