1. A method for connecting a fiber composite work piece and a load introduction device to one another, said method comprising steps of:
positioning the fiber composite work piece and the load introduction device in an arrangement relative to one another, thereby providing a cavity between a surface of the fiber composite work piece and an adhesion surfaced provided on the load introduction device;
temporarily securing the fiber composite work piece and the load introduction device to one another by external means, wherein the external means comprises one of at least one robot arm, at least one tensioning means, at least one holding clamp, at least one holding means, and at least one pressing means;
injecting an adhesive into the cavity through a first opening defined in one of the load introduction device and the fiber composite work piece or between the load introduction device and the fiber composite work piece;
wherein the injecting of the adhesive is at an application pressure for an application time-period, wherein the application pressure does not exceed a limit pressure and the application time period does not exceed a limit time period;
wherein the injecting of the adhesive occurs without temporary or permanent alteration of the position of the load introduction device and the fiber composite work piece relative to one another;
wherein the fiber composite work piece and the load introduction device are secured to one another for the duration of the injecting of the adhesive into the cavity; and
expanding the adhesive within the cavity.
