The hot curing Araldite LY 564 (Bisphenol-A resin), Aradur 2954 (cycloaliphatic polyamine hardener) epoxy matrix system was sourced from Huntsman Advanced Materials. The GNP epoxy nanocomposites were manufactured at five weight loading specifications, 1, 2.5, 5, 7.5 and 10 wt.% with respect to the overall mass of the nanocomposite. The GNPs were dispersed in the resin using a Synergy Speedmixer DAC 4000 under 5 mbar vacuum at 800 rpm for 2.5 minutes. The mixture was degassed for 10 minutes at 40 °C. The hardener was subsequently added (100:35 resin, hardener mass ratio) and mixed under 5 mbar vacuum at 800 rpm for 3 minutes, then 2350 rpm for 2 minutes. The mixture was degassed for 25 minutes at 40 °C and poured into a silicone mould, itself manufactured using CS25 condensation cure silicone rubber from Easy Composites, and 3D printed shape cut outs. The mixture was further degassed at 40 °C until bubble free. A manufacturer recommended cycle of 1 hour at 80 °C and 4 hours at 160 °C was used to cure the nanocomposites.
