摘　　要：利用相变材料的特性研制含相变物质的复合材料能够起到很好的热控作用,根据目前的研究探索,对于导弹、航天飞行器的热防护有非常好的应用效果。综述了相变材料研究的成果,对热控相变材料进行了新的分类,并阐述了相变复合材料制备方法及应用,阐明了热控应用中选择适宜相变材料的热物性指标以及相变复合材料制备与应用深入研究的方向。Phase transition has the capacity to store thermal as latent heat of fusion at a constant temperature corresponding to the phase transition temperature of the phase change materials （PCMs）. Through this meehanics, phase change composites that gain thermal control can be prepared, which are well applied in the field of thermal protection on the aircraft and missile. This paper reviews previous work on latent heat storage and provides an insight to recent efforts to develop new classification of the PCM for thermal control. Three aspects are the focus of this review： PCM, preparation and applications, which enlighten the research directions of phase change composites for thermal control.
