Study of step-lap repairs from elementary coupons to structural evaluators
Abstract : Two scales for the study of a step-lap repair are presented. To perform the repair machining, an Abrasive Water Jet process (AWJ) is used in order to obtain a step-lap shape. A single step-lap machining is performed to create some tensile coupons in order to identify the shear behavior of the adhesive. Tensile tests emphasize difficulties in obtaining desired stress state in the desired location. A repair evaluator is created to study the behaviour of a composite repair at the scale of a real structural part. The evaluator presents a double step-lap shape machined using AWJ. By the use of the Multi-instrumented Technological Evaluator (MITE) toolbox and benefiting from the flexible multiaxial loading offered by its experimental part, the desired stress state in the repaired zone can be obtained. Results of the structural tests are presented and discussed.
