This standard is applicable to the ablation experiments of ablative materials such as heat prevention, insulation, coating materials, general ceramic materials, high-temperature ceramic materials, carbon/carbon composite materials, and refractory metals. The oxygen acetylene ablation test method is applicable to the ablation experiments of heat prevention, insulation, coating materials, and general ceramic materials; The plasma ablation method is applicable to the ablation tests of ablative materials such as carbon/carbon composites, refractory metals, and high-temperature ceramic materials. The ablation test of other materials can be used as a reference. Test content
Burn the oxygen acetylene flame or plasma jet vertically onto the sample, ablate or burn through the material, measure the back temperature and ablation time during the ablation process of the sample, measure the thickness and mass changes of the sample before and after the test, and calculate the linear ablation rate, mass ablation rate, and adiabatic index of the sample Testing Standard Product Name Testing Item Testing Standard Ablative Material Ablative Material Ablative Test Method GJB 323A-152 0173 3840 Ablative Material Ablative Test Method GJB 323B-2018 Function of testing report:1.
