Abstract: A method for producing a connection between a sandwich element and a metal element is disclosed herein. In this method, the sandwich element has an interlayer arranged between two cover elements. The method includes providing the sandwich element and the metal element; placing the sandwich element and the metal element in face-to-face contact at least partially overlapping; adding a fastener from the sandwich-element side while a base of the fastener extends within the sandwich element; and friction welding, from the metal-element side, to form a hybrid connection having a mechanical connection between the fastener and the sandwich element and a welding connection between the fastener and the metal element.

Abstract: A vehicle body component includes a basic element reinforced with a reinforcing element of fiber-reinforced plastics material. The basic element reinforced with the reinforcing element is a basic element of a pillar of a vehicle body or a roof element. The reinforcing element has a constant thickness or a variable thickness.

Abstract: The present disclosure provides a composite tube and a method for producing a composite tube for a vehicle body. The method includes the steps of: providing a metal tube; forming the tube into a prespecified shape; introducing a spray gun into the tube; and spraying on a fiber coating in at least one region of the inner side of the tube using the spray gun. The fiber coating is a matrix material with embedded fibers. The method further includes removing the spray gun from the tube, and hardening the fiber coating. The present disclosure also provides a motor vehicle having a vehicle body which includes a composite tube.

Abstract: The present disclosure relates to a method for producing a structural component for a motor vehicle, in particular a motor vehicle body component, which has a main body made of a metal material. The main body is provided at least partially with a reinforcing element made of a fiber-composite plastic. The method includes the steps of providing the main body, providing the reinforcing element, joining the main body and the reinforcing element together, and simultaneously heating the main body and the reinforcing element to a temperature and for a period of time which are chosen to be sufficiently high in order to harden both the metal material of the main body and also the fiber-composite plastic of the reinforcing element.

Abstract: The present disclosure relates to a vehicle body component, which comprises a basic element reinforced with a reinforcing element of fiber-reinforced plastics material. It is proposed that the basic element reinforced with the reinforcing element is a basic element of a pillar of a vehicle body or a roof element, the reinforcing element having a constant thickness or a variable thickness.
