Low Frequency PA Inspection
The inspection of heavy composites thicker than 50 mm (2 inches) causes significant limitations for conventional phased array probes.
A Solution for Very Thick Composites and Castings
Conventional phased array (PA) probes have significant limitations when inspecting heavy composites thicker than 50 mm (2 inches). Even traditional PA probes at 2.0 MHz frequency are not the appropriate solution for such high signal attenuation and long sound path. The 0.5 and 1.0 MHz PA probes are available that can successfully provide C-scan mapping over large glass fibre surfaces. Furthermore, lamination defects can be identified in aluminium slabs.

Frequency recommendation according to the GFRP thickness:
1.0 MHz probe: T= 30 to 200 mm. Better resolution, main solution for glass fibre reinforced plastic
0.5 MHz probe: T< 50 to 500 mm. Very high attenuation material (Such as low-density polyethylene)
