Axial Fatigue Test Fixtures

Graft Stitch Fatigue Testing 

Graft materials require stitching to either join them to stent structures or to create seams in the material. The stitching is often the weak link in the graft envelope and the fatigue resistance of the stitching needs to be characterized.

The fixture shown is used to characterize the fatigue resistance of stitched graft material subjected to repeated loading. The fixture shown is configured for multiple specimens but it can also be configured for a single specimen.

MDT has considerable expertise performing fatigue testing on fabric stitching. Contact us with your specific test requirements and we will provide an estimate for performing axial fatigue testing on your graft stitching.
