Purpose and goal
We propose a composed weld material with significantly better mechanical properties than the surrounding metal sheets as a new approach to lightweight structure design. The project will test if long Carbon nanotube yarns can retain their structure and extremely high strength when incorporated into laser welds. Analysis of the weld will reveal how the yarn is geometrically, structurally and chemically embedded and subsequently whether it behaves advantageous under mechanical testing.
