考察了B4C／C复合材料在800℃、2L／min干燥空气流量的氧化环境下其性能参数如重量、体积、密度、电阻率、抗压强度的变化情况。并从材料表层结构的变化解释了这些参数的变化规律。
The change of performance parameters such as weight, volume, density, resistivity and compressive strength of B4C / C composites at 800 ℃ and 2L / min dry air flow were investigated. The changes of these parameters are explained by the changes of the surface structure of materials.
