Composite roof cross member for vehicle body and method for electrophoretic coating of vehicle body comprising composite roof cross member

The invention relates to a composite roof cross member for a vehicle body. The composite roof cross member includes at least one metal beam component and at least one CFRP component. The roof cross member may be connected to the remainder of the vehicle body such that a tension load exerted on the roof cross member by the remainder of the vehicle body is mainly or only carried by the metal beam component. The invention also relates to a method for electrophoretic coating of a vehicle body comprising a composite roof cross member. 本发明涉及一种用于车辆主体的复合式车顶横梁构件。该复合式车顶横梁构件包括至少一个金属梁部件和至少一个CFRP部件。车顶横梁构件可连接到车辆主体的其余部分，使得由车辆主体的其余部分施加在车顶横梁构件上的张力负荷主要或仅由金属梁部件来承载。本发明还涉及一种用于对包括复合式车顶横梁构件的车辆主体电泳涂覆的方法。
