THE METHOD OF CONTINUOUSLY FORMING A SMOOTH SURFACED, COMPOSITE STRUCTURAL MEMBER CONSISTING OF A FACE PLATE AND A CELLULAR CORE WHEREIN OPPOSING PORTIONS OF THE ELEMENTS OF SAID STRUCTURE HAVE DIFFERENT LINEAR SURFACE AREAS AND ARE SECURED TOGETHER BY A BONDING MATERIAL THAT REQUIRES HEATING TO A CRITICAL TEMPERATURE AND COOLING IN ORDER TO EFFECT A BOND BETWEEN THE ELEMENTS OF THE STRUCTURE, THE STEPS WHICH INCLUDE FEEDING THE ELEMENTS OF A COMPOSITE STRUCTURE FORWARD IN ALIGNED RELATION TO EACH OTHER, PREHEATING SAID ELEMENTS AS THEY ARE BEING FED FORWARD TO A TEMPERATURE CLOSE TO BUT BELOW THE CRITICAL TEMPERATURE OF A BONDING MATERIAL, SAID ELEMENTS BEING FREE TO EXPAND INDEPENDENTLY OF EACH OTHER DURING SUCH PREHEATING, THEN BRINGING SAID ELEMENTS INTO CONTACT WITH EACH OTHER UNDER PRESSURE WITH THE BONDING MATERIAL INTERPOSED THEREBETWEEN, THEN SUPPLYING A FINAL INCREMENT OF HEAT TO SAID ELEMENTS, SAID FINAL INCREMENT OF HEAT BEING SUFFICIENT TO RAISED THE TEMPERATURE OF THE BONDING MATERIAL TO ITS CRITICAL TEMPERATURE AND THEN COOLING THE COMPOSITE STRUCTURE THUS FORMED TO A TEMPERATURE BELOW THE CRITICAL TEMPERATURE OF THE BONDING MATERIAL.
