摘要

The thermal expansion law of matrix-modified C/C composites under high temperatures is studied. The results show that the law between the temperature and the thermal expansion coefficient of C/C composite, accords with the general linearity which exists in carbon materials under 900°C. However, the law between the temperature and the thermal expansion coefficient of matrix-modified C/C composite meets exponential relation from 900°C to 1500°C. The laws are reliable and reasonable as indicated by our experiments and mathematical analysis. Therefore, it is significant for improving the matching degree of the thermal expansion coefficient between C/C composites and their oxidation resistant coatings, and for raising the ability to resist oxidation under high temperatures.
