Abstract:
A weaving and needling integrated preform formation method, comprising the following steps: moving a core mold (21) in a certain direction along an axis of a weaving machine (1) by arranging grabbing devices at two ends of the weaving machine (1), and at the same time, performing weaving to form a first layer of fabric (25) on the surface of the core mold (21); laying a mesh tire (26) above the first layer of fabric (25) by means of a mesh tire automatic laying device, and performing pre-needling on a mesh tire (26) layer by means of a needling device, so that the mesh tire (26) can fit the surface of woven fabric; activating the weaving machine (1) again, moving the core mold (21) in the opposite direction, and at the same time, performing weaving to form a second layer of fabric (28) on the surface of the mesh tire (26); repeating the above steps to realize alternate fitting of the multiple layers of woven fabric and the mesh tires (26); and finally, performing main-needling on a preform by means of the automatic needling device to realize Z-directional enhancement of the preform. Further provided is a preform formation device used to realize the weaving and needling integrated preform formation method.
