AVM 260IN - Advanced Composite Aircraft Repair II

4 Credits, 10 Contact Hours
1 Lecture Period 9 Lab Periods

Theory and application of composite and bonded metal structures utilized in aircraft construction. Includes repair methods selection, source documents, repair methods and design criteria, bonded metal repairs, tank and non-tank processing, priming, and environmental considerations. Also includes a heavy emphasis on repair performance utilizing the Structural Repair Manuals for composite monolithic and sandwich core, and bonded metal structures.

Prerequisite(s): AVM 130  
Information: IN is the integrated version of the course with the lecture and lab taught simultaneously.

Course Learning Outcomes
  1. Demonstrate Structural Repair Manual selection by determining Component identification and damage classification.
  2. Describe the function and use of source documents provided by aircraft manufacturers.
  3. Demonstrate repair methods including speed tape, resin sealing, potting, bolted doublers, wet layup at room temperature and elevated temperature, prepreg hot bonding, and edge and corner damage.
  4. Explain the history and purpose of bonded metal repairs.
  5. Demonstrate metal priming in preparation for metal bonding repair.
  6. Describe tank processing of bonded metal repairs.
  7. Differentiate non-tank processing of bonded metal repairs.
  8. Describe environmental considerations in the handling of composite and metal bonded materials.
