Typical mechanical properties of the Graphonyx composites are shown below. A compression test setup and the compression stress-strain curve are shown.
Graphonyx/epoxy 3.4 wt % nanocomposite testing.
The mechanical properties of the polymer improve a small amount by addition of 3.4 wt % of Graphonyx as shown in Table 1. Dispersion of up to 10 wt % of Graphonyx in epoxy has been done. Impact of wt. reduction not determined at this time. Studies of the mechanical properties of this material are continuing.
