Selective Atmospheric Plasma Coating Removal (APCR) for Composite Substrates
Abstract
This study investigates the application of Atmospheric Plasma Coating Removal (APCR) on composite materials prevalent in aerospace and defense assets. The technical objective was to demonstrate the efficacy of APCR on a standard aerospace coating stack and to investigate the effects of APCR on a graphite/epoxy composite substrate. Tests were completed to fulfill these objectives, including Multi-Scan Optical Microscopy, Scanning Electron Microscopy/Energy Dispersive Spectroscopy (SEM/EDS), Fourier Transform Infrared Spectroscopy (FTIR), Ultrasonic C-Scans, Short Beam Shear, Differential Scanning Calorimetry (DSC), and recoating was evaluated by pull-off coating adhesion strength testing. Results indicated no adverse effects on carbon fiber composites after APCR. However, limitations in existing testing methods highlight the need for refined approaches, including advanced mechanical testing and detailed adhesion assessments. Continued research is essential to ensure APCR's efficacy and safety, guiding its implementation in practical aerospace and defense scenarios.
