Other Research Projects

Dynamic simulation of flocculation: fractal particles in a polymer matrix

The structure of a colloidal dispersion depends sensitively on the amount of shear used during processing, on the shearing time, on the particle size, on the particle structure, and on the surface chemistry of the particles. In this project, we will explore these parameters numerically, with the specific goal of understanding filler dispersion in rubber composites.

Filler reinforcement in elastomers
Funding source: Bridgestone / Cabot Corp

Materials such as carbon black, clays and silica significantly improve the mechanical properties measured in terms of strength and fatigue resistance when compounded into elastomers. This work uses different models over a wide range of length scales to understand polymer filler interactions at the atomic scale to micro-structural finite element models at the nanoscale.

Foamed Rubbers

A hollow filler material can be used to create a closed cell foam structure. The full behaviour of this type of foamed elastomer is not well understood. The behaviour is observed in transparent elastomer materials using microscopy techniques to observe the process of bending, buckling and any dewetting at the rubber filler interface.

Friction Behaviour of Rubber

The project examines how friction behaviour depends upon elastomer compounding, surface roughness, sliding speed, temperature and surface preparation. The project uses a range of finite element analysis modelling techniques to observe how phemomenon such as Schallamach waves are formed during sliding.

Our efforts have focused on the development of tactile displays, tuneable windows and tuneable optical lenses, as highly innovative devices for biomedical and bioinspired mechatronic systems.

Prosthetic heart valves must be both durable and bio-compatible. The Structured Materials group at Cambridge University has developed an injection moulded polymeric heart valve whose fatigue performance is being evaluated. Prototypes must exceed a billion cycles in accelerated fatigue tests, to ensure a reliable lifetime prediction in service.
