Impact Properties of Coated Engineering Plastics

摘要

In this study the surface embrittlement of coated plastics was determined atvarious temperatures and strain rates as a function of the level of adhesion between coating and substrate, the coating thickness and the ductility of the coating. For this reason, coated plastic samples were used for which these parameters were varied systematically. To determine the influence of the level of adhesion and the coating ductility on the mechanical properties of coated plastics, it was found necessary to develop new test methods for the quantitative measurement of these properties. A very ductile, rubber-modified polyamide-66/polyphenylene ether-blend (IM PA66/PPE) was used as a model substrate.
