Abstract
The effect of the volume fraction of resin (Vr) on the bonding strength of Al/epoxy resin joints via interpenetrating phase layer (IPL) was investigated. The tensile strength reached maximum to be 38.3 MPa when Vr was 85%. Fracture occurred at either epoxy resin/IPL interface or Al/IPL interface depending on Vr (Vr≦85%; epoxy resin/IPL interface, Vr≧85%; Al/IPL interface). Fractography revealed that the separation and the fracture of the epoxy resin occurred on the epoxy resin/IPL interface, and the separation and the fracture of Al occurred on the Al/IPL interface. These results can be explained by the strength of each interface estimated from rule of mixture. The effect of grading Vr on the bonding strength was also investigated. The tensile strength of joint with the functionally graded IPL structure was higher than that of joints with the homogenous IPL structures.
