| Abstract Scope |
Carbon nanotube (CNT), reinforced metal matrix composites have been shown to exhibit exceptional properties, especially in lightweight materials. While this has been demonstrated under laboratory conditions, there are numerous challenges that need to be overcome to scale to industry. A key challenge is the deagglomeration of carbon nanotubes requiring breaking up and dispersing clusters. One promising method is ultrasonic treatment that has been shown to deagglomerate and disperse CNTs in liquids.
A programme of experimental and numerical work has been undertaken using water as an analogue for the alloy melt to explore the underlying mechanisms in more detail. Fluid flow and bubble dynamics are both intimately coupled into the break and dispersion of CNTs. Our numerical modelling predicts how both flow and bubble dynamics are affected by changes to surface tension and is validated by experimental data in the form of high-speed in situ optical imaging. |
