Abstract
A novel joint for connecting a closed composite adherend utilizes complementary scarf surfaces on the adherends and then bonds the adherends together. The angle of the scarf is determined by the materials used and the expected loads. Preferably, constant stiffness is achieved through the joint. In alternative embodiments, lap joint areas are included to create localized stress free zones. A method of creating the scarf surfaces utilizes a wrapping technique in which the edges of a lamina of composite material are prepared so as to provide a desired edge termination which permits each layer to be bonded to the adjacent adherend.
