<p>Method of manufacturing a board-shaped sandwich material (1), comprising the steps of: - providing a board-shaped core (2) made of corrugated fiberboard, which core (2) has a top side (3a) and a bottom side (3b) and in which core (2) the tubular flutes (10) of the corrugated fiberboard extend essentially perpendicularly to the top side (3a) and the bottom side (3b) of the core (2); - application of chips and adhesive onto the top side (3a) and the bottom side (3b) of the core (2) so as to form a mat of chips (5a, 5b) on each side; - compression of the mats of chips (5a, 5b) by exerting press force (F 1 , F 2 ) orthogonally to the top side (3a) and the bottom side (3b) of the core, the adhesive in the mats of chips (5a, 5b) being brought to harden so as to form hard particle layers (6) on the top side (3a) and the bottom side (3b).</p> |
