弹性记忆复合材料(Elastic Memory Composites,EMCs)作为空间可展开材料,近年来受到高度关注。由于EMC采用形状记忆聚合物(Shape Memory Polymers,SMPs)作为基体,在其热激活状态下允许出现更高的折叠应变而不对材料本身造成任何破坏。因此,在空间可展开结构如太阳能阵列等中具有广阔的应用前景。与高性能碳纤维小于1%的极限应变相比,EMC材 Elastic Memory Composites (EMCs), as space-expandable materials, have drawn much attention in recent years. Because EMC uses Shape Memory Polymers (SMPs) as a matrix, it allows higher fold strains in its thermally activated state without any damage to the material itself. Therefore, it has broad application prospects in space-deployable structures such as solar arrays. Compared with the ultimate strain of less than 1% of high-performance carbon fiber, EMC material
