Hexcel® HexWeb® HDC-G-327 - 3/16 - 15.0 (R2) Heavy Density Core  (discontinued **)
Categories: Other Engineering Material; Composite Core Material; Composite Fibers

Material Notes: Designation: Material-Cell Size (inches)-Density
HexWeb® HDC is a fabric reinforced honeycomb, typically made from either fiberglass or carbon prepreg. A thermosetting node adhesive is used with either a thermoplastic or thermoset resin for the web impregnations. The product was developed for use in temperatures up to 500°F. Depending on the constituent resin system, the product may be suitable for short exposures at higher temperatures.

Features: High compression strength non-metallic honeycomb available; Formability tailored to customer's needs; Low-moisture pickup; High thermal stability, very low coefficient of thermal expansion; Proven history in service; High corrosion resistance.
Applications: HexWeb® HDC is used in sandwich structure as a replacement for potting compound in hard points or where extremely high compressive or shear strength is required. Using HexWeb® HDC in lieu of potting compound reduces process steps, improves part quality and reduces weight in the overall structure.
