The invention relates to the technical field of composite material simulation, in particular to a digital modeling method and device for a composite material grid structure. The method is applied to finite element simulation software and comprises the steps that finite element modeling is carried out on grid nodes and a mold of a composite material in a digital unit embedding mode, node compaction simulation is carried out on a grid node model obtained through modeling, and a target node model is obtained; performing region division on the target node model, and calculating a fiber volume fraction of each region; modeling is conducted on the grid structure of the composite material, an initial grid structure model obtained through modeling is split according to a region division result, a corresponding fiber volume fraction is given to each region obtained through splitting, and a target grid structure model of the composite material is obtained. According to the scheme, different fiber volume fractions are g
