| 摘 要： | 通过向石墨材料中掺杂氧化锆，制备ZrC／C复合材料。较系统地研究了Zr的加入量对材料性能的影响。结果表明：随着掺Zr量的增加，力学性能不断提高，在掺Zr量为10％时，材料的弯曲强度达最大值，而在掺Zr量为7．5％时，热导率达到最高；进一步研究表明，微观结构影响着材料的力学、热导率等宏观性质。

| Abstract: | Zr/C composites were prepared by means of doping ZrO 2 intographite. The effect of Zr quantity on the properties of composites was studied.It was found that the ZrC/C composites exhibited the increasing bending strength and the thermal conductivity with increasing Zr weight percent.The composite with the Zr concentration of 10% had the largest bending strength,and the thermal conductivity of the composite with 7.5%Zr was the highest. Deep investigation showed that the material microstructures affected the composite properties. |
