Shape memory polymer (SMP) mandrel, a kind of mandrel for fabrication of composite structures, has attracted great attention due to the advantages of low cost, simple operation and easy demoulding. In this paper, a type of styrene-based SMP with good shape retainability and recoverability were synthesized and examined by uniaxial tensile test and dynamic mechanical analysis test. Then, a bottle-shaped...
Styrene-based shape memory polymer (SMP) tubes were fabricated and their basic mechanical properties in different deformation states were investigated. The tensile, compression, bending and twisting shape memory properties of the tubes were analyzed and discussed, and the results indicated that SMP tubes exhibit good shape fixity ratio and shape recovery ratio. In addition, the shape recovery behavior...
