Abstract
A locally reinforced honeycomb core panel having a honeycomb core, at least one coiled insert in at least one honeycomb cell and at least one face sheet. These components are formed from high temperature resistant metals. Elongated foil strips are coiled into cylindrical shapes having diameters slightly less than the width of individual cells in the honeycomb panel and heights no greater than the depth of the cells. These coiled inserts are placed in individual cells in selected portions of the honeycomb core to locally improve density, strength and thermal transfer characteristics of the panel. The coiled inserts have sufficient resiliency so that when they are inserted into cells and allowed to unwind, they press tightly against the cell inside wall even if the cell shape has been distorted in handling. The cells are held in place by the face sheet(s) bonded to the honeycomb core. If desired, the coils may be bonded to the cell walls by diffusion bonding or brazing.
