Reducing repair dimension with variable scarf angles

The increase in composites usage for primary and secondary structural components demands advanced repair techniques such as doubler, multi-step, and scarf to restore a damaged structure to its original design capability. Currently, most scarf repairs employ a straight taper at a typical ratio ranging between 1:20 to 1:60 to attain the original design strength. This paper aims to present a new method for reducing the footprint of scarf repairs by...
