本文件规定了炭素材料室温弯曲性能试验方法的原理、设备、试样、试验条件、试验步骤、计算和试验报告。
本文件适用于室温下测定三维穿刺炭-炭复合炭素材料和准三维针刺炭-炭复合炭素材料的弯曲强度和弯曲模量。类似结构的炭素材料也可参照执行。

Scope

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.
