The invention proposes a method for manufacturing a grid for a cascade-type thrust reverser of a jet engine, the method comprising the following steps: a) manufacturing a first component comprising continuous or long fibres pre-impregnated with a thermoplastic or thermosetting resin; b) manufacturing, subsequently or concomitantly to step a), a series of second components each comprising discontinuous fibres pre-impregnated with a thermoplastic or thermosetting resin, the step b) being carried out such that the second components are arranged transversely to a longitudinal direction of the first component on at least one side of the first component, and spaced apart from each other in this longitudinal direction, so as to form a comb-shaped structure in which the second components are consolidated with the first component. 本发明提出了一种用于制造喷气发动机的级联型推力反向器的格栅的方法，所述方法包括以下步骤：a)制造第一部件，该第一部件包括由热塑性的或热固性的树脂预浸渍的连续纤维或长纤维；b)在步骤a)之后或与步骤a)一起制造一系列第二部件，每个第二部件都包括由所述热塑性的或热固性的树脂预浸渍的不连续纤维，步骤b)进行成使得第二部件一方面在第一部件的至少一侧上相对于第一部件的纵向方向横向地布置，
