| 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. |
