Embodiment Construction

[0027] Such as figure 1 Shown, the present invention relates to a kind of preparation method of ultra-large composite carbon fiber tube comprising the following steps:

[0028] Step 1: Make the mold.

[0029] Such as image 3 As shown, the mold is composed of a mold skeleton 2 and a mold skin 3 . The mold skeleton 2 is welded and spliced ​​by the metal skeleton, which is simple in forming and high in strength, and can meet the requirements of making carbon fiber tubes of any diameter. The mold skin 3 is fixed on the mold skeleton 2, and the mold skin 3 is riveted with the metal skeleton 2.

[0030] Apply mold release agent on the outer surface of the mold skin, fill the splicing gap of the mold skin with unsaturated resin putty, and polish to ensure the surface of the mold skin is smooth. The mold skin is made of rolled steel plate, and the mold skin is composed of 6-10 modules, which are spliced ​​together along the circumferential direction, such as figure 2 As shown, ...
