Expert Commentary
The Climbing Drum Peel Test for Adhesives. This is a specialized aerospace test for sandwich panel skins. It involves a drum that climbs up the specimen, peeling the skin from the core. The engineering complexity is the Torque calculation. The weight of the drum must be accounted for in the force measurement. MTO provides the calibrated Climbing Drum fixture and a specific software module that subtracts the drum’s mass and the force required to bend the skin, yielding the True Peel Torque. This is the gold standard for verifying the bond integrity of honeycomb structures.
