Module 15: Practical Assessment and Logbook Evaluation

  • Describe the differences between prepreg repairs, wet lay-up repairs, and bolted repairs.

 

Module 16: Practical Assessment and Logbook Evaluation

  • List the various types of Non-Destructive Inspection (NDI) techniques and their limitations during manufacture and repair of composite structures.
  • Perform a visual and tap test inspection on a sandwich constructed part and correctly map the damaged area.
