ABSTRACT:
A double shear lap join is formed between metal and composite structure by welding Z-pins in the composite in the joint area to the metal tangs on the metal structure. The joint has modest strength but is less susceptible to shock damage than an adhesive bond or to notch effect crack propagation damage associated with fastened metal/composite joints.
