A process of making a fibre-reinforced polymeric material comprises sliding a fibre bundle over an arcuate support surface (2) in the line of the arc, and injecting into: the bundle a molten or liquid polymer through a plurality of slots (4) in the surface, each slot being transverse to the bundle. The process allows effective impregnation of materials, at relatively high production speed and low capital cost.

Procédé de fabrication d'un matériau polymère renforcé par des fibres consistant à glisser un faisceau de fibres sur une surface (2) de support en forme d'arc, le long de cet arc, et à injecter dans le faisceau un polymère liquide ou en fusion à travers une pluralité de fentes (4) ménagées dans la surface, chaque fente étant située transversalement par rapport au faisceau. Ce procédé permet une imprégnation efficace des matériaux à une vitesse de production relativement élevée et à faible coût de revient.
