摘要 |
The invention concerns a pipe having a wall comprising at least an intermediate layer (3, 4) to provide mechanical strength, and two sealing layers (1, 2) located on either side of the intermediate layer. The wall comprises an intermediate web (5) of shape memory yarns arranged and oriented such that their contraction, when the temperature rises, counters the mechanical deformation of the wall under the effect of a pressure. The invention is particularly applicable to a hydraulic accumulator, for vehicle brake systems.
