Scope

This document specifies the principles, equipment, samples, test conditions, test procedures, calculations, and test reports for the bending performance test of carbon materials at room temperature. This document is applicable to the determination of the bending strength and bending modulus of three-dimensional puncture 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 in accordance with this document.
