PCT No. PCT/AU84/00162 Sec. 371 Date Apr. 1, 1985 Sec. 102(e) Date Apr. 1, 1985 PCT Filed Aug. 28, 1984 PCT Pub. No. WO85/01014 PCT Pub. Date Mar. 14, 1985.A substantially planar reticulated material is formed by the conjunction of a plurality of strips of non-planar material so that the strips lie substantially perpendicular to the plane of the reticulated material with their edges lying coplanar with the reticulated material and forming opposite surfaces thereof. Each strip of nonplanar sheet material is formed on each opposite surface with a pattern of crests and valleys of repetitive wavelength such that each pattern repeat contains at least two crests and at least two valleys; in each pattern repeat the height of at least one crest or valley on at least one surface of the strip is different from that of at least one of the other respective crests and valleys on said surface; the recurring height difference produces a corrugation along the strip having a wavelength greater than the wavelength of the crests and valleys; and adjacent strips are abutted with the corrugation opposed to interfit at least one crest in a valley of each opposed corrugation. |
