Article Abstract:

Although there are some disadvantages in using mechanical fasteners to join composites, such as stress concentrations, they are still the most appropriate method. Bonded joints require pre bonding treatment and if exposed to moist atmospheres they may have their strength reduced. In designing mechanicall fastened jonts in composites, holes of acceptable quality should be produced, stress concentation around the holes should be minimsed and adequate constraints to the laminate should be provided.
