This document specifies conditions for the determination of circumferential mechanical properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at room temperature on C-ring specimen under diametric compression. This document is specific to the tubular geometries because fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens.

This test method is straightforward to carry out and low-material consumption. It provides the C-ring modulus, the mechanical response and the ultimate fracture force. If the ultimate fracture occurs within the linear elastic domain, then the tensile strength can be determined from the corresponding ultimate fracture force. The information can be used for material development, control of manufacturing (quality insurance), material comparison, characterization, reliability and design data generation for tubular components.

This document addresses, but is not restricted to, various suggested test piece fabrication methods. This document is primarily applicable to ceramic matrix composites tube with a continuous fibrous-reinforcement: unidirectional (1D, filament winding and tape lay-up), bidirectional (2D, braid and weave) and multi-directional (xD, with x >2).
