Abstract

We develop a cassette-like peeling system for measuring fracture toughness of bonding assemblies composed of a soft film and a relatively rigid substrate. The system adopts a tensile load to drive the rotation of a cassette-like spool so as to peel the soft film, which facilitates its accommodation into universal testers. With this system, we maintain a self-similar fracture process zone and a stationary peeling front during peeling. Moreover, this simple-yet - versatile peeling configuration is naturally suitable for the evaluation of the delamination resistance of curved specimens, like those composite pipes manufactured by filament winding. A comprehensive validation is carried out by comparing the results of peeling a Kapton® tape and a hypereleastic film by using the developed peeling system and the conventional system. Featuring with the versatility and ease-to-use characteristic, the cassette-like peeling system has a potential to promote the next generation of peeling test standards.
