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。
The traditional mechanical expandable structure often has the shortcomings of complex mechanical structure, large mass and easy vibration during deployment, while the shape memory polymer composite has the advantages of low cost, low density, large specific strength, smooth deployment process, small vibration These characteristics make it a possible solution to the problems now faced by space-expandable structures. The development of space expandable structures based on shape memory polymer composites is introduced. Its simple structure and small vibration are expected to make it more applicable in the future spaceflight field.
