Title (EN) IMPROVEMENTS RELATING TO REINFORCING BARS
(FR) AMELIORATIONS APPORTEES AUX BARRES D'ARMATURES
Abstract:
(EN) A bar is formed by drawing longitudinally extending resin-impregnated fibres (1) through forming eyes to remove excess resin, leaving an external surface which is non-smooth in appearance. After curing of the resin the bar can be used for reinforcing purposes and the roughened surface will tend to grip well within the material being reinforced. A secondary tow (2) can optionally be wound around the longitudinal fibres to give improved circumferential strength and to help prevent separation of the fibres.
(FR) La présente invention concerne une barre que l'on forme en étirant au travers d'un orifice de formage des fibres (1) imprégnées de résine s'étendant longitudinalement afin d'éliminer le surplus de résine et d'obtenir une barre présentant ensuite une surface extérieure d'apparence non lisse. Une fois la résine durcie, on peut utiliser la barre à des fins de renforcement, la surface rugueuse permettant à la barre de bien adhérer à l'intérieur du matériau à renforcer. Un câble auxiliaire (2) peut facultativement être enroulé autour des fibres longitudinales afin d'améliorer la résistance à l'effort transversal et d'empêcher que les fibres se séparent les unes des autres.
