#### 5.2.1 Summary of Suitability of Common Bonded Joint Types

Table 17 summarises the main characteristics of common joints. In particular, the following are analysed:

Self-alignment: The ability of the joint to arrange itself in the best position for bonding. Some joints are able to find and maintain the correct position on their own, while others require jigs or external fixturing to maintain the correct position during the bonding process.

Bond area: The total area available for bonding; the greater the area, the higher the joint strength.

Stress distribution: Depending on the type of joint, there will be a different distribution of stresses depending on the type of stress it must resist.
