A method for manufacturing a structural component for motor vehicles formed as door inner skin, door module or assembly carrier of a motor vehicle door by hot forming of a plate-shaped organo-sheet of thermoplastic material with embedded continuous fibers, characterized in that the continuous fibers or continuous fiber layers (41 - 46) for embedding in the thermoplastic plastic matrix of the semi-finished product are positioned in angular positions corresponding to different loading directions of the structural component, namely that - the continuous fibers or continuous fiber layers (41 - 46) are oriented in pull-off direction of a window pane of a window lifter mounted on the structural component, and - the continuous fibers or continuous fiber layers (41 - 46) are oriented in direction of the pull connection between a door lock and a door hinge of the motor vehicle door or the continuous fibers or continuous fiber layers (41 - 46) are oriented in loading direction of a door closing handle, and that in addition a reinforcing element is provided in a region of increased load of the structural component, which is oriented in direction of pull-off forces exerted on the structural component when actuating the window lifter or in direction of closing forces exerted on the structural component by an interior door handle, wherein an adapter is provided for positive connecting the reinforcing element with the organo-sheet and for force distribution of the loaded structural component, - which is injection-molded to the organo-sheet in one piece and includes paths of force with which a cohesive connection with the reinforcing element is produced, wherein proceeding from a mounting opening the adapter expands in direction of the connecting region of the reinforcing element, and - for which on the side of the organo-sheet opposite the injection molding side of the adapter a through-molding cavity is provided in a molding die for manufacturing the structural component, which is filled with the plastic matrix in the region of the reinforcing element by pressing the material of the plastic matrix through the structure of the organo-sheet. - the continuous fibers or continuous fiber layers (41 - 46) are oriented in pull-off direction of a window pane of a window lifter mounted on the structural component, and - the continuous fibers or continuous fiber layers (41 - 46) are oriented in direction of the pull connection between a door lock and a door hinge of the motor vehicle door or the continuous fibers or continuous fiber layers (41 - 46) are oriented in loading direction of a door closing handle, - which is injection-molded to the organo-sheet in one piece and includes paths of force with which a cohesive connection with the reinforcing element is produced, wherein proceeding from a mounting opening the adapter expands in direction of the connecting region of the reinforcing element, and - for which on the side of the organo-sheet opposite the injection molding side of the adapter a through-molding cavity is provided in a molding die for manufacturing the structural component, which is filled with the plastic matrix in the region of the reinforcing element by pressing the material of the plastic matrix through the structure of the organo-sheet.
