Indentation, creep and axial–torsional fretting wear analysis of PC/ABS blends

Abstract

PC/ABS is a polymer blend widely used due to its nearly additive combination of the best properties of its components. However, there is almost no literature available regarding its failure behavior while under compression loading. This work presents sphere-to-flat experimental analyses of four PC/ABS weight ratio compositions: 100:0, 80:20, 65:35 and 0:100. Specimens are tested for indentation, creep and axial–torsional fretting wear at severe loads. Moreover, the contribution of each one of these three failure phenomena is determined and discussed. Creep has a major effect in most materials, while fretting wear is particularly critical to the 100:0 and 80:20. The 65:35 blend exhibited the best results in all test conditions, making it a good candidate for various industrial applications.
