摘　　要：形状记忆聚合物（SMP）是一类新型功能材料,具有密度低、质量轻、形状回复率高及成本低等众多优点,但其刚度较低,形状回复力较小,因此众多研究者对增强SMP复合材料开展了研究.综述了增强SMP复合材料国内外的研究进展,重点分析了短纤维增强、颗粒增强、纤维与颗粒混合增强等不同增强方式对SMP性能的影响,总结了增强SMP复合材料目前所存在的问题,并对其发展方向进行了展望.Shape memory polymer （SMP） is a new type of functional materials.SMP has lots of advantages such as low density,light weight,high shape-recovery rate and low cost,but its stiffness is low and shape recovery force is small.Therefore,the reinforced SMP composite has become a hot research focus.The latest progress of reinforced SMP composite is reviewed,with the emphasis placed on the analysis of the influence of reinforced materials on SMP properties including short fibers,particles and the mixture of fibers and particles.Finally,problems exist in the study and the prospect of reinforced SMP composite are discussed briefly.
