The Adhesive-Bonded Surface Durability Test (Wedge Test). This is a Mode I crack opening test used primarily in aerospace to evaluate surface preparation. A wedge is driven into the bond line, and the assembly is placed in a humidity chamber. The engineering metric is the Crack Growth over time. MTO provides specialized Wedge Driving jigs and high-magnification optical measurement tools. This is a critical lead for companies moving from mechanical fasteners to structural bonding, as it isolates the effect of environmental moisture on the adhesive-to-substrate interface.
