Scope

This document specifies the principles, instrumentation and materials, specimens, test conditions, test procedures, result calculation, and test reports for determining the S-N fatigue life curves and conditional fatigue limit of carbon fiber reinforced ceramic matrix composites under high-temperature conditions.
This document is applicable to determining the S-N curves and fatigue limits of continuous carbon fiber reinforced ceramic matrix composites under high-temperature environments of 600°C to 1650°C. Continuous silicon carbide fiber reinforced ceramic matrix composites can be used as a reference for this purpose.
