Evaluation of Continuous Fiber-Reinforced Ceramic Composites Fabricated using High Pressure Resin Transfer Molding

Abstract

The development of continuous fiber-reinforced ceramic composites improves the fracture toughness of ceramic materials. A challenge in developing continuous fiber ceramic composites is the manufacturing process. Chemical vapor infiltration (CVI) can be used to make ceramic composites, but the process is expensive. Polymer infiltration and pyrolysis (PIP) is a lower cost manufacturing method but requires long infiltration cycles to improve the part quality. High pressure injection improves upon the time required by traditional PIP while remaining cheaper than CVI. In this study, preceramic polymer precursor is used as the matrix material with silicon carbide fiber-reinforcement. The matrix density can be improved by using high pressure injection which forces preceramic polymer precursor into ceramic composites, leading to improved parts. This study focuses on the material properties of pressure injection manufactured silicon carbide ceramic composites (SiCf/SiC) and compares to reported properties of traditional manufacturing methods. Flexure tests and density measurements are performed. The results show high pressure injection improves composite modulus and part density over PIP parts.
