As a space deployable structure, the space masts are widely used in the aerospace field. In the article, a new shape memory polymer (SMP) mast structure was designed and the compression folding behaviours of the SMP mast was investigated. The mast can automatic deployment due to the shape recovery characteristics of SMPs. The thermodynamic model of SMPs were realized by the finite element method. The numerical simulation of the fold and deployment process of the SMP mast were carried out, and the geometric parameters (wall thickness) and the influence of temperature on the folding performance of the mast were also investigated. The results contribute to the design and application of novel SMP mast.
