“…The low Vf of the F-CFRP should lead to improvements in the tensile properties once normalised for Vf, although these could yield an underestimate, as composites with low Vf tend to have a random distribution of fibre orientation [42]. Further work should be carried out to assess the theoretical prediction of Vf normalising nano-modifed composites for the low Vf quoted.…”

We report improvements for sizing-sensitive mechanical and physical properties, such as the interfacial adhesion, shear properties and handling of the fibres, whilst retaining resin-infusion capability. Following fibre volume fraction normalisation, the carbon nanotube-modified carbon fibre composite offers improvements of 146 % increase in Young's modulus; 20% increase in ultimate shear stress; 74 % increase in shear chord modulus and an 83 % improvement in the initial fracture toughness. The addition of CNTs imparts electrical functionalisation to the composite, enhancements in the surface direction are 400%, demonstrating a suitable route to sizing-free composites with enhanced mechanical and electrical functionality.

“…Whilst the quasi-static behaviour of FRP materials has been generally well studied, e.g. [1], their behaviour at increased strain rates and during subsequent service life are less well defined [2], making damage-tolerant design challenging. Typical sources of high strain rate damage include a bird strike or hail impact on a wing leading edge, an explosive blast near a military vehicle or slamming encountered by small vessels in rough seas.…”

A novel methodology for the synchronised capture of high resolution white-light and infra-red (IR) images during a fatigue test is described. The approach allows digital image correlation (DIC) and thermoelastic stress analysis (TSA) to be applied practically simultaneously without the requirement to pause the cyclic load. The methodology is demonstrated on cross-ply carbon-epoxy specimens that have experienced damage induced by intermediate strain rate loading. Similar undamaged specimens are studied and the results from each compared.Various damage types are identified which include transverse cracking, delaminations and longitudinal splitting. The results are verified using X-ray computed tomography (CT).
