STUDY ON THE EFFECT OF ADHESIVE PROPERTIES ON CRACKED STEEL PLATES REINFORCED BY CFRP

Abstract

Abstract: Steel structure with crack used in marine engineering is the object of study. Tensile properties of steel plates reinforced by CFRP is simulated by the model established with virtual fracture closure method. The influence of shear strength and elongation of the adhesive on the reinforcement was analyzed and compared. The effect of marine environment factors such as alternating hot and humid, salt mist and strong solar radiation is studied by model test. The reinforcement program is optimized through using marine-resistant adhesive. The results show that the properties of adhesive has little effect on the yield point of reinforcement structure, but it can influence the ultimate capacity obviously. The performance of adhesive can be decreased by environment factors. Reliability and durability of reinforcement can be improved by using marine-resistant and excellent adhesive.

Key words: composite reinforcement, crack, adhesive, environment test, tensile properties
