- Applications
Hexcel HexWeb® Rigicell™ honeycomb finds numerous uses as an energy absorption medium where large predetermined crush forces are requested to decelerate, restrain, and protect moving objects. Crush strokes of up to 65% are obtainable.
HexWeb® Rigicell™ is used in sandwich structures when high strength and rigidity are requested. In addition, it is used as a higher performance alternative to epoxy potting compounds, aluminum extrusion and machined aluminum details in honeycomb structures for fastener inserts, details and closeouts. For the same weight as epoxy potting compounds, HexWeb® Rigicell™ offers higher strength, lower manufacturing costs, better reliability, and higher skin to insert bond strength. HexWeb® Rigicell™ eliminates expensive fit up and edge voids between extrusion and low-density core. For the same strength, HexWeb® Rigicell™ weighs and costs less than machined details with undercuts and lightening holes.
HexWeb® Rigicell™ plugs are easily bonded in low-density core by wrapping them with a foaming core splice adhesive prior to insertion.
