Ultrasonic C-scan as an affordable technique to quantitatively assess damages in laminate composite materials
Abstract
Ultrasonic C-scanning is presently noted to offer a relatively low cost method for the evaluation of composite materials after exposure to potentially damaging conditions. The use of a scalable 'damage parameter' is shown to be especially useful in the case of C-scans of relatively thin laminate coupons with only minor suspected damage. The numerical data obtained via ultrasonic C-scanning can be normalized and reduced through computer analysis methods so that damage progression can be quantified.
