Investigation of Ultra-High Temperature Stability of C/SiC-UHTC Composite via Oxyacetylene Torch Test |
| 초록 |
Ultra-High Temperature Ceramic (UHTC) is a promising refractory material for military and aerospace fields such as weapons and hypersonic vehicle. It shows high performance against oxidation and ablation based on its high melting temperature. The carbide and boride ceramics and their composites are well-known as UHTC and there are many researches on them to achieve excellent stability against the harsh environment of thrusting system. However, the single component UHTC has a weakness on thermal shock that induces micro-cracks. In this study, the carbon fiber reinforced silicon carbide ceramic matrix which is light and has high mechanical strength is introduced to overcome the drawbacks. UHTC powder was added in C/SiC matrix to prevent oxidation of carbon fiber and CVD-SiC and ESD-carbon coating were layered up to maximize the high temperature endurance. The stability of C/SiC-UHTC composite has been tested under an oxyacetylene torch flame for up to 5 minutes. |
