Abstract

The methodology of joint application of acoustic emission diagnostics (AED), vibration-based diagnostics (VBD), and videotaping for monitoring the load-bearing capacity of polymer composite material (PCM) specimens during compression tests is considered. Test specimens cut from a composite panel were divided into five groups of two specimens each. Before the compression test, the specimens of the second group were subjected to an impact with an energy of 50 J, the third group, with 70 J, the fourth group, with 90 J, and the fifth group, with 110 J. Assessment of the state of damage of the specimens during compression was carried out using AED, VBD, and video recording. The obtained results confirmed the high efficiency of the complex application of these methods. Their joint application allowed us not only to monitor the level of bearing capacity of the specimens in the loading mode, but also to trace the sequence of mechanisms of evolution of multilayer carbon fiber-reinforced plastic fracture in compression at the stage of ultimate deformation of the material.

声发射和振动诊断方法在复合材料试样压缩试验中的应用

考虑了声发射诊断（AED）、振动诊断（VBD）和录像联合应用的方法，以监测压缩试验过程中聚合物复合材料（PCM）试样的承载能力。从复合板上剪下的试件分为五组，每组2个试件。压缩试验前，第二组试件分别受到50 J、70 J、90 J、110 J的冲击，采用AED、VBD、录像等方法对压缩过程中试件的损伤状态进行评估。所得结果证实了这些方法在复杂应用中的高效率。它们的联合应用使我们不仅可以监测试件在加载模式下的承载水平，而且可以追踪材料在极限变形阶段多层碳纤维增强塑料压缩断裂的演化机制序列。

期刊介绍： Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
