Abstract
Composite materials have been widely used for primary structures of aircraft, and a rapid diagnosis method for large composite structures like aircraft components is required. In this study, a new inspection method using a lightning protection shield (LPS) as a load sensor and its wiring is proposed. The proposed sensor identifies the coordinates of the impact point by the touchpad techniques. To verify the practicability of the proposed sensor, impact load tests were conducted with the proposed sensor of 360mmx225mm. The impacted position was identified within an error of 10.3mm.
