Embodiment Construction

[0029] Please refer to Figure 1 to Figure 7 Shown, it has shown the concrete structure of preferred embodiment of the present invention, comprises the following steps:

[0030] (1) Prefabricated block foaming powder 10, according to the shape of the required prepared pipe, the foaming powder is made into a block foaming powder 10 with the same shape as the pipe (such as figure 1 shown).

[0031] (2) Wrap a plastic interlayer 20, and wrap at least one plastic film interlayer 20 outside the bulk foam powder 10 (such as figure 2 shown), in this embodiment, the bulk foaming powder 10 is packed into a plastic film bag to form the aforementioned plastic film layer 20 outside the block foaming powder 10, which is not limited thereto.

[0032] (3) Roll the fiber cloth 30, choose the fiber cloth 30 and wrap the fiber cloth 30 around the plastic interlayer 20 to form a semi-finished pipe (such as image 3 shown), in this embodiment, the fiber cloth 30 is made of carbon fiber, but n...

Abstract

A disclosed manufacturing method for fiber tubes comprises the following steps: (1) prefabricating bulk foam powder; (2) coating with a plastic interlayer; (3) reeling fiber cloth; (4) curing molding; and (5) taking out the finished product from a forming die. According to the manufacturing method, a foam powder is used for preparation of the bulk foam powder with a shape identical to the tube shape according to the shape of the tubes; then the plastic interlayer is covered, the fiber cloth is reeled, and curing molding is performed, thus a conventional mode that a fiber tube is filled with foam particles is replaced, so that the bulk foam powder is heated uniformly and expands, and thus an inner pressure is formed from the interior and the fiber cloth is expanded and clings to the inner wall of the die for molding, so that the manufacturing method helps to put an end to sand inclusion caused by the easily overflowed foam powder and molding defects comprising fake connection and the like caused by hollow foam powder, and effectively improve molding yield rate; and the manufacturing method is simple to operate and has substantially improved working efficiency.

Description

technical field [0001] The invention relates to the technology in the field of rackets, in particular to a method for manufacturing a fibrous pipe. Background technique [0002] At present, the production method of the known fibrous pipe is: first select the fiber cloth to roll into a hollow fiber pipe; then, put an appropriate amount of foaming powder into the fiber pipe; Put the fiber tube into the forming mold and heat it, so that the fiber tube is solidified and shaped. During the heating process, the foaming powder is heated and expanded to form an internal pressure from the inside, and the fiber cloth is bulged and attached to the inner wall of the mold cavity to be shaped; finally , Take the pipe out of the forming mold. [0003] Although the above-mentioned method can realize the production of fibrous pipes, yet, in the production process using the above-mentioned method, because it uses the foaming powder directly loaded into the fiber pipe, the distribution of the...
