Alias Othman, . The role of metal surface asperities in determining the strength of rubber to metal bonds. pp. 169-182. ISSN 0127-7065
Abstract
The strength of the rubber to metal bonds has been observed to be dependent on the direction of failure propagation. Examination of metal surfaces revealed that the differences in the types of bond failure and hence the bond strength when the direction of failure propagation in the 90peel test was reversed was associated with the asymmetrical structure of the asperities on the metal surface. These asperities with different slopes on their opposite sides gave rise to different degrees of difficulty in dislodging the rubber from the crevices thus giving different types of failure. Peeling from sides having the steeper slope resulted in bulk failure and hence a higher bond strength while peeling from the side with gentle slope resulted in a combination of rubber and interfacial failures thus a lower bond strength. This was confirmed from the scanned of the metal surfaces and also from model experiments.
