Inspection of Composite Components

Trends In Aerospace Composite Manufacturing

Increased use of large, unitized structures
Improved designs and processing required
Large parts are too expensive to be rejected
Careful evaluation (and possible repair) is required
Current inspection techniques (water-based, laser-based) are not effective in a lean
   environment


Ideal system

Agile (robot-mounted)
High sensitivity
Effective validation for large structures
Leads to lower system cost
Move inspection closer to manufacturing operations
   o On tool
   o Uncured state
