Optimizing the Performance of Polymers and Composites

The properties of materials cannot be directly controlled: we are only able to control the structure of a material. In order to obtain the desired properties, we must first understand the complex relationship between structure and properties. Our group studies this relationship in a variety of polymers and polymer composites, with an emphasis on strength, stiffness and fracture resistance. Students interested in materials science are needed, and a typical project includes elements of both experimental and theoretical work.

Mechanical Behaviour of Composite Materials

We study the fundamentals of composite reinforcement in short fibre composite materials. We have recently published novel and simplified models for polymer composite viscoelasticity, and will use this framework to understand long term performance of composites.

Additive Manufacturing

Additive manufacturing, or 3D printing, is a method of producing solid objects by building them layer-by-layer on a platform using a digitally controlled deposition process. In order to produce structurally sound materials from polymers, fibres can be added to provide reinforcement. We study the 3D printing and the resultant properties of fibre composites produced on both thermoplastic and thermosetting 3D printing systems. While the mechanics of composite materials are well understood, the production of composites using 3D printing is still in its infancy.
