The invention relates to a method for weaving a 2.5D angle-interlock preformed part with the section gradually decreasing. On the basis of a layer-layer angle-interlock weaving process, the method ischaracterized in that in the weaving process, with one end surface of the preformed part as a standard, according to the change of the size of the section of the preformed part and the movement law ofyarn, the quantity and positions of yarn-reducing points in a plane in the weaving direction are designed, and the yarn-reducing points are evenly distributed; by means of the methods of yarn reduction, yarn movement and yarn reed replacement, the section change of the preformed part is achieved, and the section-variable preformed part is woven. The method is simple and high in applicability, thewoven formed part is good in integrity, and the mechanical properties of composites can be improved.
