joining composite structures to metallic structures

What is it about?

As the composite materials technology advances, it increasingly replaces conventional metals. However, some parts of structures are still built using metals. In that case, how can we join the composite parts to metallic parts. The common technique has been the mechanical joints like bolted joints. This technique requires much labor and introduce holes in the structures which can reduce the load-carrying capability of the structure. As a result, this study investigated a different technique.

Why is it important?

The newly proposed technique is to construct a transition part such that one end of the part can be connected to the composite using a traditional composite fabrication technique while the other end can be welded to a metallic part. Then, one of the main questions is the strength of the transition part. This study examined the interface failure strength of the transition parts which are made of e-glass and steel fiber composite layers.
