- Abstract
- To prevent burr and delamination defects that occur when drilling CFRP square pipes used in UAM aircraftfuselages, we developed an internal backup jig, with the burr area and delamination factors compared with acontrol group (with five holes drilled) and an experimental group. The experiments confirmed thatdelamination and burr occurrence reduced when the jig returned to the inside of the square pipe. Thedelamination factor decreased from 2.35 to 1.03, and the burr area factor decreased from 13.3% to 1.5% atthe exit of the drill hole after applying the developed internal backup jig, thus highlighting its effectivenessin suppressing defects inside difficult-to-repair square pipes.
