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

Designing starches for increased productivity in mineral flotation. This project aims to understand the process of starch-mineral surface interactions, and design and develop tailored starch depressant/flocculant biopolymers for mineral beneficiation via the froth flotation process. Natural and modified starches are used as depressants and flocculants in mineral flotation, but scientists lack knowledge of mechanisms describing starch-mineral surface interactions, particularly how they process base metal sulphides. This project also intends to develop starch characterisation techniques and novel methods for modifying starch structures and functionalities. Anticipated outcomes are new novel manufacturing applications for starch in Australia.Read moreRead less

This project aims to develop a novel fabrication process for carbon nano-tube (CNT) / thermoplastic composites. The method, with lab based ‘proof of concept’, uses microwaves and overcomes problems of dispersion and aggregation of CNTs, which limit properties of the nano-composites. At lab scale, a 50 per cent increase in stiffness of polypropylene and an increase in electrical conductivity with the addition of 0.5 weight percent CNT has been demonstrated. This project should unravel mechanisms by which these outstanding property improvements are achieved and will scale up the process to industrial level. Expected outcomes will be economical, lighter and stronger plastics for manufacturing applications such as rotational molding, transport and electronic packaging.Read moreRead less
