Health Monitoring of Composite Repairs of Aircraft Structures
Original language description
The work focuses on aircraft structures and their parts which are designed using the damage tolerance approach. The main goal is design, verification, monitoring and certification process of fatigue crack repairs of the selected critical places on the Czech light combat jet L-159A. The repairs were carried out using carbon/epoxy composite straps and patches and cold-setting glue SW 9323. A new type of repair was developed and tested. It applied a boron/epoxy composite and FM 73 glue system with the gritblast/silane surface preparation. The aim of the tests was to prove better characteristics of the repair with the use of boron double-sided patch in comparison to the carbon repair as identified by fatigue testing. Possibility of application of the health monitoring methods is discussed here, especially the acoustic emission method and application of strain gauges and optical fibers with Bragg grating for the detection of strains in monitored or repaired locations.
