DISTRIBUTED CURE MONITORING OF COMPOSITE AEROSPACE STRUCTURES

Distributed dielectric cure monitoring (D-DEA) is a new concept for the application of dielectric analysis (DEA) in manufacturing. Instead of a single expensive base instrument and many long extension cables, D-DEA uses multiple inexpensive instruments connected along a single RS-485 communications line. Distributed dielectric cure monitoring for the first time allows the use of DEA to monitor many locations in very large autoclaves such as those used for composite aerospace structures. Distributed dielectric cure monitoring also avoids the tangle of extension cables used for monitoring parts requiring multiple sensors, such as aircraft and spacecraft components.
