Resin transfer molding method and hammering excitation device

The invention relates to the technical field of resin transfer molding, in particular to a resin transfer molding method and a hammering excitation device used for the method. The hammering excitationdevice comprises a support, a driving part and a hammering part, wherein the driving part is arranged on a frame body, and the hammering part is connected with the driving part. The hammering excitation device can be placed on a forming die through a support, the driving part drives the hammering part to reciprocate in the vertical direction, and a to-be-hammered area of the forming die is hammered. The hammering excitation device is placed on the forming die through the support and is convenient to use, the driving part drives the hammering part to reciprocate to hammer the forming die, stress waves are applied to the forming die, infiltration of resin and fiber is promoted, delamination defects of workpieces are avoided, and the yield of the workpieces is improved. According to the method, the stress waves are
