specific Embodiment approach 1
[0039] Specific implementation mode 1: A fiber winding molding method for a tubeless body and oblate ellipsoidal pressure vessel according to this embodiment, the specific winding molding steps are as follows:
[0040] Step 1. Install the mold:
[0041] Fix and set the sand core mold for winding the cylinderless and oblate ellipsoidal pressure vessel on the metal shaft, and then install the metal shaft on the spherical winding machine;
[0042] Step 2. Coating the lining layer:
[0043] Cover the rubber sheet lining layer manually on the surface of the sand core mold, and the thickness of the rubber sheet lining layer is 0.8-2mm;
[0044] Step 3. Paste high silica fiber cloth on the outer surface of the inner lining layer:
[0045] Soak the high silica fiber cloth with epoxy resin winding glue, paste it on the outer surface of the inner lining, the thickness of the high silica fiber cloth is 0.06mm;
[0046] Step 4. Set the spherical winding program:
[0047] Install the c...
specific Embodiment approach 2
[0072] Embodiment 2: The epoxy resin wrapping glue of this embodiment is prepared from epoxy resin and curing agent in a weight ratio of 100:86. Such a setting is convenient for ensuring a more stable work of the mechanism. Other compositions and connections are the same as in the first embodiment.
specific Embodiment approach 3
[0073] Specific implementation method three: the step-by-step reaming spherical winding carried out on the spherical winding machine in step ten of this embodiment, set the spherical winding program: install the carbon fiber on the fiber tensioner, and the winding angle is 25°, 40°, 55° ° or 70°, the winding speed ratio is 0.0057-0.02, the hole expansion radius is 30-250mm, and the carbon fiber covers the entire winding mold to form a winding cycle. With such setting, the design of the structural parameters of the straight spring is very simple, the price is cheap, the weight is light, and the processing difficulty is very low. It is convenient to change the variation range of the resistance provided by changing the spring parameters. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.
