Traditional mechanical deployable structures usually have such drawbacks as the complex configuration, the large mass, and the inevitable vibration during deployment. However, shape memory polymer composites possess many advantages like low cost, low density, high strength⁃weight ratio, steady recovery process, and small vibration, which provides possible solutions to the problems that current deployable structures are facing. In this paper, the recent advances of deploy⁃able structure based on shape memory polymer composites were presented. Considering the simple configuration and small vibration, the shape memory polymer composites are expected to have more applications in space in the near future.%传统的机械式可展开结构往往存在机械结构较复杂、质量较大、展开过程易产生振动的缺点，而形状记忆聚合物复合材料具有低成本、低密度、比强度大，展开过程平缓，振动小的特点，这些特点使其成为解决空间可展开结构现在面临问题的一种可能手段。介绍了基于形状记忆聚合物复合材料的空间可展开结构的发展近况，其结构简单、振动小等特点有望使其在未来的航天领域得到更多的应用。
