Characterization, Modeling, and Accelerating Emulation of Aircraft Coating Exposure and Degradation
A discussion will be given summarizing the measurement method and modeling studies of aircraft coating exposure and degradation in various environments. The lifetime prediction techniques that we have developed at NDSU from these measurement methods and modeling will be given. Current studies on the use of embedded electrodes and room temperature ionic liquids (RTIL’s) will be described as well as the new results on a more complete description of the wetting and drying processes in organic coatings that use of these materials allow. Prof. Tallman will summarize the NDSU studies of local damage protection mechanisms in aircraft primers using scanning electrochemical techniques, and Prof. Croll will discuss damage measurement and modeling of the behavior of aircraft topcoats in real and accelerated exposure. A discussion of recent developments in accelerated test protocols will follow, including exposure data from Simulated Aircraft Structures (SAS’s) in laboratory and Florida exterior exposure. Future work in this area will be described, including the integration of nano-, micro- and global- scale measurements and models for the increased understanding of coating systems for aircraft from substrate to topcoat.
