dc.description.abstractThe purpose of this study is to determine whether a relationship exists between the mean surface roughness Ra of an aluminium sample and the interfacial bonding strength σ between it and ice that has been frozen onto its surface. A method of forced vibration of a cantilevered composite beam at 10.0 Hz was used to study the interfacial fracture of the metal-ice interface. Low-cost strain gauges instead of piezoelectric PVDF sensors used in other reported studies were used for the adhesion strength measurements. It was found that increasing surface roughness would lead to a higher interfacial bonding strength, although there was no clearly defined mathematical relationship between Ra and σ. For smooth beams, the adhesion strength was found to be between 0.142 and 0.267 MPa, which was in good agreement with the range of values reported in other studies. © 2010 IOP Publishing Ltd.
