    Abstract: This invention relates to processes for making a honeycomb comprising cells having edges forming a face of the honeycomb, the face defined by a plurality of points and having an area of curvature wherein at least two of the points are located in different tangential planes, comprising the steps of: a) bonding a plurality of sheets along parallel lines of adhesive, the sheets comprising 5 to 50 parts by weight thermoplastic material having a melting point of from 120° C. to 350° C., and 50 to 95 parts by weight high modulus fiber having a modulus of 600 grams per denier (550 grams per dtex) or greater, based on the total amount of thermoplastic material and high modulus fiber in the walls; b) pulling the bonded sheets apart in directions perpendicular to the plane of the sheets to form a honeycomb having cells; c) heating the honeycomb to soften the thermoplastic material; d) bending, molding, or forming the honeycomb in a mold or over a form having an area of curvature; and e) cooling the honeycomb to retain the shape of the area of curvature of the mold or form. Other processes for making a honeycomb include steps for impregnation, b-staging, and/or curing of the honeycomb with resin.This invention also relates to a shaped honeycomb made by this processes wherein less than 25 percent of the honeycomb cells in the area of curvature have a re-entrant angle of greater than 180°.
