ABSTRACT:
Disclosed is a method for preparing a carbon honeycomb structure that includes the steps of: alternately stacking a plurality of corrugated sheets each of which is produced by corrugating a supporting base of carbon fibers impregnated with an epoxy resin prepolymer and then curing the prepolymer, and a plurality of flat sheets, each of which is prepared by curing a supporting base of carbon fibers impregnated with an epoxy resin prepolymer, through a node bond adhesive; curing the adhesive to form a honeycomb structure; dipping the resulting honeycomb structure in a phenolic resin prepolymer solution; evaporating the solvent; then curing the phenolic resin prepolymer; repeating these dip, evaporation and curing processes to coat the honeycomb structure with a predetermined amount of the phenolic resin; and cutting the coated honeycomb structure to a predetermined thickness. In other embodiments, instead of alternatively stacking the plurality of corrugated sheets and the plurality of flat sheets, either a plurality of the corrugated sheets are stacked or a honeycomb expanding technique is used with the supporting bases.
