Three-dimensional woven forming technology and equipment

Abstract

To meet requirements of high performance and light weight of parts in equipment, automobile and mechanical industries, etc. coupled with problems during weaving such as simple structure, small size, complex process, low machine automation, poor fiber volume fraction of products, high void fraction of resin impregnation and difficulty of making large and complex structure, a new weaving method for three-dimensional hybrid woven with composite material is provided. Fibers are weaved to structures along with a digital guide template controlled by computer and parts are formed after resin being impregnated from outside to inside. Fabric of three-dimensional hybrid woven method based on the board, method of resin impregnation from outside to inside of three-dimensional hybrid woven fabricated part, and development of test platform for three-dimensional hybrid woven parts and fabric test for typical parts are mainly studied. This new forming technology improves flexibility and operability in forming process of large parts, and has great academic value, active meaning in science study and good foreground in engineering applications.
