ASTM D1781 Climbing Drum Peel Testing

In order to peel the flexible material from the rigid backing material and accurately measure the peel strength, a special device called a climbing drum peel fixture shown is used. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Send us a request Wilton UK: Direct comparison of different adhesives or processes can only be made when specimen design and test conditions are identical. From climbing drum peel results the following calculations can be made: Standards can be obtained from appropriate standard authorities.

Samples need to be thick enough not to bend during test. The adhesive used for the sandwich panel construction is critical to ensure structural integrity. Formally confirming that your products and services meet all trusted external and internal standards.

For example it measures the peel resistance between:. Certification Formally confirming that your products and services meet all trusted external and internal d1718. When a relatively brittle adhesive is used, the peel resistance can often give an indication of the degree of cure, that is, higher values than normally realized may indicate an incomplete cure.

Historical Version s – view previous versions of standard Translated Version s: The corresponding amount of crosshead movement is dependent on the geometry of the climbing drum peel fixture.

Climbing Drum Peel Fixture mm wide eccentric roller grip. The grips f1781 a Universal Test Machine are initiated at a specified grip separation significant enough to roll the drum upward.

This test method is used to compare adhesion between flexible and rigid adherends, or between flexible facing of a sandwich structure and its core. Testing can be complicated due to high adhesion strength and the dimensional rigidity of the core section, and the fact that the facing panels are not completely flexible.
