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.
Novel quantitative sizing of inaccessible and hard-to-inspect defects to address the challenges posed by innovations in airframe design. Modern unitised aircraft structures cannot be reliably inspected using traditional techniques. This project will develop new techniques to quantify defects required for this innovation in aircraft component design. This research will improve the through-life support of future metallic and composite aircraft structures and improve air safety.
Theory and methods for evaluation of microstructural fatigue damage. The microstructural damage accumulation stage often consumes a significant portion of the total fatigue life of structures. However, its progressive evaluation is beyond the reach of safety inspection techniques which are currently employed to maintain structural integrity and prevent fatigue failures. This project aims to fill this gap by developing innovative methods for the measurement of material properties related to fatig ....Theory and methods for evaluation of microstructural fatigue damage. The microstructural damage accumulation stage often consumes a significant portion of the total fatigue life of structures. However, its progressive evaluation is beyond the reach of safety inspection techniques which are currently employed to maintain structural integrity and prevent fatigue failures. This project aims to fill this gap by developing innovative methods for the measurement of material properties related to fatigue damage and establishing a new theory which links these properties to the remaining life of the structure. The project outcomes will facilitate the global trend towards predictive maintenance strategies, thereby generating substantial cost benefits, specifically, for high-value assets and ageing infrastructure.Read moreRead less
Advanced hard metals: microstructure-property-processing relationships. Our aim is to understand the origins of the properties of tungsten-carbide cobalt based hard metals and how these may be tuned via alloying and processing. This is significant because hard metals are used in industrial-scale turning, milling and drilling processes to cut other materials into finished parts with precise tolerance and surface finish. The expected outcomes are increased competitiveness of Australia's aerospace, ....Advanced hard metals: microstructure-property-processing relationships. Our aim is to understand the origins of the properties of tungsten-carbide cobalt based hard metals and how these may be tuned via alloying and processing. This is significant because hard metals are used in industrial-scale turning, milling and drilling processes to cut other materials into finished parts with precise tolerance and surface finish. The expected outcomes are increased competitiveness of Australia's aerospace, agriculture, biomedical, construction, defence, mechatronics, mining, and oil and gas industries, which depend on this materials technology. The benefits will be the creation of leading expertise in advanced manufacturing, support of end-user industries and the establishment of a regional R&D focal point in hard metals.Read moreRead less
