Abstract

Abstract

High-Performance CFRP tendon is a nonmetal fiber polymer reinforcement,which has the characteristic of high strength,lightweight,corrosion resistance,etc. So it is one of the best choices,in which CFRP tendons are substitute for the ordinary and prestressing reinforcements in the corrosion circumstances and meeting the using requirements of the special structures. A meliorative test method of the compression performance of the CFRP tendons is put forward in this paper. The compression performance of the domestic and imported CFRP tendons is tested by the meliorative test method,and the influence of the seawater corrosion on the CFRP tendons is studied. The results show that the CFRP tendons have the performance of the high strength and the large ultimate strain of compression, and the stress strain curve expresses as approximate lines. The influence of the artificial seawater corrosion on the tension performance of CFRP tendons is very little,but it is obvious on the compression performance.
