dc.description.abstractIn order to increase the durability database and have a better understanding of the degradation mechanism, the effect of freeze-thaw cycling on the mode I fracture energy release rate of CFRP (Carbon Fiber Reinforced Polymer)/steel interface is studied by using wedge driving test method. Previous studies show that moisture plays an important role in freezing-thawing cycling, therefore the relationship between moisture and mode I fracture energy release rate of CFRP/steel interface is studied. Because the interfacial moisture content cannot be measured directly, a finite element simulation is established to predict the moisture distribution of the interface based on water uptake tests of component materials. The results show that the mode I fracture energy release rate of CFRP/steel interface decreases nonlinearly with apparent relative humidity. The change of failure mode from debonding within the CFRP layer to adhesive failure long the interface is also observed.cs
