This invention relates to the technical field of composite material preparation and discloses a method for needle-punching preforms. The method specifically includes the following steps: obtaining the cross-sectional contour information of the preform; dividing the cross-sectional contour into multiple cells; generating multiple needle-punching points in each cell; and needle-punching the preform according to the positions of the multiple needle-punching points. The needle-punching method for preforms of this application can improve the uniformity of fiber density within the preform and improve the finished quality of the preform.
