Understanding multi-scale reinforcement of carbon fibre composites. Addition of nano scale entities, such as nanotubes, on the surface of a carbon fibre forms a bottle-brush like architecture and strengthens fibre-matrix interface. This project will pioneer development of a systematic approach for analysis and design of such multi-scale reinforced composite materials for use in aerospace and civil industries.

This project intends to improve our understanding of the influence of surface stress on bending in anisotropic crystalline plates. Micro/nanoelectro-mechanical systems as transducers, switches, logic gates, actuators and sensors are widely used in fields of biotechnology, medicine, automotive, civionics, avionics and defence. A key issue that affects the accuracy and reliability of these systems is how to correctly predict the size-dependent surface stress of the structural components in the systems. The project aims to quantify the relations between the change in surface stress and the bending of structures with micro/nanoscale thickness and arbitrary crystallographic symmetry. Expected project outcomes may lead to significant advancement in overcoming the current shortcomings in designing micro/nanoelectro-mechanical devices.Read moreRead less

Achieving structural morphing via functionalising nonlinear buckling. This project aims to develop a general framework to analyse and design functional components of buildings and structures, where they change shapes (morphing) by buckling. Australian buildings consume 20% of the nation’s total energy production on heating and cooling, and projected population increases are likely to increase energy demands. The shape changes are optimised, e.g. to reduce energy consumption by minimising solar r ....Achieving structural morphing via functionalising nonlinear buckling. This project aims to develop a general framework to analyse and design functional components of buildings and structures, where they change shapes (morphing) by buckling. Australian buildings consume 20% of the nation’s total energy production on heating and cooling, and projected population increases are likely to increase energy demands. The shape changes are optimised, e.g. to reduce energy consumption by minimising solar radiation loads or maximising natural air ventilation. The project expects to develop building technology solutions to reduce Australia's energy consumption, and provide domestic and global market opportunities in the high-tech manufacturing sector.Read moreRead less
