Both the glass and carbon fibre fabrics were cut into dimensions of 300 mm × 250 mm. The pad-drycure coating technique (as shown in Fig. ) was employed to coat the glass and carbon fibre fabrics with GNP dispersion. A laboratory-scale padder machine (Roaches, UK) was used to coat the glass and carbon fabrics with the GNP dispersion, followed by drying at 100°C for 7 minutes in a Mini-Thermo (Roaches, UK). The GNP ink was placed between the two rubber rollers of the padder, and the padding roller pressure and speed were adjusted to 0.5 bar and 1 m/min, respectively. Two coating cycles were carried out, with each cycle including one padding and one drying pass.
