The specimens tested are double butt joints assembled with sealant on mating surfaces (sealant is a corrosion inhibitive). The Hi-Loks are with aluminium collars installed with clearance . Fatigue test (with sinusoidal loads, R=0.1) shown a terrible behaviour of sealed specimens. The sealant...
I'm studying the fatigue behaviour of sealed rivet joint. I’m using Aluminium 7xxx, polysulfide sealant and Hi-Lok rivets. Maybe somebody can explain what is the surface treatment prior to seal the rivet joint?
What is the fatigue behaviour of sealed rivet joint?
Thanks rb1957…
I know the different behaviour of fatigue properties(a different profile of a collar), but I don’t understand the different fit interference about Hi-Lok vs Hi-Lite and how much.
