The tensile strength of current generation carbon fibre is limited by fibre defects. Further fundamental understanding is required to reduce these defects and increase the tensile properties of carbon fibre. The suite of instruments available for micro and nano-scale fibre characterisation at Carbon Nexus allows in-depth understanding of the reasons for such defects.
Recent work has shown that incorporating carbon nanotubes into PAN precursor can improve properties in carbon fibres. Challenges for this work include scaling up costs associated with nanoparticles and successful dispersion of carbon nanotubes in the polymer matrix for larger volume production.
Carbon Nexus has a partnership with researchers in the Centre of Excellence for Electromaterials Science at the University of Wollongong to develop new nanostructured precursors based on low-cost graphene oxide particles.
