<p>A reinforced composite corrugated body characterized in that, in order to improve the strength and processability thereof, a corrugated body is formed in such a manner that a sheet material is provided with corrugated lines having vertically arranged alternate ridges and grooves in a smooth meandering waveform in the horizontal direction in such a manner as to define the substantial amplitude ratio H/L of the corrugated line at 0.4 to 1.4 inclusive, the substantial meandering ratio D/N at 0.35 or below, the substantial meandering overlapping ratio D/L at 0.5 or above, and the width narrowing ratio (i) in the direction in which the corrugated line extends at stretch strain ratio of the sheet material +8 % or below, and that the crest and bottom of each corrugated line have curved, narrowly chamfered or shoulder-rounded cross sections, and that at least one side of the corrugated body is lined with a flat plate.</p> |
