In the R & D of the Research Institute of Advanced Materials Gas-Generator (AMG) program, an evaluation of the applicability of the SiC^F/SiC composite to the combustor liner on the basis of an evaluation of its mechanical properties and stress analysis of a SiC^F/SiC combustor liner was carried out, and trial SiC^F/SiC combustor liners, the largest of which was 500mm in diameter, were fabricated by the braiding and PIP (polymer impregnation and pyrolysis) method. Using a SiC^F/SiC liner built to the actual dimensions, a non-cooling combustion test was carried out and even when the gas temperature was raised to 1600℃ (1873K) at outlet of the liner, no damage was observed after the test. Through our studies we have confirmed the applicability of the selected SiC^F/SiC composite as a combustor liner. In this paper, we describe the present state of the R & D of a CMC combustor liner.
