Fibrous fabrics with differential transplanar transport properties for moisture and water. The project develops a framework for the development of fibrous fabrics with desired differential transplanar transport properties for moisture and water, integrating various transport mechanisms with hierarchical microstructures of the fabrics. The results will lead to the development of new fabrics for the local and overseas apparel industry.
Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously gen ....Novel plastics using renewable signal chemistry to remove bacteria in water. This project plans to develop synthetic plastic surfaces that continuously generate nitric oxide to deter the formation of biofilms. Plastic surfaces exposed to aqueous environments rapidly become covered by a film of bacteria, which can cause infection. Trace levels of generated nitric oxide can combat this problem by breaking up existing bacterial biofilms. Current research has developed plastics that continuously generate nitric oxide, but not for extended periods of time. This project’s approach is significant because it avoids bacterial resistance to the nitric oxide treatment. Applications of this technology may include removing biofilms from environments such as water filtration devices and consumable medical surfaces.Read moreRead less
Experimental validation of the strain invariant failure theory for carbon/epoxy composites. The project will be of national and international benefit, through providing a validated, enhanced design capability for advanced composite materials. Greater depth of understanding of such materials will allow more efficient structures to be designed in applications requiring high strength and stiffness, low weight, and resistance to corrosion and fatigue. Such applications include the aerospace, offshor ....Experimental validation of the strain invariant failure theory for carbon/epoxy composites. The project will be of national and international benefit, through providing a validated, enhanced design capability for advanced composite materials. Greater depth of understanding of such materials will allow more efficient structures to be designed in applications requiring high strength and stiffness, low weight, and resistance to corrosion and fatigue. Such applications include the aerospace, offshore and mining industries. There are, therefore, far-reaching benefits in industries important to Australia. In addition, the reputation of the Australian aerospace research industry will be promoted through a collaborative association with Boeing, a world leader in development of commercial aircraft.Read moreRead less
Durability of carbon fibre reinforced polymer (CFRP) strengthened steel structures against environment-assisted degradation. This research project will challenge conventional methods of repairing or strengthening steel structures by using carbon fibre reinforced polymer with advanced epoxy. The outcome of this research is to remove the biggest barrier to the full utilization of such advanced material in civil, offshore and mining industry.

Designing starches for increased productivity in mineral flotation. This project aims to understand the process of starch-mineral surface interactions, and design and develop tailored starch depressant/flocculant biopolymers for mineral beneficiation via the froth flotation process. Natural and modified starches are used as depressants and flocculants in mineral flotation, but scientists lack knowledge of mechanisms describing starch-mineral surface interactions, particularly how they process base metal sulphides. This project also intends to develop starch characterisation techniques and novel methods for modifying starch structures and functionalities. Anticipated outcomes are new novel manufacturing applications for starch in Australia.Read moreRead less
