The effects of graphitisation temperature and drawing on the tensile and compression properties will be discussed. Various models that have appeared in the literature over the last 40-50 years to account for structure-mechanical property behaviour in carbon fibres will be presented in brief and their relation to experimental data will be discussed.
Past work on the micromechanics of reinforcement of model composite systems consisting of continuous high-modulus (HM) as well as intermediate modulus carbon fibres embedded in an epoxy resin will be reviewed. It will be shown how laser Raman Spectroscopy can be employed to determine the development of stress and strain in the fibre at the micron level and the derivation of the interfacial shear stress profile that governs the stress-transfer characteristics and failure processes at the interface. Similar results obtained from full composite systems that contain a discontinuity such as a fibre break or fibre end will be presented as well. Overall, the effect of fibre/ polymer interface.[/dt_banner][/vc_column][/vc_row]
