Mechanism of Fungal Degradation in Military Aircraft Coatings

Abstract

The overall goal of the project was to elucidate various mechanisms that mold fungi utilize to degrade various coating systems used on the surfaces of military aircraft/hardware. The technical objective was to investigate the mechanisms of mold fungi degradation to coatings on aircraft structures caused by mechanical and/or chemical penetration. These objectives were fulfilled by undertaking tasks, including A) testing of mold fungi on various coating materials that are used for coating systems (topcoat and primers); B) investigating direct penetration of mold fungi to topcoat and primers and associated physical changes leveraging atomic force microscopy (AFM) and laser scanning confocal microscopy, and C) utilizing infrared (IR) imaging system for the chemical composition of coating materials and its application for chemicals produced by mold fungi and during colonization to coating material along with effects of antifungal and antimicrobial peptides on mold fungi.
