Method for the resistance welding of fiber-composite components to give a fiber-composite structure, fiber-composite structure and fiber-composite component

A method for resistance welding of two fiber-composite components to give a fiber-composite structure, the method comprising:

• arranging a plurality of individual conductive fibers in a form of a first layer having a first portion of the plurality of individual conductive fibers and a second layer having a second portion of the plurality of individual conductive fibers, the first layer and the second layer being within a jointing region of the two fiber-composite components, wherein:
• all conductive fibers of the first portion of the plurality of individual conductive fibers extend in a first direction within the first layer;
• all conductive fibers of the second portion of the plurality of individual conductive fibers extend in a second direct, the second direction being transverse to the first direction within the second layer;
• the first layer is on top of the second layer, such that the conductive fibers in the first layer and the conductive fibers in the second layer form a grid;
• the plurality of individual conductive fibers are arranged between the fiber-composite components;
• the fiber-composite components are arranged on opposite sides of the jointing region;
• and
• each of the plurality of individual conductive fibers comprises a carbon fiber with an electrically insulating coating;
• passing an electric current through the plurality of individual conductive fibers to heat the jointing region to a welding temperature and melt the fiber-composite components in the jointing region;
• and
• hardening the jointing region to bond the two fiber-composite components by way of the jointing region to give the fiber-composite structure.
