A portable field-application
nondestructive system for the inspection of multi-layer
compositesections based on oblique-incidence, low-frequency
Acousto-Ultrasonics (AU) has recently been developed
byPhysical Acoustics Corporation (PAC). This development was
the result of an SBIR (Small Business InnovativeResearch)
project sponsored by The Lightweight Structures Team at
TARDEC (Tank Automotive Research,Development and Engineering
Center). Although developed for the particular purpose of
inspecting multi-functional composite armor plates, PAC has
used this field inspection system in the evaluation of many
criticalcomposite structures. Some of these components
include Fiber-Reinforced Polymer “wraps” around
concretestructures, graphite-epoxy, foam-core composite
centrifugal arms for simulators, and type III Navy diving
bottles.
