This document specifies the principles, equipment, specimens, test conditions, test steps, calculations and test reports of the room temperature bending performance test method of carbon materials. This document is suitable for measuring 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 as a reference.
