A Simulation Study for the Influence of Pulse Heating on Thermal Imaging of Carbon Fiber Composites

Abstract:

Article Preview

Transient temperature-fields of carbon fiber composites which contained defects were numerically simulated. When the total heat was constant, the influences of different pulse heating methods on thermal imaging temperature difference and contrast of carbon fiber composites surface were analyzed. The peak values of temperature difference and contrast declined progressively with the progressive decrease of heat flux, and all the peak values postponed. With the increase of initial heat and the decrease of second heat, the peak values of temperature difference and contrast increased progressively at the first emergence, and declined progressively at the second emergence. With the progressive increase of interval, the extreme values of temperature difference and contrast were almost invariant at the first emergence, and declined by degree at the second emergence.
