Hexcel® HexWeb® HTP-3/8-4.5 Fiberglass/Phenolic Honeycomb
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoset; Phenolic
Material Notes:	Description: HexWeb® HRP® is a fabric reinforced honeycomb in which a heat-resistant phenolic resin is used both for initial and final impregnations. The 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 two formable geometries – OX-Core® and Flex-Core®. Features: High strength up to 350° Good insulation properties Good dielectric properties Good bonding surface Readily heat formed Applications: HexWeb® HRP/HTP 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.
