Fraunhofer Institute for Microstructure of Materials and Systems IMWSThe drum peel test is an established test method for determining the adhesive strength between the top layer and core material of sandwich composites. This test quantifies the peel force required and thus the peel resistance of the adhesive layer between the cover layers and the core material of a sandwich composite. This is particularly relevant for quality assurance in aerospace, automotive engineering, and wind energy technology, where sandwich structures are widely used due to their low weight and high rigidity.
In the test, a sample strip is clamped into a testing machine so that the cover layers are peeled away from the core material by a rotating drum. The force applied is continuously measured and recorded to determine the peel resistance. The results provide important information about the processing quality and long-term behavior of the composite materials under load.
