Technical description

Main functions

The peel tester is used to continuously measure the adhesion energies of thermoplastic laminates in order to test and optimise the bonding process. The principle of winding and gluing a composite tape is a technology that is increasingly used in the industrial sector, as it offers better productivity. In order to optimise the quality of the bonding between the layers of the composite and certain physical parameters such as pressure, temperature or heat transfer, LF Technologies has developed a continuous peeling bench. This highly innovative system offers a high degree of accuracy in analysing interlaminar adhesion and debonding force. The machine can be directly installed in the production workshop in order to evaluate the adhesion parameters of thermoplastic composites in real time.

Operating mode

The continuous peel bench unwinds the composite strips by means of a speed compensated drum while the composite sample is held in rotation by a second drum which is also torque controlled. The peel angle is set by the operator and is servo-controlled to prevent the carbon fibres from breaking and thus allow continuous peeling. The higher the resisting torque, the more tangential the unwinding, and vice versa.
