Fatigue thresholds, crack initiation and small crack growth phenomenon in uPVC, mPVC and Oriented PVC pipes. Unplasticised polyvinylchloride (uPVC) is currently used for water reticulation pipelines. These are subject to variable pressure which can lead to fatigue failures. Improved materials, modified PVC (mPVC) and oriented PVC (oPVC), are now entering this market. uPVC shows a fatigue threshold when prenotched samples are tested. The fatigue threshold is an important design concept since it r ....Fatigue thresholds, crack initiation and small crack growth phenomenon in uPVC, mPVC and Oriented PVC pipes. Unplasticised polyvinylchloride (uPVC) is currently used for water reticulation pipelines. These are subject to variable pressure which can lead to fatigue failures. Improved materials, modified PVC (mPVC) and oriented PVC (oPVC), are now entering this market. uPVC shows a fatigue threshold when prenotched samples are tested. The fatigue threshold is an important design concept since it represents the stress amplitude below which fatigue failures should not occur. Its existence in unnotched pipes and in the newer PVC materials is uncertain. This project will quantify fatigue thresholds and the mechanisms involved in crack initiation in uPVC , mPVC and oPVC.Read moreRead less

Novel Tough Polymer Composites. Advanced composites are used in high value-added applications such as computer chip packaging and aerospace applications. In these applications epoxy systems are used despite their inherent brittleness. Much research has focused on toughening epoxy systems, but most tougheners cause a reduction in processing or material properties. This project focuses on developing novel epoxy tougheners during the polymerisation of the epoxy-based composite. Specifically we will ....Novel Tough Polymer Composites. Advanced composites are used in high value-added applications such as computer chip packaging and aerospace applications. In these applications epoxy systems are used despite their inherent brittleness. Much research has focused on toughening epoxy systems, but most tougheners cause a reduction in processing or material properties. This project focuses on developing novel epoxy tougheners during the polymerisation of the epoxy-based composite. Specifically we will use novel hyperbranched [star-like] polymers that have excellent processing properties, high reactivity for structure control and the ability to control toughening at the molecular and macroscopic level to produce novel technology for advanced composites.

Confronting the Challenges in Modern Spectroscopy of Polymers. Polymers and nanocomposites are increasingly being used in new, high value applications as diverse as medicine, structural engineering, optics and electronics. In order to control and understand polymer performance, a detailed knowledge of the chemical structure at all stages in their lifecycle is required - in the liquid, rubber and solid states and during degradation.

Polymers and nanocomposites are increasingly being used in new, high value applications as diverse as medicine, structural engineering, optics and electronics. In order to control and understand polymer performance, a detailed knowledge of the chemical structure at all stages in their lifecycle is required - in the liquid, rubber and solid states and during degradation. This application seeks to establish a coordinated Polymer Spectroscopy Network using new forms of infrared and NMR spectroscopy to probe samples (usually of an non-planar geometry) in a range of configurations. These will be used simultaneously with other techniques such as rheology or thermogravimetry, and will produce capabilities unique in Australia.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
