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 an upper panel layer, a lower panel layer and a framework supporting layer located between the upper panel layer and the lower panel layer; the framework supporting layer comprises a first supporting framework and second supporting frameworks; the first supporting framework is of a latticed structure and comprises at least two layers of transverse supporting frames and a plurality of longitudinal supporting frames; each layer of transverse supporting frame is formed by arranging the multiple transverse supporting frames in parallel at intervals; the longitudinal supporting frames sequentially and longitudinally penetrate through each layer of transverse supporting frame upwards from the lower panel layer to the lower surface of the upper panel layer; the longitudinal supporting frames are evenly distributed at intervals in the front-back direction and the left-right direction; the second supporting frameworks are arranged between the upper panel layer and the transverse supporting frame on the uppermost layer and between the lower panel layer and the transverse supporting frame on the lowermost layer; and a resin foam layer is filled in gaps of the framework supporting layer. The framework supporting layer is distributed more compactly; higher impact resistance is achieved; when the board is impacted, collapse is not prone to occurring; and the service life of the whole board is prolonged.

    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。包括上下面板层以及位于两者之间的骨架支撑层,骨架支撑层包括第一和第二支撑骨架;第一支撑骨架为网格状结构,包括至少两层横向支撑架和若干个纵向支撑架,每层横向支撑架由若干个横向支撑架间隔平行排列组成,纵向支撑架自下面板层向上依次纵向贯穿每层横向支撑架直至上面板层下表面,纵向支撑架之间呈前后、左右间隔均匀分布;第二支撑骨架设置在上面板层与最上层的横向支撑架之间以及下面板层与最下层的横向支撑架之间;骨架支撑层的空隙中填充有树脂泡沫层。本发明骨架支撑层分布更密实,具有更强的抗冲击性,当板材受到撞击时,不易坍塌,整个板材的使用寿命得到延长。
