Main functionsThe peel test bench enables continuous measures of the adhesive energy of thermoplastic laminated composites in order to test and optimize the bonding process.The principle of winding and bonding a composite strip is a technology increasingly used in the industrial sector because of its better productivity.In order to optimize the bonding performance between the layers of the composite and certain physical parameters such as pressure, temperature or heat transfer, LF Technologies has developed a continuous peel test bench. This highly innovative system offers a high degree of precision in the analysis of interlaminar adhesion and peel force.The machine can be directly installed in the production workshop in order to asses in real time the adhesion parameters of the thermoplastic composites. Operating modeThe continuous peel test bench unrolls the composite bands through a speed-compensated drum while the composite sample is held in rotation by a second drum whose torque is also controlled.The peel angle is user-set and servo-controlled to prevent carbon fibers from breaking and thus allowing continuous peel. The higher the resistive torque, the more tangential the unwinding, and vice versa.
