Abstract

L'invention porte sur une barre renforcée de fibres destinée à l'armature de béton, laquelle barre comprend au moins: une première zone (1) formée d'un noyau central, composé de fils de filaments de fibres de verre ou d'un autre type de renfort unis entre eux par des résines polymériques; une deuxième zone (2) qui enveloppe la première zone et qui est formée de tissus de renfort, de préférence en fibres de verre, lesquels tissus de renfort, en plus d'envelopper et de renforcer la première zone, la protègent contre les températures élevées; et une troisième zone (3) que l'on forme en ajoutant à la deuxième zone (2) un granulat lié par des résines résistant aux hautes températures.
