Abstract
Disclosed is a multi-layered composite panel. The multi-layered composite panel comprises at least two sheets of thin plates with continuous waveform patterns having the same pitch and different heights in one direction are overlapped. In the multi-layered composite panel, an air layer is formed between the overlapping thin plates, orthogonal pressing portions, which divide the waveform patterns on the top and the bottom of the thin plates into the unit of triangle-patterned cell by being pressed orthogonally to cross each other on the top and the bottom of the thin plates overlapping in the orthogonal direction crossing the direction of the waveform patterns, are formed and an undercut portion is formed by pressing the centers of both sides connecting a groove and a ridge of each cell on the top and the bottom of the thin plates with opposite orthogonal pressing portions.
