Oxidation Behavior of Continues SiC Fibers in Static Air
Liang Li, Ke Jian, Yifei Wang
This paper studied the oxidation behavior of the Nicalon and Hi-Nicalon type of continuous SiC fibers. The fibers were exposed in air at 1000-1400°C for 1h. Experimental results indicate that both Nicalon and Hi-Nicalon SiC fibers’ tensile strength decrease, whereas oxygen content increase with rising...
