Application
- A climbing drum test is a typical peel testing method used to determine the de-lamination characteristics of adhesives used to bond different materials together. This test covers the determination of the peel resistance of adhesive bonds between a relatively flexible adherent and the relatively flexible facing of a sandwich structure and its core.
Purpose
- When the adhesive used is relatively brittle, the peel resistance can often indicate the degree of cure, or to cause a material to bond by permanently cross-linking its molecules. Adhesives cure as they solidify, that is, higher values than normally realized may indicate an incomplete cure. The test involves a measurement to determine the strength of a laminate's bond to a substrate material. It is equal to the tensile load applied divided by the sample width multiplied by the sample's thickness.
