Device (20) for impregnating fibres (12) with resin (32), comprising a hollow peripheral element (22) that has a main axis (A) and a central element (30) coaxial with the peripheral element (22) and housed at least partially inside the latter. A circumferential injection chamber (42) is delimited between the internal wall of the peripheral element (22) and the external wall of the central element (30), said injection chamber having an inlet end (42A) and an outlet end (42B), and the device comprises resin conveying means communicating with said injection chamber. A unit for manufacturing a hollow profile section by pultrusion comprising such an impregnation device and a corresponding method of manufacture are also divulged. |
