Abstract This paper presents an experimental investigation on the degradation of carbon/glass/basalt fiber reinforced polymer (i.e., CFRP/BFRP/GFRP) exposed to simulated seawater sea sand concrete environments (SWSSC) at 25, 40 and 60 °C for 6 months. The presence of NaCl in simulated concrete environment was found beneficial for the moisture uptake of CFRP and GFRP. The greater fiber degradation of BFRP was attributed to its high aluminium, iron and magnesium contents on fibers. Further, FRPs showed greater degradation resistance in high performance concrete solutions that have a lower alkaline content. Thus, CFRP exhibited the best durability to simulated SWSSC environments, followed by GFRP and BFRP.

纤维增强聚合物 (FRP) 在模拟海水海砂混凝土 (SWSC) 环境中的耐久性

摘要 本文介绍了碳/玻璃/玄武岩纤维增强聚合物（即 CFRP/BFRP/GFRP）在 25、40 和 60 °C 的模拟海水海砂混凝土环境 (SWSC) 中降解 6 个月的实验研究。 . 发现模拟混凝土环境中 NaCl 的存在有利于 CFRP 和 GFRP 的水分吸收。BFRP 更大的纤维降解归因于其在纤维上的高铝、铁和镁含量。此外，FRP 在碱性含量较低的高性能混凝土溶液中表现出更高的抗降解性。因此，CFRP 对模拟 SWSSC 环境表现出最好的耐久性，其次是 GFRP 和 BFRP。
