Research Institute of Advanced Materials Gas-Generator (AMG), which is a joint effort by the Japan Key Technology Center and 14 companies in-Japan, has, since 1993, been conducting technological studies on an innovative gas generator that will use 20% less fuel, weigh 50% less, and emit 70% less NOx than the conventional gas generator through the use of advanced materials[1]. In the course of R&D, the feasibility of applying the gradient composite material with ceramic matrix composite (CMC) and glass matrix composite (GMC) which is expected to reduce the thermal stress of actual parts with temperature distribution was evaluated based on its mechanical and thermal properties, productivity and stress analysis for an actual part as a combustor liner with 500 mm in diameter, and non-cooled combustion tests in the condition of 1873 K as the liner outlet temperature. Through our studies we have confirmed the applicability of the selected CMC/GMC hybrid composite as a combustor liner.
