This invention provides a method for the step-by-step pre-compacting integral molding of thermoplastic grating structures, belonging to the field of composite material molding technology. First, thermoplastic prepreg is laid in a mold. Under room temperature conditions, vacuum assistance and corresponding pressure are applied to perform multiple step-by-step static pre-compaction processes to remove interlayer air and reduce prepreg gaps. The laying and pre-compaction operations are repeated until the target thickness is reached. Then, the mold is heated and pressurized in the same mold to mold the composite material of the grating structure in one step.
