The increased use of composite materials in aircraft structure has necessitated the development of new innovative fastening systems where assembly requires the use of mechanical fasteners. Fundamental differences in the behavior of composite assemblies vs. metallic assemblies required new strategies; fasteners have been developed to address lightning strike issues, reduced bearing strength of composite, the use of clearance fit holes and the need for increased automation. This paper will summarize how designers and manufacturers can achieve fastener installation rates in composite material equivalent to installation rates in metallic materials while ensuring the integrity of the composite material is not compromised.
