1. A manufacturing method for a three-dimensional orthogonal woven composite outlet guide vane, comprising the following steps:
(1) setting weaving parameters of a vane profile area and parameters of a platform area according to requirements for geometric dimensions of an outlet guide vane;
(2) setting a bifurcation of a vane profile-platform junction according to the requirements for the geometric dimensions of the outlet guide vane in step (1) and requirements for mechanical performance of the outlet guide vane under different loads;
(3) weaving a preform of the three-dimensional orthogonal woven outlet guide vane according to conditions set in steps (1) and (2);
(4) sequentially forming the preform and manufacturing the three-dimensional orthogonal woven composite outlet guide vane;
step (2) comprises:
numbering wefts in the vane profile area of the preform of the three-dimensional woven outlet guide vane as w1−w2n along a thickness direction, wherein n is an integer; number of the wefts in the vane profile area is even; wefts numbered as wn+1 and wn+2 or wefts numbered as wn−1 and wn are located at a same layer in a two-fold form;
changing distribution of wefts by controlling a heald lifting mode of warps, so that positions of wefts in the vane profile-platform junction are changed along the thickness direction, and numbering changed wefts in the platform area along the thickness direction as w1*−w2n*; and
a set composed of weft number in the vane profile area and weft number in the platform area being in a one-to-one mapping relationship, and 2n wefts having 2n factorial methods of bifurcation.
