Research Into Alternative Aircraft Paint Stripping Methods

This paper documents research sponsored by the Federal Aviation Administration (FAA) to investigate the effects of alternative paint removal methods on aircraft structure. Industry data and specifications were identified that describe the effects and proper use of Plastic Media Blasting (PMB) on aircraft structures. A supplemental test program provided data on the specific substrate materials of interest to the FAA, anodized and alclad 2024-T3 aluminum in 0.032, 0.040, and 0.050-inch thicknesses. A technology survey of alternative paint removal methods was conducted, examining paint removal effectiveness, effect on the substrate, environmental impact, worker safety, and cost.
