摘要

对采用高压釜法和真空模塑法制作的 AFM 碳纤维样品进行了静态测试。采用声学(声发射和超声波)方法、应变测量和薄片显微分析来检测缺陷。通过声发射信号在应力提升区域的位置,可以确定高压釜成型的缺陷数量比真空成型少十倍。通过超声波和声发射方法、应变测量和显微分析,可以确定 AFM 碳纤维的结构、缺陷坐标及其类型。在对真空模塑法制作的空载样品进行测试时,发现了制造缺陷,这些缺陷在静态拉伸过程中逐渐增大,并导致新的破坏。在高压釜成型法生产的样品中没有发现制造缺陷。通过对真空方法生产的样品进行显微分析,发现了与纤维破坏、基质开裂和分层有关的缺陷。对高压釜成型法制备的样品进行的测试表明,这些样品几乎没有缺陷。

Influence of Molding Methods on Defects in AFM Carbon Fiber Samples under Static Loading

Static tests of AFM carbon fiber samples made by autoclave and vacuum molding methods were carried out. Acoustic (acoustic emission and ultrasonic) methods, strain gauging, and microanalysis of thin sections were used to test for defects. The location of acoustic emission signals in the area of stress raisers made it possible to establish that the number of defects in autoclave molding is ten times less than under vacuum molding. Ultrasonic and acoustic emission methods, strain gauging, and microanalysis allowed determining the structure of AFM carbon fiber, the coordinates of defects, and their type. During the testing of unloaded samples made by vacuum molding, manufacturing defects were found that grew in size during static stretching and led to the occurrence of new destructions. No manufacturing defects were found in the samples produced by autoclave molding. Microanalysis of samples produced by the vacuum method revealed defects associated with fiber destruction, matrix cracking, and delamination. Tests of samples prepared by autoclave molding have shown that there are practically no defects in them.

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).
