摘要： The present invention provides a method for producing a honeycomb core having excellent thermal stability, mechanical properties and a rapid setting speed, which comprises applying adhesives onto ribbon type of carbon fiber fabrics at regular intervals so as to form the specific size of a cell, attaching the ribbons in a layered form and heat setting and expanding the attached portion to form a basic honeycomb core and then impregnating and setting the basic honeycomb core in phenol resin containing 0.5 to 4% by weight of graphite powder having 0.3 to 2 .mu.m of average diameter. This method is characterized by the fact that fiber breakage due to thermal decomposition gas occurring in the setting treatment is prevented and the dispersing effect of surface of graphite is maximized, and thereby the thermal and mechanical properties of the honeycomb core can be optimized.
