CORE AND STRUCTURAL COORDINATION / FIELD NOTE 09
Peel Strength and Flatwise Tension for Honeycomb Panels
Peel and flatwise tension apply different loading to a sandwich specimen. The reported values cannot be substituted for one another, and the failure location can tell you whether the bond, core or facing governed the result.
What to check on your project
Request the test method, units, specimen build-up and failure description with any reported number. Put results in separate comparison columns and let the specifier determine which evidence the project requires.
