Embodiment Construction
[0018] see figure 1 A method for designing and manufacturing a honeycomb sandwich structure ventilation channel provided by an embodiment of the present invention includes the following steps:
[0019] Step 1, prepare the honeycomb sandwich structure mold.
[0020] Step 2: Lay the cut prepreg cloth on the honeycomb sandwich structure mold, first lay the bottom layer, then lay the frame, and pre-embed the silicone rubber rope in the frame laying attachment.
[0021] Step 3, performing vacuum pre-curing on the honeycomb sandwich structure mold, and pulling out the silicone rubber rope from the frame.
[0022] Step 4, laying the adhesive film and the aluminum honeycomb on the honeycomb sandwich structure mould.
[0023] Step 5, laying the outer skin on the aluminum honeycomb and the frame, and pre-pressing the convex and concave molds.
[0024] Step 6, drilling holes on the outer skin, cleaning the edge gaps of the honeycomb sandwich structure mold, and vacuuming the honeycomb...
