The invention provides an implanting method of a prepreg reinforcing rod, a reinforced composite material laminated board and a manufacturing method. Through an implanting manner of a prepunched hole,fibers are extruded without being broken, so that damage to the fibers and the requirement for the rigidity of the reinforcing rod in the implantation process are effectively reduced; A method for controlling the implanting depth and angle of the reinforcing rod with high precision is beneficial to realizing an implanting manner that the reinforcing rod does not penetrate through surface layer fibers, can greatly reduce the damage of the reinforcing rod to the in-plane performance of a laminated flat plate, and effectively reduces influence on the in-plane compression strength while improvingthe bending delamination resistance of the laminated flat plate, so that bending strength of the composite material is further improved. The method can be used for all structures which are easy for generation of interlayer la
