GB/T 46063-2025 "Continuous Fibre-Reinforced Ceramic Matrix Composites—Test Method for Room Temperature Hoop Tensile Properties of Tubes" is a national standard for determining the hoop (i.e., circumferential) mechanical properties of fibre-reinforced ceramic matrix composite tubes. This standard specifies in detail how to apply uniform hydraulic pressure inside a tubular specimen to generate hoop tensile stress, thereby measuring key performance parameters such as hoop tensile strength, elastic modulus, and fracture strain. To ensure the standardization of the tests, the standard sets clear requirements for testing equipment, primarily covering the hydraulic system used for pressurization, precise pressure sensors, high-precision strain gauges or extensometers for measuring circumferential strain, and corresponding data acquisition and analysis systems. This standard provides a unified methodological basis for evaluating the performance and quality control of unidirectional, bidirectional, or multidirectional fibre-reinforced ceramic or glass matrix composite tubes.
