研究了水解老化对玻璃纤维增强聚酯复合材料拉伸试验过程中损伤机制声发射特征的影响。这些结果被用来测试的有效性Kohonen的地图建立从未老化的标本收集的AE数据。该方法能够识别和分类属于两种不同的故障模式的AE信号。Kohonen自组织地图，未老化的标本上训练，是一个有价值的工具，在评估老化标本的损伤类型。
The effects of hydrolytic ageing on the acoustic emission signature of damage mechanisms occurring during tensile tests on a glass fibre reinforced polyester composite are investigated. These results are used to test the validity of a Kohonen’s map established with AE data collected from an unaged specimen. This method enabled identification and classification of AE signals belonging to two different failure modes. The Kohonen self-organising map, trained on unaged specimens, is a valuable tool in assessment of damage type on the aged specimens.
