摘要

The current research work aimed to measure the effect of graphene nanoparticles reinforcement on thermal and mechanical behaviour of glass fibre/epoxy composites. Epoxy and hardener were mixed in a 10:1 ratio, with graphene content ranging from 0 to 10% in increments. The mixture was then cured in a medium-density fibreboard mold and processed using a laser cutting machine. A guarded hot plate thermal test rig was utilized for determining the thermal conductivity (TC) of the samples. The mechanical behaviour was studied by evaluating interlaminar shear strength, flexural strength, and ultimate tensile strength (UTS), all tested using a universal testing machine in accordance with ASTM standards. Additionally, Rockwell hardness was measured. The results indicate a notable increase in TC and mechanical strength with up to 8 wt% graphene, with TC peaking at 12.5729 W/m K and UTS reaching 412 MPa. However, at 10 wt%, a decrease in these properties was observed, likely due to graphene agglomeration barrier to material performance. Scanning Electron Microscope analysis confirmed excellent fiber/matrix bonding up to 8 wt%, with reduced performance at higher graphene concentrations due to agglomeration.
