摘要

无黏剂C/C复合材料同其他C/C复合材料一样存在抗氧化性能差这一致命的弱点

采用防氧化表面涂层不能很好地解决涂层与基体间热膨胀差异所带来的裂纹问题 .通过采用一定比例的生石油焦、B4C和SiC混合磨粉后

加入短碳纤维

无需添加黏结剂模压成型

而后烧结制得结构密实均匀的碳 /陶复合材料 .在 900～1200℃温度范围内对其抗氧化性能进行测试

结果表明该材料具有良好的抗氧化性能。从热力学的角度对其抗氧化机理进行了探讨 .

Abstract

In-situ carbonization of pre-oxidized fibre mixed with green petroleum coke powders without any binder to prepare C/C composites is an effective method to manufacture advanced C/C composites in a shorter period and with lower cost.But just like other C/C composites

the oxidation resistance of the material produced by this kind of technology is not satisfying even with oxidation resistant coating because of the different thermal expansion coefficients between the coating and the matrix.

and the crack problem will occur.A mixture of green petroleum coke

B 4C and SiC together with short carbon fiber is used as starting materials.The mixture is then press-formed without binding agent after grinding

dense and homogeneous bindless Carbon/Ceramic composites are then obtained after sintering.Composites thus prepared have excellent anti-oxidation property between 900-1000℃.Anti-oxidation mechanism is also discussed from the viewpoint of thermodynamics.
