连续碳化硅纤维热交联工艺研究

Study of Thermal Curing Process of Continuous Silican Carbide Fibers

采用热交联工艺改进传统的空气不熔化工艺,在尽可能少引入氧的情况下实现聚碳硅烷纤维的不熔化处理,降低连续SiC纤维中的氧含量。通过IR、元素分析、SEM、XRD等手段系统研究了热交联工艺条件对纤维氧含量、结构、性能的影响。

Thermal Curing process was adopted to improve the traditional air-process to lower the oxygen content of continuous silican carbide fibers by leading oxygen as little as possible to the fibers during their curing treatment. The influence of the thermal curing process on the oxygen content of the fibers, the structure and properties of fibers were systematically studied by means of IR, EA (Element Analyse), SEM and XRD.
