Abstract
Apparatus and methods provide for a non-linear scarf joint and a method for joining two components utilizing a non-linear scarf joint. A non-linear scarf joint includes multi-planar surfaces on connection ends of two components being joined to create a structure. Each multi-planar surface includes a first faying surface, a second faying surface, and a transition faying surface joining the first and second faying surfaces. A transition scarf angle associated with the transition faying surface is different than scarf angles associated with the first and second faying surfaces.
