摘　　要：针对反复出现的小能量挤压是否会对复合材料层合板造成结构损伤,进行了碳纤维构件挤压渐进试验。应用红外无损检测方法采集对象图像,观测损伤结果,采用MATLAB图像分析软件对红外热像图进行数字图像分析。研究结果表明,碳纤维层合板试件在单次小能量挤压作用下,未出现明显缺陷;在小能量挤压重复作用下,会产生结构的损伤缺陷。采用红外热成像检测方法,可以快速、有效、可靠地检测结构损伤。In order to study that the recurrent small energy squeeze whether will cause structural damage to the compos-ite laminated plate, the carbon fiber components squeezing gradual test is done. Through object image for the collection ofnondestructive testing methods, the infrared thermal image analysis software based on MATLAB figure for digital image isused to analyze the results. The research results show that under the action of a single small energy extrusion, carbon fiberlamina specimens do not have the obvious flaw, and in small energy extrusion under the action of repeated, it can producethe structure of the defect. Through the infrared thermal imaging detection method, the structural damage can be detected inthe quick, effective and reliable state.
