摘　　要：反应熔渗工艺(RMI)制备改性C/C复合材料由于具有工艺周期短、工艺成本低、产品致密度高等优点而受到广泛关注.但是传统反应熔渗中存在基体熔渗损伤和熔渗剂残留等问题,影响复合材料性能.为进一步提升熔渗材料的性能,国内外学者针对低温熔渗方法存在的问题开展了大量研究的工作,本文主要从反应熔渗原理、熔渗工艺影响因素等方面对低温反应熔渗法进行了综述,并介绍了低温反应熔渗技术在熔渗组分、致密化工艺等方面的研究进展,最后指出了目前反应熔渗工艺存在的问题和研究方向.Reactive melt infiltration(RMI)has attracted much more attentions for its advantages of simple processes,low cost,high density and so on,are expected to become the optimized preparation method of matrix modified C/C composites.However,in traditional reactive infiltration,the main problem including the matrix infiltration damage and the residual of infiltration agent affect the properties of composite materials,especially in the ablative resistance.In order to further enhance the performance of reactive infiltration materials,scholars worldwide have undertaken substantial investigations into low-temperature infiltration techniques.In this paper,the aspects of infiltration principle and the influence factors is reviewed.At the same time,the research progress of RMI at relative low temperature in melting components and densification process is summarized.The result shows that Using alloy instead of pure metal as the fusion agent can effectively reduce the reaction fusion temperature and improve the high temperature performance of the composite.Finally,the existing problems and research directions of reactive melt infiltration are pointed out.
