摘要：

The contact strength of polyimide and graphic was experimentally investigated by considering the temperature effect. A new contact area measurement method based on photogrammetry was developed for high temperature testing. The results show that the temperature has apparent influence on the contact strength of polyimide material, but almost no influence on that of graphite material. The mechanical behavior of the two materials are also investigated under different temperatures, and it can be found that there existing a positive correlation between the influence of temperature on contact strength and the influence of temperature on mechanical behaviour.
