Abstract

Abstract

In order to study the durability of BFRP sheets under the conditions of ultraviolet light,ageing tests were done for a total of 70 BFRP sheets specimens impregnated by two different resins under the conditions of protection and without protection. The preliminary test results after 6464 h indicate that for BFRP1 under the conditions without protection,the tensile strength is decreased by 11.03% ,the extensibility is declined by 14.75% ,and Young's modulus is dropped by 5.23% ;while for BFRP2,the tensile strength is decreased by 2. 02% ,extensibility is declined by 13.73% ,and Young's modulus is increased by 0.34% ;under the conditions with protection,the tensile strength,extensibility and Young's modulus of BFRP1 is respectively dropped by 8.01% ,16.57% and 1.38% ; while the tensile strength,extensibility,and Young's modulus of BFRP2 are respectively dropped by 1.51% ,9.59% and 5.60%. Therefore,BFRP sheets have good durability under the ultraviolet light,protection has a protective effect on the properties of BFRP sheets.
