摘　　要：纤维复合材料在使用过程中可能会出现各种缺陷,如裂纹、分层、脱粘等。这些缺陷会导致材料的性能下降,甚至引发失效。为预测和评估纤维复合材料的长期使用性能,本文开展了基于声学参数的纤维复合材料机械强度无损检测技术研究,通过数值模拟和超声实验研究,建立了基于超声无损检测技术的纤维复合材料检测信息特征提取和性能评价方法,开发了纤维复合材料的超声检测装置。实验结果表明在玻璃纤维复合管刚度矩阵测量精度验证最大误差1.15%,在钢管上对检测装置验证得出杨氏模量精度最大误差9.3%,泊松比精度最大误差-8.27%。Fiber composite materials may have various defects in the process of use,such as cracks,delamination,debonding and so on.These defects can lead to the deterioration of the performance of the material and even cause failure.In order to predict and evaluate the long-term service performance of fiber composite materials,this paper carried out research on the nondestructive testing technology of mechanical strength of fiber composite materials based on acoustic parameters.Through numerical simulation and ultrasonic experimental research,a method for the detection information feature extraction and performance evaluation of fiber composite materials based on ultrasonic nondestructive testing technology was established,and an ultrasonic testing device for fiber composite materials was developed.The experimental results showed that the maximum accuracy verification error of stiffness matrix of glass fiber composite pipe was 1.15%,the maximum accuracy error of Young's modulus was 9.3%,and the maximum accuracy error of Poisson's ratio was-8.27%.
