摘要

以碳纤维复合材料（Carbon Fiber Reinforced Plastics, CFRP）的超声背散射信号为研究对象，创新性地提出运用递归定量分析（Recursive Quantitative Analysis,RQA）方法获得其信号特征，实现对材料局部孔隙缺陷的识别及评估。首先，对含有孔隙率为0.2%～5.92%的标准试块的超声背散射信号分别进行递归图分析和递归定量分析。结果表明，不同孔隙率试块所对应的递归图特征表现出明显差异，同时，RQA的特征量参数——递归率与递归熵均随孔隙率的增大而增大。然后，运用RQA方法对某未知孔隙率试块进行局部孔隙缺陷评估，基于上述结论，识别得到该试块中最有可能含有局部孔隙缺陷的区域。最后，剖开该未知孔隙率试块作微观形貌观察实验，实验发现该试块实际孔隙缺陷区域与RQA识别得到的结果相同，从而验证了递归定量分析方法用于CFRP局部孔隙缺陷识别的有效性。

Abstract

Taking ultrasonic backscattering signal of carbon fiber reinforced plastics (CFRP) as the study object, a new method called the recursive quantitative analysis (RQA) was proposed to analyze this signal’s features, and then realize CFRP local pore defect identification and evaluation.Firstly, recursive plot analysis (RPA) and RQA were performed for ultrasonic backscattering signals of 5 standard CFRP specimens with the porosity of 0.2%-5.94%, respectively.The results showed that feature parameters of RQA including recursive rate and recursive entropy increase with increase in porosity.Then, RQA was performed for another CFRP specimen with unknown porosity to evaluate local pore defects, and identify regions most probably containing local pore defects.Finally, a destructive test was performed for the unknown porosity specimen to do microscopic morphology observation.It was shown that the actual pore defect regions agree well with the results identified using RQA to verify the effectiveness of RQA for identifying CFRP local pore defects.
