Front end module structure of vehicle

A method for making a front end module structure of a vehicle, comprising:

• adapting an unitary resin-made front end panel to be mounted at both ends on a pair of opposed front side members of the vehicle;
• retaining at least a radiator of the vehicle with the front end panel having a retaining portion;
• positioning an upper reinforced portion over the radiator, which is continuously extending in a width direction of the vehicle and opposed rib-like flanges downwardly extending from the upper reinforced portion;
• and
• molding the front end panel integrally with a metal-made reinforcement member at a portion of the upper reinforced portion so that the metal-made reinforcement member is integrated with the front end panel all along said portion of the upper reinforced portion, wherein the upper reinforced portion has a horizontally thrown U-shaped or closed sectional configuration and the metal-made reinforcement member is arranged along an outer surface of the upper reinforced portion to extend in a width direction of the upper reinforced member, and
• the metal-made reinforcement member has a plurality of holes in which resin material of the upper reinforced portion is integrally formed in, through and around said holes and onto the outer surface of the metal-made reinforcement member so that the resin material in the holes mechanically communicate with the metal-made reinforcement member.
