摘要
采用原位反应法在三维编织碳纤维(原纤维)表面制得β-SiC涂层,通过XRD,SEM,等温氧化失重和非等温热重分析等测试手段研究了制备方法对涂层性能的影响。结果表明:利用此法可得到均匀、完整,界面结合良好的涂层,涂层厚度增加,涂层/三维编织碳纤维(复合纤维)抗氧化性能增强。并对复合纤维氧化反应的机理进行了研究。
The XRD, SEM, isothermal oxidation-weight loss and non-isothermal TG-DTG were used to study the properties of SiC coatings/3-D braided carbon fiber(composite fiber) prepared by in-situ reaction method. The results show that coatings is coated symmetrically and combine well with every fiber of 3-D braids in proper reaction conditions, the oxidation resistance of composite fiber increase with the increase of SiC coatings thickness. The oxidation resistant properties and mechanism of composite fiber were studied also.
