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
Global / Local
Damage Type Absorbent
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 ++
