Abstract:

A double-sided shear test was carried out on the sintered clay brick block bonded with carbon fiber reinforced composite material （CFRP） to investigate the failure morphology and bonding properties of the CFRP-clay brick block interface under different sulfate dry-wet cycles， and the sulfate corrosion was discussed. Under the degradation mechanism of CFRP-clay brick interface bond performance， a bond strength degradation model is proposed. The results show that the failure morphology of the CFRP-clay brick block interface is greatly affected by the sulfate dry-wet cycle； the interface bonding properties （ultimate load-bearing capacity， peak shear stress） first slightly increase with the cycle time and then decrease rapidly. On this basis， according to the existing interface theory， a CFRP-clay brick block interface bond-slip model affected by the cycle time is proposed. The predicted value of the model is compared and analyzed with the experimental data. The model can accurately express the impact the law of degradation of interfacial bonding properties caused by sulphate dry-wet cycles.

Key words: sulfate, carbon fibre reinforced plastics, clay brick, interface, bonding-slip relationship
