1 Process Fragility in the Manufacture of Kevlar Wing Root Panels James CurranProcess Fragility in the Manufacture of Kevlar Wing Root PanelsLocation of wing root panel2mComplex curvatureKevlarSandwich panelGeometrical tolerancesFoiling cureIncreased production rate
2 Plan to double production rate Roll-out in ToulouseIncreasing scrap rateNDT (ultrasonic, X-ray, geometry)RED panels further down production lineUnconventionalNo destructive analysisProduction item (no interference, limited changes)
9 Solutions:New adhesive lay-upUse of a bleed pack for all consolidation operationsCore moisture controlCore trimmingCore filler controlKevlar moisture managementPerforated adhesiveSelf-adhesive foil / elimination of separate foiling cureNew tooling
