Three-dimensional weaving forming method for composite material

Abstract

The invention discloses a three-dimensional weaving forming method for a composite material, and belongs to the cross field of weaving and manufacturing. The method comprises the following steps of: performing layered design according to the characteristics of a part structure, and optimizing a weaving path; arranging weaving guide posts on a controllable digital arrangement template at intervals according to certain rules; after a guide sleeve passes through the hollow guide posts along the Z direction and is turned outwards, fixing the guide sleeve on the controllable digital template; selecting a silk material for weaving the layer; after the weaving of one layer is finished, lowering the controllable digital arrangement template, and driving the guide sleeve to expose for a distance to form a new layer of arrangement template; weaving layer by layer till the weaving of the whole part is finished; detaching and sewing the part; and soaking the part into resin to form a composite material part. According to the method, the quick prototyping technology and the weaving technology are organically combined to realize three-dimensional weaving of the complex functional part; and meanwhile, composite material preparation and part formation are integrated, so that manufacture of the complex functional part is realized.

Description

technical field [0001] The invention relates to a novel method and equipment for three-dimensional weaving of functional components, belonging to the intersecting fields of textile and manufacturing. Background technique [0002] Three-dimensional weaving technology is known as one of the most advanced composite material manufacturing technologies in the world. Three-dimensional weaving is a three-dimensional seamless and complete structure obtained by interweaving long and short fibers. Its technological characteristics are that it can produce regular shapes and special-shaped solid bodies and can make structural parts multifunctional—that is, weaving multi-layer integral components. [0003] In the early 1980s, Dr. R. Florentine of Quadrax Advanced Materials Company proposed a four-step processing technology. In 1988, DuPont's Popper and McConnell developed a two-step processing technology, which perfected the three-dimensional weaving process theory system. The three-dim...
