1. A method of manufacturing an expandable and contractible honeycomb panel having a front side and a back side, said honeycomb panel comprising a plurality of elongated precursor tubular cells, said precursor tubular cells being constructed of foldable and creasable material, said method comprising the steps of (a) placing a first strip of a first material substantially parallel to a second strip of a second material in an overlapping configuration; (b) directly joining said first strip and said second strip, forming a dual-laminate component; (c) folding said dual-laminate component into a precursor tubular cell; (d) repeating steps (a) through (c) to create said plurality of precursor tubular cells; and (e) connecting said plurality of precursor tubular cells to form said honeycomb panel such that only said first material is on said front side of said honeycomb panel and said first and second materials are on said back side of said honeycomb panel.
