| Résumé : |
This paper describes the in-situ manufacturing of a carbon fibre pipeline by means of an epoxy resin infusion process followed by vacuum consolidation. The process uses as a lost mould the existing reinforced concrete pipe with steel core in poor condition, which serves for the cooling process of a nuclear power plant reactor. The carbon fibre pipeline, which is buried at a depth of 4 to 9 metres, is designed to provide by itself the required structural resistance and tightness, without considering the contribution oh the existing pipeline. |
