Material Notes:
Designation: Material/Cell Size (cells per lineal foot in W direction)-DensityHexcel manufactures two types of nonmetallic reinforced plastic HexWeb Flex-Core: HexWeb HRP - Fiberglass cloth reinforced with a high temperature phenolic resin. This product provides good retention of strength for temperatures up to 350°F.HexWeb HRH-10 - NOMEX aramid paper reinforced with a high temperature phenolic resin. This product provides good retention of strength for temperatures up to 300°F.Features: Specifically designed for formability; Retains mechanical properties in the curved condition; Offers cost savings for curved panels.Applications: The HexWeb Nonmetallic Flex-Core cell confiation as opposed to the standard hexagonal cell honeycomb provides for exceptional formability into compound curvatures with reduced anticlastic curvature and controlled buckling of cell walls. When formed into tight radii, HexWeb Nonmetallic Flex-Core provides higher shear strengths than comparable hexagonal cores of equivalent density. HexWeb Nonmetallic Flex-Core applications exist wherever extreme curvature dictates a flexible cell geometry, e.g. radomes, ducts, leading edges of wings and stabilizers.
