本文综述了原位反应复合材料的国内外研究现状。现有的反应制备工艺可分为气－固、固－液、液－液、固－固四类，对各种工艺的优缺点分别进行了讨论。分析探讨了原位反应复合材料的研究方向。“,”The article reviews the development of researches on In-situreaction composites. The techniques of the composites can be divided into four kinds, i.e. gas-soid, sold-liquid, liquid-liquid and solid-solid. The advantagses and disadvantages in every tech nique are respectiveiy discussed. In addition the research directions and prospects of In-situ reaction composites are primarily analyzed and discussed.
