Claim:
1. A joint arrangement of a first component and a second component of an aircraft or spacecraft having curved joint faces, comprising: a first component having a curved joint face; a second component having a curved joint face, the joint face of the first component and the joint face of the second component being arranged adjacent to each other; and a planar structure for the material-uniting joining of the first component and the second component arranged between the joint face of the first component and the joint face of the second component, wherein the planar structure is adapted for use between curved joint faces and is formed by at least a first reaction strand and a second reaction strand, the first reaction strand and the second reaction strand being woven, interlaced, knitted or spatially arranged by any combination thereof, wherein the first and second reaction strands have a substantially cylindrical core respectively, which is provided, at least in some areas, with a coating and wherein an exothermic reaction can be triggered in the coating by a supply of heat, to join the first component and second component by a substance-to-substance bond, the first component and the second component being adapted to at least partially melt and to a limited extent mix their materials in the surface region, wherein the coating is formed by at least five coaxially applied thin layers, a first, third and fifth layer being formed by titanium and a second and fourth layer being formed by nickel, the first layer being arranged on the substantially cylindrical core, the second layer being arranged on the first layer, the third layer being arranged on the second layer, the fourth layer being arranged on the third layer and the fifth layer being arranged on the fourth layer.
