Test results show that the resistance to stress 大提高的芯棒。近年来，国内外大多数芯棒厂家都 corrosion cracking (SCC) of different types of boron-free rod 采用 ECR 纤维生产芯棒，并推荐了关于复合绝缘 passing through the stress corrosion testing criteria varies greatly. For boron-free FRP rod with best resistance to SCC, it 子用芯棒耐应力腐蚀性能的试验方法[13- 14] 。这种芯 is hard to be brittle-fractured even in severe circumstance. To 棒逐渐得到了用户的认可，普遍称这种提高了耐应 suit for the different requirement of engineering application, 力腐蚀性能的芯棒为耐酸芯棒。 based on the test results the authors present an impro
