CMCs offer measurable advantages in specific strength and stiffness, but have yet to overcome their relatively low fracture toughness. However, new understanding about composite damage mechanisms and the potential design benefits of stress redistribution are, again, igniting the potential use of CFCCs in structural applications. Engineers simply need to develop the necessary design framework, including an understanding of damage and a new approach to estimating residual life in order to confidently develop applications for CFCCs. This note shows that oxidation resistant high temperature, damage‐tolerant CFCCs are currently available.
