Abstract

The utility model discloses a novel carbon fiber composite tube comprising a hollow tube body. The utility model is characterized in that the inner layer of the tube body is an aluminum alloy layer, and the outer layer is a carbon fiber layer solidified on the aluminum alloy layer. The utility model has the advantages of that it has low weight, high intensity, convenient to carry, and has a long service life. Further, it can effectively ensure the mechanical properties of the carbon fiber, and has low manufacturing cost and easy manufacturing process.

Description

A kind of novel carbon fiber composite pipe

Affiliated technical field

The utility model relates to a kind of mechanical structure accessory, relates in particular to a kind of employed pipe fitting of portable equipment that is used for.

Background technique

At present, the personal portable equipment that is occurred on the market, especially the accessory that needs the portable personal equipment that carries in the outdoor activities is as camera crane, skiing rod etc., for the aluminum alloy manufacturing forms, because the aluminum alloy rigidity is relatively low, for reaching the usage requirement of product, product needed is made thicker also just heavierly, for the user, especially there is the problem of carrying inconvenience in outdoor user.

In light weight by the tubing that the pure carbon fiber pipe is made, intensity is high, easy to carry, long service life, but pure carbon fiber pipe cost height and uses the mould of not reproducible utilization, has increased cost of production and technological process.

Summary of the invention

The utility model provides a kind of novel carbon fiber composite pipe, and its purpose is, overcomes the prior art shortcoming, provides a kind of in light weight, and the intensity height is easy to carry, the employed pipe fitting of portable equipment of long service life.Another purpose of the present utility model is: provide a kind of carbon fiber that can guarantee to give full play to the carbon fibre pipe fitting of mechanical property.Another purpose of the present utility model is to provide a kind of cost of production the low and simple carbon fibre pipe fitting of technology.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of novel carbon fiber composite pipe, it is a hollow tube, it is characterized in that: the body internal layer is an aluminium alloy layer, and is outer for being solidificated in the carbon fiber layer on the aluminium alloy layer.

The beneficial effects of the utility model are: parameters such as carbon fiber pipe tensile modulus and tensile strength all are better than aluminum alloy greatly, advantages such as therefore with the carbon fibre pipe fitting to be that portable device pipes such as the tripod made of basis, walking stick, crutch, ski pole have in light weight, intensity is high, easy to carry, long service life.Carbon fiber is that monofilament diameter only is 7 microns, every synnema number is that the 500-20000 root does not wait, with the pipe fitting intensity height that carbon fiber bundle is made, be other fiber or material can't replace, therefore, carbon fiber is used for decorative appearance same distinguished excellent properties equally.Because the utility model internal layer is an aluminium alloy layer, skin is a carbon fiber layer, has therefore not only kept the various advantages of carbon fiber pipe, reduces cost greatly than pure carbon fiber tube side case again.The aluminium alloy layer of internal layer can play the effect of mould, and making when producing the utility model no longer needs special mould, has reduced cost of production and operation, and technology is simpler.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model radial cross-section.

Embodiment

As shown in Figure 1, the utility model is a hollow tube 1, and internal layer is an Al-alloy pipe 100, and is outer for being solidificated in the carbon fiber pipe 101 of Al-alloy pipe more than 100.

Take following method to make above-mentioned carbon fiber threaded pipe.

1, makes Al-alloy pipe 100, make it to meet the requirements of internal diameter precision and the requirement of straight degree.

2, be the main material of producing with adopting carbon fiber or carbon fibre cloth, the material thickness and the number of plies are according to the body THICKNESS CALCULATION.

3, material adopts resin to guarantee that curing is normal in above-mentioned 2 steps.

4, it is stand-by to require to design the consumption of step 2 prong material and fiber array direction and blanking according to the mechanics of body 1 and weight.

5, the material that step 2 is descended to get well on the work board twists on the Al-alloy pipe 100 and guarantees to roll up closely.

6, outside the pipe spooled is on board, twines the PP plastic tape and guarantee the tape wrap even tension.

The batch pipe that 7, will twine is together put into baking oven and is made it fully to solidify by resin solidification technology.

8, back processing, polishing and cutting make outer electrical path length reach conditions such as external diameter required precision.

Claims

1. novel carbon fiber composite pipe, it is a hollow tube, it is characterized in that: the body internal layer is an aluminium alloy layer, and is outer for being solidificated in the carbon fiber layer on the aluminium alloy layer.
