Bioinspired interfaces for improved carbon fibre composite performance. Carbon fibre composites, where carbon fibres are embedded in a polymer matrix, are gradually replacing traditional materials such as steel. For example, composites make up 50 per cent of Boeing’s 787 Dreamliner, resulting in a 20 per cent improvement in fuel economy. There is significant scope for improving the damage tolerance of these materials.

Carbon fibre composites, where carbon fibres are embedded in a polymer matrix, are gradually replacing traditional materials such as steel. For example, composites make up 50 per cent of Boeing’s 787 Dreamliner, resulting in a 20 per cent improvement in fuel economy. There is significant scope for improving the damage tolerance of these materials. A fundamental lack of understanding around the fibre matrix interface currently limits the development of new composite systems to overcome the problems with damage tolerance. This project takes inspiration from nature to develop a fundamental understanding of the interfaces within carbon fibre composites and optimise their behaviour via model-guided surface and interface engineering.

Self-reinforced biopolymer composites. This project will pioneer high performance and biodegradable composites using self-reinforced biopolymer composites. Composites can have poor properties due to interfacial issues, and this reduces their performance. By producing a fully self-reinforced (where the fibre and the polymer are the same type of polymer) polymer composites, the project will develop a way to improve properties, increase the use of biobased materials, and improve recyclability and b ....Self-reinforced biopolymer composites.

A Novel Approach to Polymer/Nanosheet Composites and Their Fundamentals. Multifunctional Polymer/nanosheet composites have not yet been widely scaled up in polymer processing and composite industries mainly due to cost and inhaling hazard. This project proposes a novel methodology which embeds nanosheet preparation within polymer melt to both remove the inhaling hazard and lower the cost; the key is to develop two groups of nanosheet intercalation compounds which can expand at the polymer proces ....A Novel Approach to Polymer/Nanosheet Composites and Their Fundamentals. Multifunctional Polymer/nanosheet composites have not yet been widely scaled up in polymer processing and composite industries mainly due to cost and inhaling hazard. This project proposes a novel methodology which embeds nanosheet preparation within polymer melt to both remove the inhaling hazard and lower the cost; the key is to develop two groups of nanosheet intercalation compounds which can expand at the polymer processing temperature, to exfoliate and disperse nanosheets in polymers. It is expected to generate new knowledge of the structure-property relationships and fracture mechanisms of these composites, for industry to scale up this technology and to develop new product.Read moreRead less

This project aims to develop high-performance bio-based flame retardants (FRs) by designing a novel core-shell nanofibrous FR system, combining exceptional flame retardant qualities and mechanical reinforcement to enhance the safe use of thermoplastic products. Thermoplastic products are widespread in building, electric and electronic, automobile and packaging products, but their intrinsic flammability poses great fire threats to the society. Flame retardants are key to producing fire-resistant plastic products with a low fire hazard rating. The novel bio-based flame retardant material developed by this project seeks to combine enhanced flame retardant properties and mechanical reinforcement functions. The outcomes of the project will demonstrate eco-friendly flame retardants and high performance flame retardant thermoplastic products.Read moreRead less

Polymers with controllable networks. This project aims to understand the mechanism and molecular level factors controlling the network flexibility, reversibility and rapid curing of cross-linked polymer structures. A highly formable, rapidly curing polymer network could improve manufacture of composites where a fibre material is embedded in a polymer matrix. The key challenges for these materials are achieving high rates of production (one part per minute) and end of life recyclability. Expected ....Polymers with controllable networks.

It has been found that, presumably because of this harsh environment, they are uniquely easy to break down into ultra-long, thin cellulose nanofibrils. Through the use of novel catalysts and advanced processing techniques, this project aims to take advantage of this trait to deliver the cost-effective production of high strength, sustainable carbon fibres from nanocellulose. It is expected that the use of the world's first university based research facility capable of producing high quality carbon fibre (CarbonNexus) will ensure the product is industrially relevant, with real potential to capture a share of the $14 billion carbon-fibre-composite market.Read moreRead less
