Determination of the Properties of Hyper-Elastic Materials by Deep Indentation. We seek to develop the scientific basis for the interpretation of the results of "deep" indentation testing of non-linear elastic (hyper-elastic) materials. Simple tests (such as indentation) produce complex strain fields. Interpretation of the resulting data in terms of stiffness, for example, requires a complex model of the deformation process that can be utilised to link the observed behaviour to the basic prope ....Determination of the Properties of Hyper-Elastic Materials by Deep Indentation. We seek to develop the scientific basis for the interpretation of the results of "deep" indentation testing of non-linear elastic (hyper-elastic) materials. Simple tests (such as indentation) produce complex strain fields. Interpretation of the resulting data in terms of stiffness, for example, requires a complex model of the deformation process that can be utilised to link the observed behaviour to the basic properties of interest. This project is dedicated to an understanding of the complex deformation associated with large strain indentation of hyper-elastic materials and structures, development of finite element based models for this deformation and creation of techniques for interpretation of the results of such indentation tests.Read moreRead less
Failure modes in ceramic-based layer structures: Relevance to failure of dental crowns. With the aging of our population, issues concerning the lifetime of biological system are paramount to the quality of life and economic well being of our society. This project is closely linked to the development of prosthetic materials and structures that will improve performance and life of biomechanical devices, by providing better understanding to the mechanics of failure and failure origins of ceramic-ba ....Failure modes in ceramic-based layer structures: Relevance to failure of dental crowns. With the aging of our population, issues concerning the lifetime of biological system are paramount to the quality of life and economic well being of our society. This project is closely linked to the development of prosthetic materials and structures that will improve performance and life of biomechanical devices, by providing better understanding to the mechanics of failure and failure origins of ceramic-based dental crowns and restorations, and to develop materials that will withstand exacting conditions - in body fluids - over extended lifetimes. Crown replacement is by far the most widespread of all prosthetic procedures. This project promises to help bridge the gap between physical and medical science in Australia. Read moreRead less
Engineering a silk fibroin based ear drum with optimum acoustic properties. This project will use new silk fibroin materials to develop ear drums with improved acoustic properties. This will lead to significant improvement in the quality of life of nearly 2.5 million people in Australia who are affected by hearing loss and further strengthen Australia's leading position in this area.
Novel microwave processing of carbon nanotube/thermoplastic composites. This project aims to develop a novel fabrication process for carbon nano-tube (CNT) / thermoplastic composites. The method, with lab based ‘proof of concept’, uses microwaves and overcomes problems of dispersion and aggregation of CNTs, which limit properties of the nano-composites. At lab scale, a 50 per cent increase in stiffness of polypropylene and an increase in electrical conductivity with the addition of 0.5 weight pe ....Novel microwave processing of carbon nanotube/thermoplastic composites. This project aims to develop a novel fabrication process for carbon nano-tube (CNT) / thermoplastic composites. The method, with lab based ‘proof of concept’, uses microwaves and overcomes problems of dispersion and aggregation of CNTs, which limit properties of the nano-composites. At lab scale, a 50 per cent increase in stiffness of polypropylene and an increase in electrical conductivity with the addition of 0.5 weight percent CNT has been demonstrated. This project should unravel mechanisms by which these outstanding property improvements are achieved and will scale up the process to industrial level. Expected outcomes will be economical, lighter and stronger plastics for manufacturing applications such as rotational molding, transport and electronic packaging.Read moreRead less
High performance polymer fibres for recyclable composites . The project aims to develop novel drawn polymer fibres with aligned carbon nanotubes incorporated inside and also grafted nanotubes on their surface. Such polymer fibres can be used to reinforce thermoplastics to make high performance composites with effective recyclability. This is important as the existing thermosetting composites are not recyclable and significant property enhancement require high loading (>30%) of reinforcing fibres ....High performance polymer fibres for recyclable composites . The project aims to develop novel drawn polymer fibres with aligned carbon nanotubes incorporated inside and also grafted nanotubes on their surface. Such polymer fibres can be used to reinforce thermoplastics to make high performance composites with effective recyclability. This is important as the existing thermosetting composites are not recyclable and significant property enhancement require high loading (>30%) of reinforcing fibres. The outcomes of this project will be novel technology for making high stiffness polymer fibres and their use in thermoplastic composites. The benefits will be to allow easy processing and recycling. They will be used in down-sizing of high volume products and high value automotive or aerospace products.Read moreRead less
Helium recovery from liquefied natural gas waste stream using nanoporous mxene materials. The waste streams from many liquefied natural gas (LNG) industries still contains valuable helium, a possible next mineral to sustain our economic growth. This project aims to efficiently separate helium from methane and nitrogen via the layered two dimensional materials.

The waste streams from many liquefied natural gas (LNG) industries still contains valuable helium, a possible next mineral to sustain our economic growth. This project aims to efficiently separate helium from methane and nitrogen via the layered two dimensional materials. This project will seek to understand the assembling behaviour of these nano-sized Mxene flakes and their molecular sieving properties. Australia is playing a leading role in the global liquefied natural gas (LNG) production and trade. This project expects to further position Australia at the forefront of intellectual leadership in the field of gas processing and material development. This will have significant benefits, such as further improving these LNG projects economics by cost-effectively producing helium as a valuable by-product via advanced porous nano-materials.Read moreRead less
