PAA-SFH has been developed to enhance the properties of standard aluminum honeycomb against the corrosion. The enhanced corrosion protection of PAA-SFH can provide a potential to reduce a life cycle cost or/and to reduce manufacturing cost occurred for additional processes to improve corrosion protection and durability of the standard aluminum honeycomb. For this reason, PAA-SFH will be an alternative for the standard aluminum honeycomb being used for the bonded assemblies of aircrafts.
