Abstract

The chapter starts with a discussion of the structural health monitoring (SHM) techniques for aerospace composites. This is followed by a presentation of the major sensor classes used in SHM practice with focus on advanced sensors such as optical fiber Bragg gratings (FBG) and piezoelectric wafer active sensors (PWAS). Electrical sensing methods for composites SHM are also discussed. The chapter expands the discussion on several tracks such as passive sensing SHM, active sensing SHM, local-area sensing with the electromechanical impedance spectroscopy (EMIS), active sensing SHM with electrical methods, direct methods ...
