This standard specifies the test method for the tensile properties of carbon/carbon composites (primarily targeting three-dimensional piercing and quasi-three-dimensional needle-punched structures) at room temperature. Its core purpose is to unify the measurement and calculation of key mechanical parameters such as tensile strength, tensile elastic modulus, and Poisson's ratio. The standard clearly defines requirements for the testing environment, specimen preparation, critical loading rate control (e.g., 0.5-1.0 mm/min), and equipment such as universal material testing machines (or composite tensile testing machines), providing a unified technical basis for quality evaluation of such high-performance materials in fields like aerospace.
