Abstract

The invention relates to a method for producing a composite body and to a composite body produced using the method, wherein the composite body (10) is formed as a pressure pipe or as a pressure container, wherein the composite body is composed of a main body (13) that is made of steel and of a coat (14) that is made of a fiber composite (15), said coat enclosing the outside of the main body at least in some sections, wherein, for forming the fiber composite, a fibrous material is wound around the main body, wherein the fibrous material is impregnated with a resin before or after winding, wherein the wound and impregnated fibrous material is heated in order to form the fiber composite, wherein the method is carried out in situ on a built-in pressure pipe or pressure container, wherein the wound and impregnated fibrous material is heated to up to 700° C.
