; Abstract: To improve the oxidation-resistance properties, SiC and TaC species were introduced in C/C composites by chemical vapor infiltration (CVI) methods. The oxidation-resistance properties of C-SiC-TaC-C composites were studied by X-Ray diffractometry (XRD), JEOL-6360LV scanning electronic microscopy......

Technology摘 要:Compared with the first and second generations SiC fibers, the third generation SiC fibers have obvious improvement in heat-resistance, oxidation-resistance and creep-resistance, which promote the development of SiCf/SiC composite materials. Therefore, the third generation SiC fibers have more advantages and broader prospects in engineering......
