摘要：

Interference fit micropinning is a novel joining method that involves inserting thin pins with a size interference into an array of ultra-thin holes to create high strength structural joints. An experimental and finite element (FE) modelling study demonstrates the high structural properties of composite-to-metal joints using interference fit micropins. The joint studied consisted of plates of carbon-epoxy laminate and aluminium alloy joined using an array of steel micropins (505 mu m diameter) with a close interference (1%) to the holes. The interference fit micropins are effective at creating composite-to-metal joints with high specific ultimate strength and ductility. The capacity of micropins to provide composite-to-metal joints with high structural properties under lap shear and peel load conditions is demonstrated. The effect of the spacing and number of micropins on the joint properties is evaluated.
