Abstract

L'invention concerne un dispositif et un procédé de tests en pelage, pour tester la résistance au pelage d'éprouvettes (40) formées chacune d'un support (42) et d'un adhésif (44), et comprenant - un bâti (60) comprenant des rouleaux (70, 74) d'axes parallèles destinés à maintenir en appui l'éprouvette (40) tout en la guidant en déplacement, - des moyens de traction (76, 78) reliés à des moyens d'accrochage (84), configurés pour entrainer le décollage de l'adhésif de la surface du support, - des moyens de mesure de la force (80) mise en œuvre par les moyens de traction pour tracter les moyens d'accrochage lors du pelage, - une éprouvette (40) de forme complexe, telle qu'issue d'une aube renforcée. Selon l'invention, les rouleaux de guidage (70) possèdent chacun une surface locale annulaire d'appui externe d'aspect linéaire, et l'éprouvette a été préparée spécialement pour faciliter le déroulement des tests.The invention relates to a device and a method for peel tests, for testing the peel resistance of test pieces (40) each formed of a support (42) and an adhesive (44), and comprising - a frame ( 60) comprising rollers (70, 74) of parallel axes intended to keep the test piece (40) in support while guiding it in movement, - traction means (76, 78) connected to hooking means ( 84), configured to cause the adhesive to peel off the surface of the support, - means for measuring the force (80) implemented by the traction means to pull the hooking means during peeling, - a specimen (40) of complex shape, such as coming from a reinforced blade. According to the invention, the guide rollers (70) each have an annular local external bearing surface of linear appearance, and the test piece has been specially prepared to facilitate the performance of the tests.
