There will be some tests that require using an adhesive rather than a mechanical fastener to combine two or more things together. Some joints will be fixated using an adhesive but need to follow a strict protocol when applying it, and for it to take full effectiveness. The two joints that we are concerned about in consideration of Adhesive Testing are the Butt Joints and the Lap Shear Adhesion.
Note: The material consists of a 6oz twill carbon fiber (2 layers), 9.5mm divinycell foam core and another 2 layers of carbon fiber.
Figure below shows a rough sketch on what a single lap shear adhesion looks like. (One material is stacked onto another)
Figure below shows a rough sketch on what a butt joint looks like: (The adhesive is placed on both faces of the material)
