摘要

复合绝缘子FRP棒脆性断裂问题在国内引起了广泛关注。在实验室中，采用两种加载方法模拟了脆性断裂过程。一种是恒拉荷载法，用于测试FRP芯材的抗应力腐蚀性能。另一种是减小拉伸载荷法，目的是模拟使用中脆性断裂断面的相似形态。对影响脆性断裂过程的一些重要因素进行了讨论和澄清，这些因素在IEC草案中没有很好地描述。最后，分析了脆性断裂过程的声发射特征。它与正常的短期拉伸破坏过程有很大的区别。

Research on the brittle fracture of FRP rods and its acoustic emission detection

Brittle fracture of composite insulator FRP rods has aroused widespread attention in China. In the laboratory, two load-applying methods are used to simulate the brittle fracture process. One is constant tensile load method, which is used to test the resistance of FRP core against stress corrosion. The other is decreasing tensile load method, with the purpose to simulate similar appearance of brittle fracture section in service. Some important factors that influence the brittle fracture process, which are not well described in IEC Drafts are discussed and clarified. Finally, the acoustic emission (AE) feature of the brittle fracture process is analyzed. It is in great difference from normal short-term tensile failure process.
