Carbon Nexus: A strategic overview and research highlights

Carbon Nexus (www.carbonnexus.com.au) is a globally significant research facility at Deakin University focused on the manufacture and use of carbon fibre. Carbon Nexus represents a partnership between Deakin University and the Victorian Centre for Advanced Materials Manufacturing (VCAMM) and houses two production lines capable of manufacturing industrially relevant quantities of aerospace grade carbon fibre. The facility enables scientists to conduct research into the chemical, mechanical and nano-scale characteristics of new carbon fibre materials produced on site. There is a strong focus on evaluating these new carbon fibre products in composite materials, particularly composites cured using out-of-autoclave techniques. This paper will present an overview of the vision for Carbon Nexus as well as the technical capabilities of both the laboratory scale single tow line and the larger pilot line capable of producing up to 50 tons of carbon fibre per year. Both lines are fully operational and able to convert a range of polymer precursors into carbon fibre. They are representative of world's best practice for carbon fibre manufacturing methods and well suited to conducting energy efficiency studies. Highlights from recent research projects will focus on the effect of the surface treatment and sizing of carbon fibre on fibre-matrix adhesion in composite materials. In addition to this, results from studies of the effect of varying processing parameters on the structure and properties of oxidised polyacrylonitrile and carbon fibre will also be presented.
