ABSTRACT:
A method, in which a damaged site of a composite material structure, for example a wing skin on an aircraft, is repaired, includes the steps of repairing the damaged site with repair material, including adhesive, and at the same time bonding a test fixture, for example a button, at a test site next to the repair, by means of material that is the same as the repair material. The conditions to which the damaged site and the test site are subjected are substantially the same. After repair, the strength of the repair bond may be indirectly assessed by applying a torque to the test fixture, so as to assess the bond strength of the test fixture to the structure.
