摘要
Reinforcing element (9) for inserting in a hollow body, especially for a vehicle body spar, comprises a support (10) and a foaming composition (11) surrounding the support. The quantity of foaming composition used allows the gap between the support and the hollow body at least in one or more sections to be almost or completely filled on foaming of the composition. The support and the foaming composition are flexible. The reinforcing element is available in strands. Preferred Features: The support is a flexible tube. The foaming composition is distributed non-uniformly along the tube in an undulating structure.
