A testing system of high temperature thermal contact resistance based on INSTRON 8874 is established in the present paper, which can achieve 600 Celsius degree at the interface. Based on this system, the thermal contact resistance between superalloy GH600 material and three-dimensional braid C/C composite material are experimentally investigated, under different interface pressures, interface roughness and temperatures, respectively. At the same time, the mechanism of reducing the thermal contact resistance with carbon fiber sheet as interface material is experimentally investigated. Results show that the present testing system is feasible in the experimental research of high temperature thermal contact resistance5 pagesPDF© 2014 University of Pretoria. All rights reserved.
