Dehnungsinduzierte Kristallisation in Naturkautschuk

5 Januar 2024

Prof. Dr.-Ing. habil. Alexander Lion und Prof. Dr.-Ing. habil. Michael Johlitz, Institut für Mechanik, Fakultät für Luft- und Raumfahrttechnik haben das Projekt „Experimentelle Untersuchung und Modellierung der dehnungsinduzierten Kristallisation in Naturkautschuk unter verschiedenen Alterungsbedingungen“ bei der Deutschen Forschungsgemeinschaft eingeworben.

Laufzeit: 01.01.2024 bis 31.12.2026

Förderung: DFG-Sachbeihilfe – Deutsche Forschungsgemeinschaft e. V. (DFG)

Strain-induced crystallisation (SIC) in natural rubber (NR) is considered to be the main source of its outstanding properties such as self-reinforcement and high tear resistance, especially when NR is further stiffened by nanoparticle fillers. For this reason, NR is often used in vehicle tires, vibration isolators, pipes and engine mounts. This fundamental project is not about examining, modeling and simulation of parts or structures, but of material properties. As SIC reduces the speed of crack propagation, the applications mentioned above serve only as a motivator for the project. The interdisciplinary SICX project has the following targets: further investigations of the kinetics of SIC on different scales, development of a three-dimensional model for the material behaviour of NR under SIC, understanding and modelling the impact of environmental conditions on issues.
