Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.
Thermal contact resistance plays a very important role in
heat transfer efficiency and thermomechanical coupling
response between two materials, and a common method to
reduce the thermal contact resistance is to fill a soft interface
material between these two materials. 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 resistance
