Abstract
Repairs to the 7075-T6 aluminum alloy composite structure of the aircraft flap trailling edge undergoing detachments at airlines around the world. Some particular factors of this structure intensify the probability of a detachment in the region - a high temperature of operation of the component, low quality repairs caused by human factors and the application of an inefficient surface preparation method. The purpose of this study is to list which method of surface preparation is the most suitable for repairs to the component, in order to increase the durability of repairs in the region. Tensile tests were carried out, standardized by the ASTM D 1002 standard, with the aim of comparing the maximum rupture force and the type of proof failure treated using Alodine 1200 and Boegel compounds, with or without the application of a bonding primer. After these tests, the nal conclusion is the effectiveness of the treatment using the Boegel compound without applying the bonding primer. This method has greater eciency among those tested and greater dimensions of adhesion related to cohesive type fractures.
