ABSTRACT:
The invention relates to a method of making a casing-and-diverging-portion unit, the method comprising the following steps:forming fiber reinforcement from a first fiber preform made with a first type of fiber and a second fiber preform made with a second type of fiber different from the first type of fiber, said second preform being placed on the first preform;maintaining the fiber reinforcement in tooling so that it has a shape identical to the shape of the casing-and-diverging-portion unit that is to be made; andimpregnating said fiber reinforcement with a thermosetting resin and impregnating the resin.
