摘要

摘要: 对2种不同树脂浸渍玄武岩纤维布的90个试件，分别在3.5倍浓度和5倍浓度的人工海水干湿交变环境下进行老化试验。结果表明：第1种玄武岩纤维布在3.5倍浓度海水中老化330d，拉伸强度和伸长率分别下降8.36%和28.74%，弹性模量提高了1.68%；在5倍浓度海水中老化330d，拉伸强度和伸长率分别下降12.77%和26.30%，弹性模量提高了3.24%；第2种玄武岩纤维布在3.5倍浓度海水中老化330d，拉伸强度和伸长率分别下降9.50%和18.44%，弹性模量提高0.43%，在5倍浓度海水中老化330d，拉伸强度、伸长率和弹性模量分别下降8.53%，20.88%，0.43%。结果表明：玄武岩纤维布具有较好的抗海水腐蚀性能。最后，与碳纤维增强复合材料(CFRP)、芳纶增强复合材料(AFRP)，玻璃纤维增强复合材料(GFRP)等其他纤维片材进行了老化性能的对比，发现BFRP具有较好的抗老化性能。

Abstract: In order to investigate the law of properties' change for BFRP sheet under the condition of wet-dry cycling seawater,ageing tests were done for a total of 90 specimens impregnated by two different resins under the conditions of 3.5 times and 5 times concentration of artificial wet-dry cycling seawater. The results show that BFRP1 in 3.5times concentration seawater for 330 d,the tensile strength and extensibility are respectively dropped by 8.36% and 28.74% ,and the Young's modulus is increased by 1.68% ; BFRP1 in 5 times concentration seawater for 330 d,the tensile strength and extensibility are respectively dropped by 12.77% and 26.304% ,and the Young's modulus is increased by 3.24% ; BFRP2 in 3.5 times concentration seawater for 330 d,the tensile strength and extensibility are respectively dropped by 9.50% and 18.44% ,and the Young's modulus is increased by 0.43% ,BFRP2 in 5 times concentration seawater for 330 d,the tensile strength ,extensibility and the Young's modulus are respectively dropped by 8.53% ,20. 88% and 0.43% . Therefore,BFRP sheet has good resistance to seawater corrosion . Finally,contrast with other fiber sheets' aging experiment like CFRP,AFRP,GFRP and so on,it is shown that the basaltreinforced composite material has good resistance to seawater corrosion.
