AB  - A current design limiting aspect of unidirectional carbon fibre reinforced polymer composites is their lack of strength in compression compared to tensile loading. To improve the compressive performance of carbon fibre reinforced polymer, it is critical to understand how failure occurs at each constituent length scale. One way to achieve this is to produce model composites, which address this at the single fibre level. In this study, Raman spectroscopy is used as a stress-sensing technique to analyse the micromechanical response of a range of single carbon fibres in compressive loading. The experimental procedure to produce single fibre compressive stress-strain curves for two high modulus carbon fibres are reported and discussed. An additional technique to utilise Raman spectroscopy to carry out point-to-point, spatially resolved stress mapping a long a length of fibre, from which interfacial shear stress characteristics can be derived is reported. The experimental setup has simpler sample design and preparation methods than other single fibre compression testing techniques, whilst being versatile in the measurements that can be obtained from various carbon fibre types.
