Facesheet Consolidation During Autoclave Co-Cure of Honeycomb Core Sandwich Structures

 

The co-cure of honeycomb core sandwich structures involves concurrent facesheet consolidation, adhesive bond-line formation, and core pressure evolution. Interactions between these phenome-na are complex and can influence manufacturing efficiency and part quality. Facesheet consolida-tion during autoclave co-cure was investigated. Two prepregs designed for primary aerostructures were characterized to assess their baseline microstructural evolution. Then, skin-adhesive-core assemblies were co-cured within a fixture capable of accurate autoclave, bag, and core pressure control, and of in-situ measurement and visualization. Several pressure conditions were studied, and bagging conditions were varied to promote or inhibit air evacuation from the facesheet. Re-sults indicated that consolidation was potentially affected by prepreg microstructure, resin bleed into core cells, and processing pressure, and that variability between and within facesheets was high.
