A developable structural part, such as a component, includes at least one layer made from a resin-impregnated fabric (prepreg) and at least one layer made from wound threads, yarns, rovings or ribbons. At least one constant thread tension, but preferably a thread tension increasing from layer to layer, is applied during winding of the threads, yarns, rovings or ribbons. An outer ply is always formed of wound threads, yarns, rovings or ribbons. A process for producing the structural parts, a thermal insulation cylinder, a protective tube, a heating element, a stay pipe, a hot-press die and a thermal insulation element are also provided. The developable component or structural part can be obtained due to a combination of the application of fabric prepreg layers and windings made from threads, yarns, rovings or ribbons. The component or structural part has particularly high strength, outstanding mechanical properties and chemical resistance after curing of the resin matrix, or after curing and carbonizing, or after curing, carbonizing and graphitizing.
