Investigation on Ablation Behavior of Cfrc Composites Prepared at Different Pressure

Low thermal conductivity and high thermal stability are desirable for the materials due to their characteristic roles in ablation resistance applications (e.g., reentry parts and renewable rocket nozzles) [1]. Ablation is defined as an erosive phenomenon with a removal of material by a combination of thermomechanical, thermochemical and thermophysical factors due to the high temperature, pressure and velocity of combustion flame [2]. A rocket nozzle, a typical ablation material is often experienced to severe environment. Under these extreme conditions it is obvious that the superior properties of CFRC composites can take advantages and it has been proved the effectiveness of the composites on ablation resistance [3].
