Methods for Polymer Diagnostics for the Automotive Industry*

Verfahren zur Polymerdiagnose für die Automobilindustrie
Wolfgang Grellmann and Beate Langer
From the journal Materials Testing


The further development from polymer testing to polymer diagnostics leads to test methods with higher amount of information per test procedure as conventional tests. These changes contribute to fulfill the increased requirements in polymer testing and diagnostics. Selected examples of practice of industrial polymer testing show that these new methods can be applied appropriately to solve the issues of the automotive industry.


Die weitere Entwicklung der Polymerprüfung zur Polymerdiagnose führt zu Prüfverfahren mit einem größeren Informationsgehalt pro Prüfung als bei konventionellen Versuchen. Diese Veränderungen tragen dazu bei, den steigenden Anforderungen an die Polymerprüfung und —diagnose Rechnung zu tragen. Ausgewählte Praxisbeispiele aus der industriellen Polymerprüfung zeigen, dass diese neuen Verfahren geeignet sind und angewendet werden können, um Fragen aus der Automobilindustrie klären zu können.


Extended English Version of the Contribution to the Proceedings Werkstoffprüfung 2011

Wolfgang Grellmann is director of the Polymer Service GmbH Merseburg, Germany, and holds a position as professor of Materials Diagnostics/Materials Testing at the Martin-Luther University Halle-Wittenberg, Germany. He received his diploma in Physics in 1974 and his PhD in Materials Science in 1978 from the Martin-Luther University Halle-Wittenberg working on the recording hardness testing of glasses and ceramics. In 1986 he finished his habilitation thesis dealing with the assessment of toughness behaviour of polymer materials using fracture mechanics parameters. His research interests include experimental methods of engineering fracture mechanics, deformation, and fracture behaviour of polymers and composites, hybrid methods in non-destructive materials testing, failure analysis, aging phenomena as well as biocompatible materials and medical implants.

Prof. Dr.-Ing. Beate Langer, was born in 1964 and studied Polymer Material Engineering at the Technical University Leuna-Merseburg, Germany from 1983 to 1988. Then she received her PhD at the Martin-Luther-University Halle-Wittenberg, Germany. Today she holds a position as professor of Plastic Engineering/Polymer Materials at the University of Applied Science Merseburg and is director of the Polymer Service GmbH Merseburg, Geusaer Straße, 06217 Merseburg, Germany.
