Strength reinforced plastic peel ply sandwich peel torque strength, puU. 

Honeycomb Peel A conventional thin-skinned honeycomb sandwich panel is tested in peel using the so-called climbing drum peel rig (Fig. 50). Applying a measurable torque to the drum forces it to climb the specimen and, hence, peel off the bonded skin enough specimens are tested to be able to assess the adhesive bond to both top and bottom skins in the sandwich.
