Abstract

L'invention concerne une technique de fabrication de poteaux structuraux à partir d'un matériau composite en matrice thermoplastique, par enroulement filamentaire ou pultrusion. La forme finale du poteau (cylindrique, octogonale, conique ou autre) peut être obtenue par utilisation d'un mandrin d'acier ou d'un autre matériau rigide ou d'un matériau composite analogue, obtenu par pultrusion ou par une autre technique équivalente, pouvant être intégré dans le poteau final en tant que barrière chimiquement résistante à la corrosion. Les poteaux peuvent présenter, si nécessaire, des matériaux résistants au feu sur la surface extérieure. Les poteaux plus grands peuvent être constitués en segments facilement assemblables par emboîtement, par vis ou au moyen d'accessoires similaires. Les applications incluent le transport de lignes électriques aériennes ou le support de luminaires, d'éoliennes, de clôtures électrifiées et d'équipement urbain.
