Disclosed is a vehicle interior hybrid panel having a lightweight reinforcement structure. A hybrid panel for vehicle interior having a lightweight reinforcing structure according to the present invention includes a resin panel that is injection-molded to constitute an inner side of the vehicle; A metal reinforcing frame that is inserted into a mold for reinforcing a region of the resin panel and integrated with the resin panel in a partially buried state; And a reinforcing rib that flows toward the non-embedded surface of the reinforcing frame through a plurality of rib holes formed in the reinforcing frame when the resin panel is ejected and is injection-formed in a protruding form to further reinforce the resin panel. do. According to the present invention, a metal reinforcing frame inserted into a mold without a locator for reinforcing the resin panel to be injection-molded, and a reinforcement that is injection-formed in a form protruding through a plurality of rib holes formed in the reinforcing frame during injection to be integrated with the resin panel. As the ribs overlap each other and reinforce the resin panel, the impact resistance and rigidity of the resin panel itself can be secured more firmly.
