Ceramic matrix composites (CMC) is promising material for high-temperature structural use in aerospace industries. Manufacturing time and cost reducation is an important issue to accelerate applying CMC into real parts. In this study, a novel manufacturing technique is developed to reduce the matrix formation process which has been one of the largest causes of long manufacturing duration. Employing the solid infiltration process, which is developed to substitute the large part of conventional liquid infiltration process, the matrix formation process time was reduced for 58%. Mechanical properties of the CMC by the new processes showed equivalent values with those of conventional CMC.
