摘要

利用循环加热和傅立叶变换获得的相位图像对碳纤维增强塑料(CFRP)试样进行了主动热成像无损检测，并将该方法的缺陷检测能力与传统的闪速加热热成像方法进行了比较。实验结果表明，当相位图像的频率与循环加热频率相等时，缺陷检测能力显著提高。与闪速加热相比，循环加热获得的相位图像信噪比更高，但加热过程中被测物体的温升低于闪速加热。这些结果表明，所提出的检测方法对cfrp和其他树脂基材料是有效的。

Active thermography inspection of CFRP using cyclic heating and Fourier transform—comparison with flash heating method

Active thermography nondestructive inspection using cyclic heating and phase images obtained via the Fourier transform is performed for carbon fiber-reinforced plastic (CFRP) specimens, and the defect detection capability of this method is compared with that of the conventional thermography method using flash heating. The experimental results indicate that the defect detection capability is significantly improved when the frequency of the phase image is equal to the cyclic heating frequency. Compared with the flash heating method, a higher signal-to-noise ratio is observed in the phase images obtained via the cyclic heating method, although the temperature increase of the inspection object during heating is lower than that observed during flash heating. These results suggest that the proposed inspection method is effective for CFRPs and other resin-based materials.
