| 摘要: |
| 通过对低预氧化程度的聚碳硅烷（PCS）纤维进行热交联处理，降低SiC纤维中的氧含量，经过二步烧成法制备出机械性能及高温耐氧化性能优良的连续SiC纤维。通过IR、 XRD、SEM、元素分析仪等分析手段系统研究了研究了热交联碳化硅纤维的热交联处理的工艺条件、烧成工艺，研究了热交联碳化硅纤维的组成、微观结构及其与纤维的力学性能、高温抗氧化性能的关系。 |

| Abstract: |
| SiC fibers with good high-temperature resistance are prepared by PCS fibers with low oxygen content(LO-PCS) through thermal cross-linking(TC) reaction.The sintering of the LO-PCS with two steps and the condition of the reaction is studied by element analysis、IR、XRD、SEM. And the relation between the structure and the properties of the fibers are systematically studied. |
| Keywords: thermal cross-linking low oxygen content SiC fibers |
