Hexcel® HexWeb® HRP - 1/4 - 3.5 Fiberglass/Phenolic Honeycomb
Categories:	Ceramic; Glass; Glass Fiber; Other Engineering Material; Composite Core Material; Composite Fibers; Polymer; Thermoset; Phenolic
Material Notes:	Designation: Material-Cell Size (inches)-Density HexWeb® HRP is a glass fabric reinforced honeycomb in which a heat-resistant phenolic resin is used both for initial and final impregnations. This product was developed for use at service temperatures up to 350°F. However, it is also well suited for short exposures at high temperatures. The HexWeb® HRP-series honeycomb is available in the standard hexagonal configuration, as well as in the two formale geometries - OX-Core® and Flex-Core®. Features: High strength up to 350°F; Good insulation and dielectric properties; Good bonding surface; Readily heat formed. Applications: HexWeb® HRP has proven to be an excellent core material for radomes, aircraft structural parts and fairings, heat shields, and other assemblies that see elevated temperature service.
