Abstract
The behaviour of a proprietary composite fastener bonded to a chopped strand mat/polyester resin laminate has been examined. Fasteners adhesively bonded with a two-part epoxy and a one-part cyanoacrylate adhesive were evaluated under both static and fatigue loading conditions and the results compared with similar data obtained with fasteners directly bonded into laminates. Under static loading and low cycle fatigue loading conditions, the bonded-in system gave a superior performance. At approaching 10 6 cycles the fatigue performance of each system was similar. The results for the adhesively bonded fasteners were shown to be sensitive to surface preparation techniques, whilst the performance of the bonded-in fasteners was improved by design modification of the fastener.
