Embodiment 1
[0034] as attached Figure 1-4 As shown, the embodiment of the present invention provides a method for acupuncture of antenna cover profiling preforms, including the following steps:
[0035] S1, the first lamination unit 1 is laid on the outer surface of the mold 100, and the lamination unit includes at least one layer of fiber cloth 1a and one layer of net tire 1b along the thickness direction; the mold 100 here and the shape of the radome cover profiling preform Anastomosis, play a supporting role, can adopt double-layer structure or composite layer structure, the inner layer is made of steel material to provide support, and the outer layer is used to buffer the force of the needle and adopt elastic deformation material, such as rubber or silica gel;
[0036] S2, acupuncture the first lamination unit 1 along the thickness direction so that the short fibers 15 of the net tire 1b are brought into the interior of the fiber cloth 1a along with the needle punching action, and co...
Embodiment 2
[0057] Preferred embodiment 2, the step of laying the laminated unit includes:
[0058] S11B, continuously laying at least one layer of mesh tires on the outer surface of the mold;
[0059] S12B, adjusting the fiber gap of the net tire on the raised part of the mold so that the net tire coincides with the outer surface of the mold and forms a three-dimensional net tire cover;
[0060] S13B, laying at least one layer of fiber cloth continuously on the outer surface of the mold;
[0061] S14B, adjusting the fiber gap of the fiber cloth on the raised part of the mold so that the fiber cloth coincides with the outer surface of the mold and forms a three-dimensional fiber cover;
[0062] S15B, the short fibers on the mesh tire are driven to combine with the three-dimensional fiber cover of the laminated unit during the running process away from the mold through a plurality of positive needles arranged on the peripheral side of the needle main body.
[0063] The needles can be arr...
