Research on temperature field of CFRP electric-thermal damage

Abstract

Abstract:

In order to study the temperature field distribution of the Carbon Fiber Reinforced Polymer(CFRP)material, the relation of temperature and direct current have been investigated on electric-thermal damage detection system. ABAQUS software is used to simulate the direct electrification process of CFRP based on current heating theory,and the temperature field distribution contour plot and temperature changes curves of characteristic points under different currents are obtained. By contrast of the experimental and stimulant results, fine consistency is reached.Surface temperature increase linearly with the current increase from 4A to 6A and 8A and reach stabilization after 160 s while the temperature is 162 ℃、177 ℃and 195 ℃ respectively. It shows that the detection system and simulation models could correctly predict the temperature field of current heating disposing and provide theory evidence for selecting current heating disposing parameters reasonably.

Key words: CFRP, thermal-electric damage, temperature field numerical simulation
