The invention relates to the technical field of automobile manufacturing, and discloses an RTM wet molding process of a plate body. The RTM wet molding process comprises the following steps of sequentially stacking pre-processed fabrics from top to bottom, stacking 5-8 layers according to specific requirements, coating each layer of the fabrics with previously blended reinforcing resin to be wet, and transferring the wetted laminated fabric into a hot mold. According to the RTM wet molding process of the plate body, in the using process, reinforcing resin prepared in the plate body is fully mixed with various different resin materials and carbonized fibers, the firmness effect of the plate body are improved, , heat resistance, cold resistance, water resistance and adhesion resistance are achieved, the practicability of a vehicle body is improved, the reinforcing effect in the plate body is further improved through the carbonized fibers, the service life of the plate body is prolonged, and meanwhile, the mode
