A summary of the research status of composite material preforming and equipment at home and abroad is presented at first, in which the current problems in the forming process in terms of low labor-intensive manufacturing efficiency, difficult control of precise shape forming, and low degree of automation are analyzed. Then a digital three-dimensional weaving forming method and a variable curvature preform placement-winding-needle punching integrated forming method are proposed. Finally, some future development suggestions for composite material forming technology and equipment are put forward to promote the technology towards high efficiency, high performance, high quality, automation and digitalization, and upgrade the manufacturing level of fiber preform based composite components.
