Embodiment 1
[0062] Such as figure 1 As shown, the present embodiment provides a method for manufacturing a composite fuel tank, which mainly includes the following steps:
[0063] 1) forming a first shell, one end of the first shell is open;
[0064]2) forming a second shell, one end of the second shell is open;
[0065] 3) Bonding the open end of the first shell and the open end of the second shell to form a hollow shell, which is the inner shell of the composite oil tank;
[0066] 4) Forming a third shell surrounding the inner shell around the inner shell, the third shell being the outer shell of the composite fuel tank.
[0067] In this embodiment, the first shell and the second shell with one end open to the outside are formed firstly through the molding process, and then the open ends of the first shell and the second shell are bonded to make the first shell, the second shell The casing forms a hollow shell that acts as the inner shell of the composite fuel tank. By molding in th...
Embodiment 2
[0072] This embodiment mainly provides a method for forming a first shell, which includes the following steps:
[0073] 1) Manufacture a first mold for molding the first shell.
[0074] Design the drawing of the first mold according to the shape of the first shell, and establish a three-dimensional solid model. According to the three-dimensional solid model, first prepare a wooden mold, and then paste it according to the glass fiber reinforced plastic mold paste process to obtain the first mold for molding. The FRP female mold of the shell.
[0075] For the preparation of the wood type mold, the whole wood type is prepared first, and then divided into two parts of the wood type after parting, and the two parts of the wood type are made as hollow. After the wood type is prepared, it is necessary to inspect the size, bevel angle, oil pipe boss position, process edge, R angle, demoulding slope, parting surface size, etc. of the wood type. The position of the fuel filler is used...
Embodiment 3
[0084] This embodiment provides a method for manufacturing the second casing, and the specific method includes the following steps:
[0085] 1) Manufacturing a second mold for molding the second housing;
[0086] This step is specifically as follows: firstly, a drawing is designed according to the shape of the second casing, and a three-dimensional solid model is established. Then a second mold is manufactured according to the three-dimensional solid model. The manufacturing method of the second mold can refer to the manufacturing method of the first mold in Implementation 2.
[0087] 2) Forming the second shell by using a vacuum bag forming process;
[0088] For this step, refer to the process of forming the first casing by vacuum bag forming process in Embodiment 2.
