Beschreibung
Zusammenfassung:	The invention belongs to the field of preparation of composite boards, and discloses a high-strength composite board and a preparation method thereof. The high-strength composite board comprises a first panel layer, a middle layer and a second panel layer from bottom to top, the middle layer is composed of a reinforcing rib layer and a filling layer, and the reinforcing rib layer is composed of a plurality of transverse reinforcing rib units and a plurality of longitudinal reinforcing rib units; the transverse reinforcing rib units are parallel to the first panel layer and are distributed at intervals, each transverse reinforcing rib unit comprises a plurality of transverse reinforcing ribs, and the transverse reinforcing ribs are parallel to the first panel layer from bottom to top and are uniformly distributed at intervals; one longitudinal reinforcing rib unit is distributed between every two adjacent transverse reinforcing rib units, the longitudinal reinforcing rib units are perpendicular to the first pa
