A Novel Approach to Determine Permeability for Cost-Effective Manufacturing of Thermoplastic Matrix Composites. The permeability (resistance of a porous rigid body to a permeating fluid) is an essential parameter for predicting impregnation quality in processing of thermoplastic composite materials.

The permeability (resistance of a porous rigid body to a permeating fluid) is an essential parameter for predicting impregnation quality in processing of thermoplastic composite materials. No reliable method exists yet to estimate permeabilities without time-consuming and cost intensive experiments. The aim of the proposed research project is to obtain a basic knowledge in determining permeabilities of fibre architectures by taking into account their stochastic properties. An innovative approach, based on characterisations of meso-structures of fibre network and simulation of computational fluid dynamics, will be developed to accurately determine permeabilities. The outcome will enable more cost-effective manufacturing of thermoplastic matrix composites.Read moreRead less

Biopolymer based plastics (eg starch and proteins from plants; polylactic acid from wastes) are made from renewable sources and are readily biodegradable, making them good substitutes for synthetic plastics for uses like packaging and agricultural film.
Some biopolymer plastics properties (eg water migration barrier, strength) are not as high as synthetic plastics. Creating nano-biocomposites (biopolymer plastics mixed with low levels of nano particles) will improve the properties of biopolymer plastics, giving novel materials that can be substituted for synthetic plastics in a wider range of applications.
These products will reduce our environmental impact, and also create economic benefits from novel, high-value nano-biocomposites.Read moreRead less

Most light alloys are strengthened by highly dispersed nanoscale precipitates. The mechanical behaviour of these alloys is determined by the intimate coupling between precipitate microstructure (size, shape and spatial distribution) and dislocation activities (by-pass, shearing and adsorption at interfaces). By integrating state-of-the-art experimental characterization and computer simulation techniques, this project aims to reveal detailed and accurate deformation mechanisms in these alloys. The knowledge gained and models developed are expected to provide guidelines to the optimization of existing alloys and design of new alloys, which is expected to create substantial wealth for Australia.Read moreRead less
