ABSTRACT:
We reduce core crush in honeycomb sandwich structure by using a peripheral tiedown ply, generally in combination with a scrim-reinforced barrier film, between the composite laminate and the core along the panel chamfer to prevent slipping of the barrier film and outer laminates relative to the core during curing. We produce superior panels with lighter weights, improved mechanical properties, and more predictable structural performance.
