Mechanical testing

In group “Assessment of Composite Systems” the focus is on evaluating the use of polymer-based fibre composites in highly stressed lightweight structures and components. Experimental and numerical methods are used to characterise the mechanical behaviour both under application-related and process-related loads, which are adapted to the special requirements of fibre composites. One focus of the work is the material-mechanical characterisation of materials by means of destructive testing and the evaluation of manufacturing defects and damage (e.g. delamination) with fracture-mechanical methods.

Selected services:

• Determination of mechanical and physical material properties of fibre composites and sandwich core materials
• Development and implementation of structural and component tests (e.g. sandwich shells)
• Evaluation of damage tolerance of fibre composite materials and structures with fracture mechanics methods (e.g. for lifetime prediction of damaged structures)
• Analysis of service life and ageing behaviour (e.g. under environmental influences)
