Abstract:
1. A rigid element adapted to be joined to a support structure made of a polymeric material, the rigid element comprising: a stiffening structure made of a polymer-resin-based material; a single textile layer contacting the stiffening structure, the textile layer including electrically conductive yarns in the form of one of a warp and weft fabric and a non-woven fabric; and an outer layer contacting the single textile layer, the outer layer being made of a material that is compatible with the polymeric material of the support structure, wherein the single textile layer includes two protruding portions extending beyond sides of the stiffening structure, the two protruding portions being electrically connected to one another directly through the electrically conductive yarns such that current passes through the textile layer between the protruding ends causing the electrically conductive yarns to be heated through resistive heating.
