This study highlights the improvement in the thermal properties of CFRP composites modified with lower concentrations of graphene reinforcement (ADG-NH2/epoxy/CFRP). Thermal properties such as storage modulus, loss modulus, damping factor and glass transition temperature of the composites were investigated through dynamic mechanical analysis with a temperature scan range of 30 to 200 °C and thermogravimetric analysis measurements. Five symmetrical CFRP composite laminates were prepared through a hand layup process assisted by vacuum bagging technique using various wt. % proportions (0.25, 0.5, 0.75 and 1) of ADG-NH2/epoxy along with a neat epoxy. A slight increase of ~ 2 % in the glass transition temperature Tg was observed for the modified composites. It was observed that the ADG-NH2 composites showed ~54 % increment in storage modulus E', ~ 41 % increase in loss modulus E'' compared to neat epoxy CFRP laminate composites. Thermal stability values were determined through integral procedural decomposition temperature measurement and an enhancement from 389.1 to 411.9 °C was observed. Morphological properties of fracture surfaces were characterized by SEM micrographs and XRD analysis.
