To verify the mechanical resistance of these pipes, we prepared standardized specimens in longitudinal, transverse directions and CT and DCB types. In order to perform tensile tests on the MTS 810 tensile (or fatigue) machine, flat specimens are widely used, but transversely cut specimens and CT and DCB types are not widely used. The main objective of this scientific paper is the innovation of two steel grips A and B, which will allow to fix specimens inside the jaws of tensile (or fatigue) machines in order to obtain reproducible tests. This docking and alignment device transform the non-limiting tensile (or fatigue) machine, with the rapid adaptation of the tensile machine jaws capable of clamping specimens of complex geometric shapes.enCompositesTensile testFatigue machineDocking and alignmentSteel gripsMechanical realizationArticle
