Composite Materials
Current research covers interfacial phenomena in composite materials, natural composites and rapid composites manufacture. The deformation mechanics of a range of high performance synthetic reinforcement fibres for composites are explored, as are those of natural and regenerated cellulose fibres.
In the later case the main emphasis is on understanding the relationships between the microstructure and molecular structure of these materials and their mechanical properties. Molecular dynamics modelling together with experimental studies have been used to gain an improved insight into the behaviour of natural fibres.
The Northwest Composites Centre is a collaboration which incorporates researchers from several Schools in the University of Manchester, together with colleagues from the universities of Liverpool, Lancaster and Bolton covering a wide range of polymer and metallic composites. The hub of this activity is based within the School of Materials and has facilities for rapid processing of composites through a variety of new technologies, including microwave and radio frequency heating as well as Quickstep. There are also extensive facilities for the characterization of composites.
Research themes

Facilities
- Quickstep Technology Processing
A recently developed technique for rapid processing of composites using a heat transfer fluid rather than a metal mould.
- Microwave Processing
Heat transfer is often an issue limiting heat up rates. This can be overcome by microwave heating since the energy transfer does not rely on conduction.
- Robotic Tow Placement
A facility for robotic tow placement is being developed. Using our expertise in textile structures we will research methods for through thickness placement of reinforcement.
- C-Scan and X-Ray Imaging Facility
We have a large range of characterisation apparatus including C-scan and X-ray tomography.
- Impact Testing
Through our partners we have access to a range of impact testing facilities, including drop-weight and ballistic testing.
- Textile Structures
We have facilities to design and manufacture a wide range of textiles structures including 3D woven, braided and knitted structures and to manufacture prepregs or composites from them.
