The invention belongs to the technical field of carriage plate preparation, and discloses a carriage plate and a preparation method thereof. The composite board comprises a first panel layer, a secondpanel layer, a sandwich layer and a framework supporting layer, the sandwich layer comprises a plurality of foam blocks, the framework supporting layer is latticed, the framework supporting layer isarranged between the first panel layer and the second panel layer, grids of the framework supporting layer are filled with the foam blocks, and the framework supporting layer, the first panel layer and the second panel layer are integrally formed. The preparation method comprises the following steps that a release film, first demolding cloth, a first fiber reinforced resin prepreg tape and a latticed fiber reinforced resin prepreg tape frame are sequentially laid from bottom to top; the resin foam composition is poured into a latticed fiber reinforced resin prepreg tape frame; a second fiber reinforced resin prepreg tape-second demolding cloth can be paved; and hot-pressing curing molding and demolding treatment can be carried out. The mechanical property of the carriage plate is greatly improved.
