Project No. SR-1464Marine Composites NDE

• Purpose of Project

• Develop state-of-the-art review of relevant
  large-scale composites NDE technology
• Evaluate the efficacy of candidate advanced NDE
  to detect common defects in marine composite
  structures
• Provide assessment of Best Practice NDE methods
• Develop web site and final report to present
  project results and serve as a useful reference

Project No. SR-1464Marine Composites NDE

• Future Work

• Prepare test panels with know defects
• Evaluate test panels with candidate NDE devices
  and document results
• Document case studies of advanced NDE use with
  marine composites in the field
• Develop web site and final report to present
  project results and serve as a useful reference

Project No. SR-1464Marine Composites NDE

• Preliminary Conclusions

• The primary advanced NDE techniques suitable for
  marine composite construction include
• - Ultrasonic testing- Thermography- Laser
  Shearography
• Operator training is essential for the correct
  interpretation of results
• Baseline data with good laminates and laminates
  with known defects improve the confidence in NDE
  results
