摘要：本文通过对玻璃钢受力模型分析，声发射（ＡＥ）技术以及横向纤维／韧性树脂拉伸试验的研究，结果表明，耐腐蚀玻璃钢渗漏的主要原因是：基体树脂的断裂延伸率较低，制品在承受一定载荷，并在应力腐蚀情况下，造成树脂的低应力开裂，并逐步扩展而致。制品在受力过程中产生的树脂区域应力集中，更使树脂开裂的加剧，运用声发射技术亦验证上述结果的存在。另一方面表明，对于各种树脂含量的玻璃钢结构层，基体树脂的延伸率分别要求为３～６％是必要的。
In this paper,mechanical model of FRP was analyzed. Acoustic emission(AE) technique and tensile test of latitudinal fiber for toughness matrix were studied. The results show that the major cause of permeability-seepage on corrosion resistant FRP is its lower breaking elongation rate. When loaded and stressed,the product can result in low matrix stress crack and gradually stretch. The crack was aggravated by the stress concentration of matrix region and was verified by the AE technique. The authors consider it necessary that the matrix elongation rate be among 3-6% in the laminated structure of FRP.
