HONEYCOMB FACESHEET MATERIAL AND HONEYCOMB MADE THEREWITH

摘要

HONEYCOMB FACESHEET MATERIAL AND HONEYCOMB MADE THEREWITH A honeycomb facesheet material (10), and honeycomb (22) made therewith, wherein the facesheet includes a layer of graphite paper (14) bonded to a layer of graphite cloth (12), woven from widely spaced graphite fibers (16). The facesheet (10) is impregnated with an epoxy resin during manufacture, and the facesheet (10) is bonded to an open end of the honeycomb (22) under elevated pressure and temperature to effect curing of the epoxy resin. The graphite paper (14) supports the layer of graphite cloth (12) during handling to prevent misalignment of the fibers (16), and also effects a widely distributed bond between the fibers (16) and the underlying honeycomb (22).
