Objectives:
-
To develop nondestructive testing to detect disbonds in composite repairs
- To develop analytical
models to assess degradation of strength and life of repaired parts
-
To test and verify the results
Approach:
- Identify types
and procedures of composite repairs
- Generate/acquire
samples with and without disbonds
- Perform NDE in cooperation with ISU-CASR
- Perform destructive
measurement of damage to map damage size, mechanical properties, fatigue
life and residual strength and correlate to NDE
- Develop FEM for
stress and fracture mechanics analysis to assess the severity of the
disbond and correlate to measured strength and life of repairs
The quality assurance of repairs made on composite components and the predictability of the remaining service life of the repaired ports is essential to their continued airworthness.
Products:
- Engineering data
for composite repairs
