Abstract

Abstract

Tension tests were carried out for a total of 39 basalt fiber reinforced polymer (BFRP) sheet specimens subjected to freeze-thaw cycles and freeze-thaw cycles-sodium chloride solution. The law of BFRP composites performance deterioration ,the effects of different environmental conditions and exposure time on durability of BFRP composites were studied. The experimental results indicate that tensile strength and elongation decrease and elastic modulus increases when subjected to the two test environments. Single environment shows more effect on BFRP tensile strength than compound environment. Compound environment shows more effect on BFRP elongation and elastic modulus than single environment. The result indicate that compound environment is more easier to cause material embrittlement than single environment. At last,a grey forecast model of BFRP relative tensile strength under environmental effect is presented.
