Summary:The invention proposes a method for manufacturing a grille for a cascade type thrust reverser, of a jet engine, said method including the following steps: a) manufacturing a first component comprising continuous or long fibres, pre-impregnated by a thermoplastic or thermosetting resin; b) manufacturing, subsequently or together with step a), a series of second components each including discontinuous fibres, pre-impregnated by a thermoplastic or thermosetting resin, step b) being carried out such that the second components are, on the one hand, arranged transversally with respect to a longitudinal direction of the first component on at least one side of the first component and, on the other hand, spaced from one another according to this longitudinal direction, so as to form a comb-shaped structure, wherein the second components are consolidated to the first component.. La invención propone un método para la fabricación de una rejilla para un inversor de empuje tipo cascada, de un motor a reacción, dicho método incluye los siguientes pasos: a) fabricar un primer componente que comprende fibras continuas o largas, pre-impregnadas por una resina termoplástica o de termofraguado; b) fabricar, subsecuentemente o junto con el paso a), una serie de segundos componentes cada uno incluyendo fibras discontinuas, pre-impregnadas por una resina termoplástica o de termofraguado, paso b) se realiza de modo que los segundos componentes son, por un lado, dispuestos transversalmente con respecto a una dirección longitudinal del primer componente en por lo menos un lado del primer componente y, por el otro lado, separados uno del otro de acuerdo con esta dirección longitudinal, a modo de formar una estructura con forma de peine, en donde los segundos componentes son consolidados al primer componente.
