Qian H, Bismarck A, Greenhalgh ES, Shaffer MSPet al., 2010, Carbon nanotube grafted carbon fibres: A study of wetting and fibre fragmentation, Composites Part A, Vol: 41, Pages: 1107-1114

Carbon nanotubes (CNTs) were grafted on IM7 carbon fibres using a chemical vapour deposition method.The overall grafting process resulted in a threefold increase of the BET surface area compared to the original primary carbon fibres (0.57 m2/g). At the same time, there was a degradation of fibre tensile strength by around 15% (depending on gauge length), due to the dissolution of iron catalyst into the carbon;the modulus was not significantly affected. The wetting behaviour between fibres and poly(methylmethacrylate) (PMMA) was directly quantified using contact angle measurements for drop-on-fibre systems and indicated good wettability. Single fibre fragmentation tests were conducted on hierarchical fibre/PMMA model composites, demonstrating a significant (26%) improvement of the apparent interfacial shear strength (IFSS) over the baseline composites. The result is associated with improved stress transfer between the carbon fibres and surrounding matrix, through the grafted CNT layer. The improved IFSS was found to correlate directly with a reduced contact angle between fibre and matrix.

Qian H, Greenhalgh ES, Shaffer MSP, Bismarck Aet al., 2010, Carbon nanotube-based hierarchical composites: a review, Journal of Materials Chemistry

The introduction of carbon nanotubes (CNTs) into conventional fibre-reinforced polymer composites creates a hierarchical reinforcement structure and can significantly improve composite performance. This paper reviews the progress to date towards the creation of fibre reinforced (hierarchical) nanocomposites and assesses the potential for a new generation of advanced multifunctional materials. Two alternative strategies for forming CNT-based hierarchical composites are contrasted, the dispersion of CNTs into the composite matrix and their direct attachment onto the primary fibre surface. The implications of each approach for composite processing and performance are discussed, along with a summary of the measured improvements in the mechanical, electrical and thermal properties of the resulting hierarchical composites.

Hierarchical composites introduce nanoscale fillers into the matrix of conventional fibre composites, in order to address critical failure modes. The effectiveness of growing carbon nanotubes onto primary fibres is reported at the single-fibre level. The success of an analogous, entirely renewable and biodegradable hierarchical composite system provides encouragement to scale-up.
