摘要
The procedure for manufacturing thin profiled strips, made up of continuous unidirectional fibers embedded in a thermoplastic resin, consists of impregnating a lap (1) of parallel fibers with resin particles, achieving resin fusion, forming the profiled strip and of cooling the latter.PPThe lap (1) of fibers is dipped into a bath (26) of resin particles, mechanically impregnated with the particles, by feeding it for instance around rollers (15, 16, 17) immersed in the resin particles and the excess particles are removed to obtain the desired resin to fiber content ratio.PPUse of profiled strips obtained, in particular for outwardly reinforcing tubes or for producing moulded items.
