Abstract

The Interfacial shear strength (IFSS) is a key parameter to determine the service performance of a carbon fiber (CF) reinforced composite. ZnO nanowires (ZWs) grow on the CF surface is a new method to reinforce the IFSS, where ZWs grow radially on carbon fibers to form a hybrid reinforcing phase. But the properties of ZWs are significantly different with varying ZW dimensions, in turn, causes a change in IFSS hence affecting the CFRP performance. To evaluate the optimal interfacial properties of CF composites, a micro-damage model was conducted to study the adhesive properties of a single ZW pullout from the matrix with varying dimensions of ZWs. The cohesive zone approach was used to model the interface between ZWs and the matrix. The simulation results showed that adhesive properties between ZWs and epoxy increase with the increase of ZWs' diameter and length. A pullout test was also conducted to determine the interfacial shear properties of the hybrid CF composites and verify the results of numerical values.
