The invention relates to a reinforcing element for a structural profile, in particular for a circular, oval or elliptical structural tube, comprising a composite structure having a woven layer of hollow-column-type, spirally wound fiber bundles, which form an inner side surface for receiving the structural profile, wherein the fiber bundles are each embedded in a matrix material having an electroactive polymer which can be stretched along the longitudinal extension of the fiber bundles by applying a voltage such that the composite structure can be stretched by applying the voltage in order to introduce the structural profile into the composite structure and can be contracted by switching off the voltage, therefore, the structural profile is fixed on the side surface in the composite structure.
本发明涉及一种用于结构型材的加强元件,尤其是用于圆形的、卵形的或椭圆形的结构管,所述加强元件包括复合结构,所述复合结构具有空心柱式的、螺旋形缠绕的纤维束的编织层,所述纤维束形成构成用于容纳结构型材的内部侧表面,其中纤维束分别嵌入基质材料中,所述基质材料具有电活性的聚合物,所述聚合物能够通过施加电压沿着纤维束的纵向延伸拉伸,使得复合结构能够通过施加电压伸展,以便将结构型材引入复合结构中,并且能够通过切断电压收缩,以便将结构型材在复合结构中固定在侧表面上。
