SiC/SiCN ceramic matrix composites (CMCs) are promising candidates for components of aero-engines. To evaluate the properties of these CMCs under realistic conditions, a quasiflat panel with effusion cooling holes was investigated in a high pressure combustor rig. A Tyranno SA3 fabric based SiC/SiCN composite with high strength and fracture strain was manufactured via polymer infiltration and pyrolysis (PIP) process. Due to its weak matrix no fiber coating was necessary for damage tolerant behaviour. The cooling holes in the panel were introduced via laser drilling. An outer coating of CVD-based SiC was finally applied for enhanced oxidation resistance. The specimen was tested in the combustor rig. Temperature distributions and cooling effectiveness were evaluated. The macrostructure and coating quality were evaluated via CT scans before and after the combustor test. Local microstructure modifications were observed after laser drilling and coating. No crack formation was observed in the CMC panels.
