摘要： The invention relates to a device and a method for peeling tests, for testing the resistance to peeling of coupons (40) each formed of a substrate (42) and an adhesive (44), and comprising a frame (60) with rollers (70, 74) having parallel axes for holding the coupon (40) in abutment whilst guiding its displacement, traction means (76, 78) connected to attachment means (84) which are designed to bring about the lifting of the adhesive off the substrate surface, means (80) of measuring the force exerted by the traction means for pulling the attachment means during the peeling stage, and a complex-shape coupon (40), such as a coupon taken from a reinforced vane. According to the invention, at least one of the rollers (70. 74) can be adjusted in translation relative to the other rollers, and the coupon is prepared especially to facilitate the tests.

摘要： The invention relates to a coupon (40) which can be suitable for peeling tests and is taken from a vane, the coupon comprising: a blade portion (42) which comprises a pressure-side surface (42a), a suction-side surface (42b), and a leading and/or trailing edge (46), and a vane reinforcement (44) which covers and adheres to at least part of the pressure-side surface, a part of the suction-side surface, and extends beyond the leading and/or trailing edge. According to the invention, the reinforcement (44) is split over the entire length of the leading and/or trailing edge (46), such that the reinforcement is separated into two plates (44a, 44b) which are distinct from and opposite one another on either side of the slit (48) beyond the leading and/or trailing edge. In addition, at least one of the plates has, beyond the leading and/or trailing edge, attachment means (50, 52) providing this part with a hold.
