Abstract
My master thesis is Study on the Transient Oxidation of Needle Punched Carbon/Carbon Composites with Multiscale Coupling Method supervised by Prof. C.W. Zhou in Engineering Mechanics department, College of Aerospace Engineering, NUAA. This thesis explored the transient oxidation behaviors of carbon/carbon composites at various scales and their coupling model with the multiscale method.
