摘要
为了提高脉冲热像无损检测技术对复合材料缺陷的检测能力,研究了脉冲相位法用于复合材料层析检测的可能性。介绍了利用脉冲相位法对脉冲热像图进行数据处理的原理,进行了CFRP层板的脉冲相位法检测实验,并从传热学角度对实验结果进行了分析。实验证明脉冲相位法用于复合材料的层析检测是可行的。
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.
