Abstract

Underground pipeline is the safest ways to transport oil and gas. Nowadays, a lot of rehabilitation techniques and repair methods are available for onshore and offshore pipelines including the usage of Fibre-Reinforced Polymer composite. Composite repair systems involving three parts which are composite wrapper, adhesive and infill materials is most preferable techniques used for repairing damaged pipeline in oil and gas industry. High strength infill materials has the potential in improving overall repair performance. The purpose of this research is to investigate the effectiveness dispersion of graphene nanoplatelets as reinforcement to enhance the performance of epoxy grout as infill materials. By adding 0.01%, 0.05% and 0.1% of graphene nanoplatelets, the dispersion was done using a three-roll mill machine where the graphene was de-agglomerate to achieve homogenous dispersion. The mechanical properties tests were carried out in accordance to the ASTM D638 for tensile test and ASTM D695 for compressive test. The results of tensile and compression tests show increment of strength for all modified samples. The highest tensile strength was recorded at 20.89MPa for sample with 0.1% graphene and 82.67MPa for sample added 0.05% graphene for compressive strength. The strength increment was recoded range from 46% to 88% and 3% to 16% under tensile and compression test, respectively. Thus, based on the findings, graphene nanoplatelets shows the ability to improve performance for tensile and compressive properties as compared to control sample.
