Abstract

A coupon suitable for peeling tests, derived from a vane and including: (i) a portion of blade that comprises an intrados surface, an extrados surface and a leading edge and/or trailing edge and (ii) a vane reinforcement that covers and is glued to at least a part of the intrados surface, a part of the extrados surface and which extends beyond the leading and/or trailing edge. The reinforcement is split over the entire length of the leading edge and/or trailing edge such that the reinforcement is separated into two plates separate from one another and facing each other on either side of the slit beyond the leading and/or trailing edge. Furthermore, at least one of the plates furthermore comprises, beyond the leading and/or trailing edge, notches configured to provide a hold to this same plate.
