| Abstract: | To increase the detection capability of pulsed thermography for defect inspection of composite materials,the feasibility of thermal tomography of composite materials using PPT(pulsed phase infrared thermography) was studied here.The principle of PPT for processing pulsed thermographic data was described.A PPT experiment was made on a CFRP(carbon fibre reinforced plastics) sample,and the results analysis was made.The results of the experiment gave it evidence that thermal tomography of CFRP using PPT was feasible. |
