Quasi-static behaviour of composite joints with countersunk composite and metal fasteners

摘要

An experimental study of the quasi-static behaviour of composite joints has been carried out. Composite plates were joined by six fasteners of three different types: composite, titanium Torque-set, and titanium Huck-comp. Specimens were quasi-statically tested to obtain results of the joint tensile and compressive strength. Strain gauge and extensometer measurements were used to investigate the static beaviour of the joints. Strain gauge measurement were carried out to analyse strain distribution and load transfer between bolt rows. Extensometer measurements were done in order to observe bolt-movement behaviour. Generally, composite joints with titanium fasteners have a higher quasi-static strength than that with composite fasteners.
