Materials have been the primary element of the structural community from the existence of ceramics to the more durable and efficient polymers. The uniqueness of these materials stems from a necessity of a particular era. Because of the uniqueness of each material, the study of damage is of key interest in materials research. In conjunction with the essential materials, proper joining techniques are also fundamental in infrastructure; however, joints represent one of the greatest challenges in the design of structures. Current forms of joining include mechanical and adhesive, where adhesive bonding is preferred. However, no joint can be properly designed without adequate surface preparation. Proper methods for surface preparation and joining techniques will be reviewed for composite materials. This review will highlight some of the common approaches used to enhance the strength of the joint and, therefore, the structure itself.
