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.
