ABSTRACT:
A new honeycomb core structure of heat-resistant aromatic polyimide is disclosed. The structure comprises plural aromatic polyimide sheets wherein adjoining two aromatic polyimide sheets are combined to each other with a heat resistant adhesive at adhesive regions arranged between the two sheets at equal intervals and the adhesive regions on one side of any aromatic polyimide sheet are located at positions shifting from positions of adhesive regions arranged on another side of the sheet. The honeycomb structure is formed by extending the combined aromatic polyimide sheets in the direction vertical to the plane of the polyimide sheets.
