1 NCSX Composite Coil Testing Tests Performed During the Week of 15 March 2004

2 Tests Performed Plug Longitudinal Shear Three Point Flexure Beyond Yield

3 Plug Longitudinal Shear

4 Tested several length samples: 0.5”, 0.25”, 0.15” Tested several diameter punches: 0.187”,0.125” Various aspect ratios tested: –If the sample length is to long with respect to the punch diameter – the material crushes and ultimately the sample bursts.

5 Aspect Ratio too Large

6 Correct Aspect Ratio

7 Load – Displacement Curve

10 Three Point Flexure Beyond Yield Bare impregnated conductor samples were cycled four times below or just to yield. The samples were then cycled to nearly an inch beyond yield. Six samples were tested at room temp. Three samples were tested at LN2 temp.
