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
Development of PVC-Based Polymer Nanocomposites. The aim of the project is to develop a PVC polymer nanocomposite material to be used in water pipelines. It has been found that the inclusion of a nanoparticle phase, in this case calcium carbonate, leads to increases in strength, stiffness, toughness and abrasion resistance. This proposed project will develop and assess an optimum material in addition to investigating the mechanisms of deformation.

This project aims to engineer and scale up production of biodegradable injection molded products with tailored properties, processing and biodegradation. Specifically we will focus on novel materials and processing technologies in tandem with biodegradation understandings to expand the utilization of starch-based polymers. We will then combine fundamental rheological and polymer processing skills with and product development experience from both universities and the industrial partner (Plantic Technologies) to scale up processing and develop successful biodegradable products. This project will also enable an Australian owned start-up company with a broad shareholder base to generate significant export income through key commercialization.Read moreRead less
Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of ....Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of the road asset exceeds $106,000 million. Thus providing satisfactory tough protective shield on asphalt pavements that locks out destructive elements and provide long-term protection is of enormous economic importance and national/community benefit.Read moreRead less

The project aims to develop advanced new material for multilayered packaging with high oxygen and moisture barrier properties for cost effective packaging applications. Poly Products currently imports and uses some polymer as its key component for controlling barrier property of their food packaging. However, the new nanostructured material when sandwiched between less expensive materials in a multilayered packaging film will yield excellent barrier properties, leading to extended shelf life of different food products. The new smart material will generate significant material saving and replace the imported polymer, and will secure export market of the product in Asia -Pacific region.Read moreRead less
