Analysis of temperature distribution during tension test of glass fiber reinforced plastic by fiber orientation variation.
In this paper, analysis of temperature distribution by fiber orientation variation under tension test was proposed through IR thermography camera. Lock-in method, which is one of technique in IR thermography camera to measure minute change in temperature, was utilized to monitor temperature distribution and change during crack propagation. Method to analyze of temperature distribution by fiber orientation variation under tension test of GFRP via IR thermography camera was suggested. At the maximum stress point, temperature was significantly increased. As shown previously, specimen with shorter fracture time showed abrupt increment of temperature at the maximum stress point. Specimen with longer fracture time displayed increment of temperature after the maximum stress point.
