Cells of a composite cell array are cured by placing tool blocks in the cells and inserting thermally conductive elements in each of the tool blocks. The thermally conductive elements are convectively heated by a flow of hot air. The heated conductive elements conduct heat to the tooling blocks, which then conduct heat to the cells to cure the composite and adhesive.
