Abstract
The invention relates to a three-dimensional weave-forming method for composites, comprising the following steps: dividing the CAD model into layers according to the structure of a component, designing by layers and optimizing weaving paths; disposing weaving guiding poles on a controllable digital layout template according to preset rules and intervals; In the direction Z, passing guiding sleeves through the hollow guiding poles and evaginating the guiding sleeves, and then fixing the guiding sleeves onto the controllable digital layout template; selecting filaments to weave; after the weaving of one layer thickness is finished, descending the template in the thickness by one layer to drive the guiding sleeves to expose outside a preset distance to form a new layer of layout template; weaving layer by layer until the whole component is finished; dismounting the component and sewing; and dipping the component in resin and finishing the manufacture of the part. According to the method, the rapid prototyping technology and the weaving technology are organically combined, so that the three-dimensional weaving of components with complex function is realized. Simultaneously, the prepara…
