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.
