摘　　要：共固化成型的蜂窝夹层结构容易产生底角发泡胶缺失类缺陷,采用带定制楔块的超声聚焦探头对带有人工缺陷的试块进行检测。检测结果表明缺陷的特征信号明显,可利用该方法对此类缺陷进行准确识别。The defects of the missing styrofoam often occur in the co-cured honeycomb sandwich structure. In the experiment, an ultrasonic focusing probe with a customized wedge was used to detect the reference block with artificial defects. The results show that the ultrasonic wave signal of the defects was obvious, and such defects could be accurately identified by the mehtod.
