Hexcel® HexWeb® CFC™-20-1/8-5.0 Composite Flooring Honeycomb Core (discontinued **)
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoset; Aramid
Material Notes:	Designation: Material-Cell Size-Density. Hexweb® CFC™-20 is manufactured from NOMEX aramid fiber sheets. A thermosetting adhesive is used to bond these sheets at the nodes and, after expanding to the hexagonal configuration, the block is dipped in phenolic resin. After curing the resin, slices are cut to the desired thickness. Features: Specifically designed for aircraft flooring applications; Superior properties and performance over balsa and foam core materials; Proven durability in extensive flooring tests; Significant weight advantage over balsa and foam core materials; Exceeds all FAA safety requirements; Excellent property retention at 350°F; Moisture and fungus resistant. Applications: Hexweb® CFC™-20 honeycomb core was specifically developed to provide a tough, lightweight core material for use in aircraft flooring systems. A range of product densities are available to fit a wide variety of loading requirements. The core material when bonded to metallic or nonmetallic facings provides a flooring panel sheet which may be cut or contoured to fit any aircraft flooring module.
