Abstract (en)
[origin: WO2020182959A1] Process for manufacturing a preimpregnated fibrous reinforcement (1) composed of a reinforcement made of natural plant fibers (2) impregnated with a thermoplastic polymer (3), comprising the steps: placing a first strip (4) of reinforcement made of natural plant fibers (2) and a second strip (5) of thermoplastic nonwoven (3) with a melting temperature Tm in contact with one another; said strips (4,5) are conveyed to first a heating zone (9) maintained at a temperature T1 below Tm; said strips (4,5) are conveyed to a second heating zone (11) maintained at a temperature T2 above Tm; said complex (13) is pressed and is conveyed to a cooling zone (15) in order to obtain said reinforcement.
