Shape memory polymer(SMP) is a class of smart materials used in intelligent biomedical devices and industrial
application as sensors or actuators for their ability to change shape under a predetermined stimulus. Carbon nanotube
(CNT)/shape memory polymer (SMP) composites demonstrate good mechanical properties and shape memory effect. In
this work, a model of CNT/SMP composite shell with a vaulted cross-section was established. This composite shell
structure could further elevate the recovery stress of CNT/SMP composites. The folding properties of CNT/SMP
composite shell structure were analyzed by finite element method and the influence of structural parameters on the
buckling behavior of the shell was studied using the energy conservation principle. The results indicate that vaulted
cross-section shell had unique mechanical properties. The structural parameters, such as the vaulted radius and the total
length have a great impact on buckling moment of the shell. This shell structure is expected to achieve effective control
of buckling and deploying process, relying on the special shape memory property of SMP and high elastic modulus
CNTs. Moreover, it could also largely avoid the vibration problem during the deploying process.
