COMPOSITE HONEYCOMB SANDWICH STRUCTURE

PROBLEM TO BE SOLVED: To provide a honeycomb sandwich panel having a barrier layer between a skin layer and a honeycomb core in order to inhibit the inflow of a resin to the honeycomb core. SOLUTION: The composite honeycomb sandwich structure comprises: (a) a honeycomb core 106 having core cells; (b...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a honeycomb sandwich panel having a barrier layer between a skin layer and a honeycomb core in order to inhibit the inflow of a resin to the honeycomb core. SOLUTION: The composite honeycomb sandwich structure comprises: (a) a honeycomb core 106 having core cells; (b) at least one composite laminate plate 102 having a ply of a matrix resin reinforced with fibers adhered to the core; (c) a film barrier layer 110 between the laminate plate and the core which combines the laminate plate 102 and the core 106 and eliminates the flow of a resin from the laminate to the core; and (d) a film adhesive 112 between the barrier layer and the core having a supporting scrim for eliminating the resin stream into the core cell 106 or the slack of the barrier film 110 to the core cell.
