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 panel layer, each longitudinal reinforcing rib unit comprises a plurality of longitudinal reinforcing ribs, and the longitudinal reinforcing ribs are perpendicular to the first panel layer from front to back and are evenly distributed at intervals; and gaps among the reinforcing ribs are filled with the filling layer. The mechanical property of the composite board is greatly enhanced, and the probability of damage caused by impact is reduced.

    本发明属于复合板材的制备领域,公开一种高强度复合板材及其制备方法。由下至上包括第一面板层、中间层、第二面板层,中间层由加强筋层和填充层组成,加强筋层由若干个横向加强筋单元和若干个纵向加强筋单元组成;横向加强筋单元平行于第一面板层间隔分布,每个横向加强筋单元包括若干个横向加强筋,横向加强筋自下而上平行于第一面板层均匀间隔分布;相邻两个横向加强筋单元之间分布一个纵向加强筋单元并且纵向加强筋单元垂直于第一面板层,每个纵向加强筋单元包括若干个纵向加强筋,纵向加强筋自前而后垂直于第一面板层均匀间隔分布;填充层填充在加强筋之间的空隙中。本发明极大增强了复合板材的力学性能,减小因受到冲击发生破损的概率。
