Drum peel test on sandwich specimen - Testing of composites
Universal testing machine inspekt blue 20 kN
Test methods and standards
- Testing of sandwich composites by means of drum peel test according to DIN EN 2243/3 and ASTM D 1781.
- These fiber-reinforced composite materials are used in the aviation industry in particular.
- The aim of the test is to determine the peel resistance of structural adhesives on honeycomb core composites.
- The test can be carried out at room temperature or other defined temperatures.
Test setup and procedure
- Testing system: Universal testing machine inspekt blue 20 kN.
- Accessories:
- Special roller peeling device for precise execution of the drum peel test.
- Vice grip for secure fixing of the specimen.
- Measuring principle:
- The separating force between the top layer and the core composite is determined using a peeling tool.
- The opposite side of the top layer is fixed to the vice grip and pulled at a defined speed of 25 mm/min.
- The resulting loads provide information about the adhesion properties of the adhesive bond.
Testing software and automation
- Control via the LabMaster testing software with the module for peel tests.
- Automatic recording and evaluation of load-displacement data to ensure reliable and reproducible test results.
- Integration of temperature chambers possible to test the material behavior under different climatic conditions.
Advantages and areas of application
- Precise and reproducible test results thanks to the standardized test setup.
- Optimum adaptation to different sandwich materials thanks to modular test configurations.
- Used in aviation, automotive industry and research to ensure the structural integrity of bonded joints.
- Can be extended with various grips and peeling fixtures to test different material combinations.
