Abstract

A mechanically fastened joint in Carbon Fiber Reinforced Plastic (CFRP) laminates is necessary due to its advantages in inspection, replacement and reliability. The mechanical joint should be designed to make the bearing failure mode occur because the strength is high and the joint fails noncatastrophically. This study detailed the bearing damage evolution of the pinned joints for both [0/±45/90]3S and [90/±45/0] 3S CFRP laminates and its difference between static and fatigue loading is discussed. In static tests all 0° layers have kink at the maximum loading and the kink is a trigger to the final failure. On the other hand, under fatigue loading the final damages start mostly from collapse at the loaded surface edge. It is also found that delamination of fatigue case is longer than that of static and that [90/±45/0]3S presents higher strength and shorter delamination than [0/±45/90]3S in both static and fatigue cases.
