Continuous sic fiber reinforced titanium matrix composites hold immense potential for advanced aircraft and aerospace structural applications . however , due to the high reactivity of titanium , brittle reactive products at fiber / matrix interface are easy to form and may lead to a degradation of the mechanical properties of sic / ti composites Sic纤维增强ti基复合材料在航空航天领域有重要的应用前景，但由于ti的化学活性大，在复合材料的sic - ti界面处存在严重的界面化学反应，会极大的损害sic ti基复合材料的力学性能。
