“…Considering its storage and transportation applications, gas permeability of the CFRP composite has also been investigated. For the well-cured composite, gases could pass through the free volume of the epoxy matrix under diffusion-controlled mechanism, driven by the concentration gradient [39][40][41][42][43]. In order to improve the barrier properties, thin-ply [44], Al 2 O 3 nanoparticles [45], clay-based film [46,47], aluminium foil [48] and surface coatings [49] have been applied to the CFRP composites.…”

Carbon-fibre-reinforced polymer (CFRP) composites are promising materials for non-metallic pipe applications in the oil and gas industry owing to their high corrosion resistance, specific strength and stiffness. However, CFRP has poor gas barrier performance meaning that a liner has to be inserted. Graphene-based nanomaterials have been demonstrated to improve gas barrier properties in thermoplastic polymers, and thus, a CFRP–graphene hybrid composite could provide an alternative to lined pipes. In this work, a method combining spray coating with vacuum-assisted resin infusion was developed to fabricate CFRP hybrid composites with preferred in-plane aligned graphene nanoplatelets. Tensile and flexural properties, as well as CO2 gas permeability, were evaluated. It was illustrated that both tensile and flexural properties performed better under relatively low GNP loadings (< 0.2 vol%), while gas barrier property was significantly improved with the increasing GNP loadings which fits the Nielsen model with an effective GNP aspect ratio of 350.
