Carbon Fiber Reinforced Ceramic Composites for Propulsion Applications

摘要

This report presents a critical review of the processing techniques for fabricating continuous fiber-reinforced ceramic matrix composites (CMCs) for possible applications at elevated temperatures. Some of the issues affecting durability of the composite materials such as fiber coatings and cracking of the matrix because of shrinkage in polymer infiltration and pyrolysis (PIP)-process are also examined. An assessment of the potential inexpensive processes is also provided. Finally three potential routes of manufacturing C/SiC composites using a technology that NC A&T developed for carbodcarbon composites are outlined. Challenges that will be encountered are also listed.
