Description
Adhesive joints are presently widely used in both industry and everyday life applications. Adhesives popularity stems from the possibility to create joints without breaking the material structure, the possibility to create joints flexible to a certain extent, and the high aesthetics of the joints. Proper adhesive joint design requires consideration of both the properties of the surfaces to be joined and the adhesive, as well as the external factors influencing the manufacturing process. Surface modification processes, including physical (mechanical) and chemical modification, play a key role in ensuring the desired adhesion of the adhesive to the materials. Physical surface modification is recommended for practically all materials and is observed to have a beneficial effect on the strength of the joints regardless of the chemical nature of the material, while the choice of chemical modification method is strictly dependent on the type of materials being joined. In the talk I will provide a brief introduction to adhesive joints technoly and present an example of how different level of roughening affects the joint strength in conducted lap shear strength test.
