Interface Engineering of Multilayer Nanostructures. Nanostructured multilayers can outperform coatings of their constituent layers in both hardness and strength. It is believed that the nature of interfaces in these materials is critical since they mediate dislocation motion and crack propagation.

Nanostructured multilayers can outperform coatings of their constituent layers in both hardness and strength. It is believed that the nature of interfaces in these materials is critical since they mediate dislocation motion and crack propagation. This project will use advanced synthesis, microanalysis and theoretical methods to investigate multilayer coatings with sharp, diffuse and rough interfaces in order to reveal their failure mechanisms under stress. This will enable us to understand the principles required to design the strongest structures and facilitate the selection of materials and deposition parameters in order to produce coatings optimised for a range of demanding applications.Read moreRead less

Accurate in-situ measurement of the plasma conditions is crucial to the development of reliable new processes. This proposal will establish unique capabilities for carrying out diagnostic studies of plasma surface treatment technologies. The proposal will link Australia's most advanced plasma processing and diagnostic equipment located at the University of Sydney and the ANU to advanced materials and surface analysis facilities at La Trobe and RMIT Universities in Melbourne, using interactive e-science links and vacuum sample-transfer facilities.Read moreRead less
A Unified Approach to Determine Permeabilities of Fibre Preforms for Manufacturing Advanced Composite Structures. A unified framework is developed first time to determine 3-D permeabilities of fibre preforms for advanced fibre composites using homogenisation theories based on micro-, meso- and macro-structures of fibre preforms.

A unified framework is developed first time to determine 3-D permeabilities of fibre preforms for advanced fibre composites using homogenisation theories based on micro-, meso- and macro-structures of fibre preforms. Mechanistic models based on experimental studies, theoretical analyses and computational modelling are established to quantify permeabilities in different scales. It offers a unique technique to determine 3-D permeabilities for manufacturing advanced composite structures using various novel technologies based on resin impregnation or infusion, such as VARTM and RI. The outcomes of the project will fill the gap in the essential knowledge for cost-effective manufacturing of advanced composite structures in practical applications.Read moreRead less
Developing new, water-based lubricants for sheet metal forming. There is increasing pressure on manufacturers, including the sheet metal forming industry, to use less toxic, water-based lubricants with a number of common additives being banned or being phased out internationally. In the case of automotive manufacturers, this is combined with demand for alternative sheet materials to reduce costs or cater for export markets. Efficient development of new lubricants or replacement additives require ....Developing new, water-based lubricants for sheet metal forming. There is increasing pressure on manufacturers, including the sheet metal forming industry, to use less toxic, water-based lubricants with a number of common additives being banned or being phased out internationally. In the case of automotive manufacturers, this is combined with demand for alternative sheet materials to reduce costs or cater for export markets. Efficient development of new lubricants or replacement additives requires a comprehensive understanding of the interactions between lubricant components and the surface of the sheet metal. This project will explore and model these interactions and how they are affected by the variables in a metal forming process.Read moreRead less
