Plasma Injection and In-Line Quantitative Gas Analysis for Real Time Monitoring ofInternal Delamination Contamination Removal and Surface Modification
Abstract
This proposal requests equipment which would greatly enhance outcomes of the current ONRsupportedproject at UC San Diego: Quantitative Injection Repair Characterization and StrengthRestoration, Award Number N00014-19-1-2164. The overarching objective of this currentproject is to provide ability to quantitatively assess injection repair of delaminations, with theultimate goal being to allow this method to be relied upon as one returning strength to thecomponent. Two major instruments are proposed for purchase under the DURIP program: 1)Surfx Atmospheric Plasma System Atomflo 500, and 2) Hiden QGA Quantitative Gas Analyzer,type 305110; including Hiden HAL 201 RC mass spectrometer with Faraday/Multiplier detector.A critical aspect of successful adhesive bonding is surface preparation. This includes insuringthat contaminants are removed, and also imparting modification of the surface so that it isamenable to forming strong bonds with the adhesive or injection resin. The requestedinstruments enable the UC San Diego team to develop novel methods which address the surfacepreparation of internal delamination surfaces (i.e., not directly accessible) prior to injectionrepair.Furthermore, dedicated equipment located at UC San Diego, and not using equipmentlocated as part of a shop production environment, allows these systems to be 100% dedicated tothe projects use, and also allows custom modifications to the system (impossible when usingproduction-dedicated equipment). In the long-term, it is anticipated the findings of the currentinjection repair project would involve tech transfer to Navair, with need for parametricoptimization for various composite material types and configurations, contaminant sources, etc.The proximity of UC San Diego with FRCSW enables an ideal partnership to permit such nonstandardsystem optimization studies with lab-dedicated equipment not devoted to productionline environment.
