Carbon fibre composites involve a polymer matrix reinforced by carbon fibres. These carbon fiber composites are known for their high strength-to-weight ratio and are becoming widely used in diverse applications such as infrastructure, fuel efficient transport systems and prosthetic limbs [1]. However, these composites are not as strong as they could be. The strength of the final composite depends not only on the carbon fibre and the matrix, but how well the fibres interact with the matrix. Effective reinforcement of the polymer requires good bonding between the fibres and the matrix at the interface [2]. Our work focuses on the interface region, improving interfacial adhesion and therefore overall composite strength through surface functionalisation techniques.
