| Summary | This standard specifies the principles, equipment, samples, test conditions, test procedures, calculations and test reports of the room temperature bending performance test method for carbon materials. This standard applies to the determination of the flexural strength and flexural modulus of three-dimensional punctured carbon-carbon composite carbon materials and quasi-three-dimensional needle-punched carbon-carbon composite carbon materials at room temperature. Carbon materials with similar structures can also be implemented by reference. |
