PA UT (PAUT): Glass Fiber

Inspection of the glass fiber made composite parts for the debonding, porosity, and other structural defects is performed by the ISONIC 3510, ISONIC 2010, and ISONIC 2009 UPA Scope instruments with use of the linear array probes equipped with the solid delay line or the rolling linear array probes with the soft contact surface protector and water-filled delay line. The standard 0-deg linear scan (B-Scan) mode combined with the non-linear acoustic based signal processing provides the cross-sectional coverage and clear imaging for the entire thickness of the material. The line scanning either encoded or time-based provide the volume coverage along the scanning line within entire width of the PA probe



The following features are provided:
  • Scanning Pattern (Scan Plan) Design
  • Intuitive Image Guided PA Pulser Receiver with Beam Forming View
  • True-To-Geometry 0-deg Cross-Sectional Coverage of the material and line scanning along the part either encoded or time based
  • "On-the-fly" True-To-Geometry Material Overlay Volume Corrected Imaging:
    • Cross Sectional Slices
    • Top (C-Scan) View
    • Side View
    • End View
    • 3D View
      •
  • DAC / TCG Data / Image Normalization
  • Independent on TCG Angle Gain Per Focal Law Correction
  • 100% Raw Data Capturing
  • Automatic Defects Alarming Upon C-Scan Acquisition Completed
  • Automatic Creation of Editable Defects List
  • Comprehensive Postrpocessing Toolkit Including:
    • Recovery and Evaluation of the Captured A-Scans from the Recorded Cross Sectional Views and C-Scans
    • Recovery of the Cross Sectional Views from the Recorded C-Scans
    • Converting Recorded C-Scans or their Segments into 3D Images
    • Off-Line Gain Manipulation
    • Off-Line DAC Normalization of the Recorded Images / DAC Evaluation
    • Numerous Filtering / Reject Options ( by Geometry / Position / By Amplitude db-toDAC / etc ) and Regeneration of the Corresponding of Editable Defects List and Storing it into a Separate FIle
    • Defects Sizing
    • Automatic creating of inspection reports - hard copy / PDF File

The movie below illustrates the scanning of GFRP panel calibration block with flat bottom holes, the operator's observations and the evelauation at the postprocessing stage



The videos below illustrate 0-deg compression wave scaning of the GFRP panel using the water filled rolling probe with soft silicon tire and linear array probe with solid delay line





The video below illustrates inspection of the GFRP made component of aircraft frame



Another typical case related to the inspection of GFRP panel made through the bonding between two plates (for example – composite repair) has been illustrated by the video below, which shows the ability of detecting de-bonding between the plates and internal defects in both plates as well. The internal defects are detectable through the scanning above the plate carrying them as well as from the opposite side



The short movies below illustrate detection of the lamination in the GFRP calibration block use of the ISONIC 3510, ISONIC 2010, and ISONIC 2009 UPA Scope instruments
