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.

Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper bound ....Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper boundary conditions for viscoelastic flow at interfaces between a flowing fluid and a solid surface. This vital area has not been thoroughly studied theoretically and computationally, and we seek to clarify the mechanisms by using molecular dynamics.Read moreRead less

Structure-Property Relationships of Polymers with Controlled Architecture. Mechanical properties of a polymer (e.g., how elastic it is and how it dissipates energy when compressed) govern how well it performs as an adhesive, or its behaviour when melted and shaped into a consumer item. This project aims to relate molecular architecture to mechanical properties, using new techniques which permit the creation of polymers wherein each architectural characteristic is separately controlled. This has ....Structure-Property Relationships of Polymers with Controlled Architecture. Mechanical properties of a polymer (e.g., how elastic it is and how it dissipates energy when compressed) govern how well it performs as an adhesive, or its behaviour when melted and shaped into a consumer item. This project aims to relate molecular architecture to mechanical properties, using new techniques which permit the creation of polymers wherein each architectural characteristic is separately controlled. This has the potential to develop fundamental understanding for structure-property relations for the type of branched polymers that are in common use in industry and for which adequate models do not currently exist.Read moreRead less
