Non Destructive Testing by Acoustic Emission & Ultrasonics : Composite Structures & Materials

Our knowledge at your disposal
Euro Physical Acoustics proposes three non-destructive testing solutions to characterize composite material:
Acoustic Emission (AT):			allows detecting, locating and identifing growing damage under mechanical and/or thermal loadings.
Ultrasound (UT):			allows characterizing small size damage or design defaults.
Acousto-Ultrasound (AU):			allows detecting and locating damage within thick and /or absorbent composite materials.

	Static /Dynamic Method	Global / Local Method	Real Time	Damage Type	Absorbent material
AT	Dynamic (structural loading)	Global	Yes	Delamination, fiber cracking, matrix cracking, fretting, disbonding,...	+
UT	Static	Local	No	Discontinuity (material interfaces, holes, ...) delamination, disbonding, porosity	-
AU	Static	Global / Local	No	Discontinuity (material interfaces, holes, ...) delamination, disbonding, porosity	++
Linear localisation using Acoustic Emission			Ultrasound scan (Immersion system)
Acousto-Ultrasound scan (dry couplant)
