摘要：The material used for the study is bi-axial glass cloth with epoxy resin. Two sets of laminates were manufactured using vacuum assisted resin transfer moulding, one laminate with parent material (P1, P2) and the other laminate with graphene platelet nanopowder (P1-GPN, P2-GPN). For the graphene platelet nanopowder samples, addition of 0.1% weight of graphene platelet nanopowder is mixed with epoxy resin. Three different tests such as tensile, compression and impact were conducted on the composite material. There was an increase of 11.18% and 33.4% in tensile strength, 26.4% and 24.6% in compression strength when compared to the parent samples of 2 and 3 mm thickness, respectively. This strength was obtained with the reduction of fibre content when compared to other research works. Also high-velocity impact test using gas-gun method was performed on parent and blended samples. The energy absorption levels of blended samples were 9.2% and 8.2% higher than the parent samples of 2 and 3 mm thickness, respectively. Therefore, this study reveals that the addition of graphene platelet nanopowder with the parent material has increased the strength of the composite tremendously.
