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.
