  • Composite damping – using magnetic and viscous mechanisms

The best mechanical properties for any materials are achieved with a selection of materials in fibrous form. It therefore makes sense to incorporate these fibres within other materials (i.e. produce a composite material) to enable fibres to be used in structures. In addition, modification of mechanical and physical properties can also be made using particulates. The combination of multiple constituent materials to produce a single material leads to increased complexity in behavioural terms compared to conventional engineering materials, and this leads to challenges in their engineering. However, many examples of their use, Black Magic and Brittan's bike to name two close to home, have demonstrated that the challenge is well worth it.

Currently, however, as relatively new materials, advanced composites pay penalties compared to conventional engineering materials in the requirement for much more conservative design. Increased knowledge of their long-term behaviour will improve this and increase their efficiency along with improving mass production techniques. As this occurs, composites will increasingly replace conventional engineering materials to give improved performance. Furthermore, technology learnt with advanced composites, commonly the regime of carbon fibre, can be applied to other composite materials including glass fibre and natural fibre based composites. Such work at Waikato University has focussed on tailoring properties of composites through fibre treatment and interfacial engineering. In addition, research has involved development of polymer matrices from bioderivable materials including a thermoplastic based on corn gluten meal and a thermoset based on glycerol. With New Zealand's resources of wood and other natural fibres, there is great potential to tap into composite design and process technology to produce improved cost efficient structural materials.
