The main objective of thisproject is to improve product reliability using insight in micro-scaledeformat ion mechanisms at the polymer-steel interface and the interplay betweenmicro- deformation and de-adhesion. The microstructural evolution near theinterface and its interrelation with the evolution of the interface geometryand interface bonding is key to understand and model the behaviour of thelaminates.
This project aims to clarify the microscopic processes that determine polymer-metal adhesion during forming. Deformation and delaminationprocess es on multiple scales will be studied numerically and experimentally. Tothis purpose, the evolution of the interface structure which is related to bothsubstrate roughening and coating deformation, will be investigated. The projectis organized in two workpackages.
Workpackage A concentrates on the small-scaleexperime ntal work that will be carried out in Groningen University(RuG – supervisors: Dr. W.P. Vellinga, Prof. J. de Hosson). This workpackageconcentr ates on the study of interface evolution in realistic samples and modelsystems, whereby FIB/SEM will be used to: (1) analyze deformed polymer-metalinterf aces; (2) characterize the interface microstructure; (3) assess damage atthe interface. The analysis on the model systems involves the processing of themicro-samples, applying deformation and imaging the resulting
interface evolution.
