Abstract
The invention discloses a carbon fiber tube. The carbon fiber tube comprises a cylindrical tube body. The carbon fiber tube is characterized in that the tube body is a carbon fiber tube body, wherein a metal inner wall is arranged on the inner side of the tube body, a plurality of spiral-line reinforcing ribs are arranged on the outer side of the tube body, are parallel with one another and are equidistantly and uniformly distributed. The carbon fiber tube has the beneficial effects that the strengthening effects of the spiral-line reinforcing ribs are better than the strengthening effect of a linear reinforcing rib, so that the strength of the carbon fiber tube is improved; the reinforcing ribs with triangular cross sections can play reinforcing effects, the material is saved, and meanwhile, the machining is facilitated.
Description
Technical field
The present invention relates to a kind of composite material tube, be specifically related to a kind of carbon fiber pipe.
Background technology
Carbon fiber has the characteristics such as high strength, high-modulus, high temperature resistant, corrosion-resistant, endurance, creep resistant, conduction, heat transfer, belongs to typical new high-tech product.Aerospace, sports goods field, industrial circle, traffic and transport field and civil construction field are widely used in.
In machining, also extensively adopt carbon fiber pipe alternative metals pipe at present, reach and reduce the object such as machine own wt, raising intensity.But current carbon fiber pipe, reinforcement mostly is the reinforcement paralleling to the axis, and structure is single, and stiffening effect is general.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide the better carbon fiber pipe of a kind of stiffening effect.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of carbon fiber pipe, comprise columniform pipe shaft, it is characterized in that, above-mentioned pipe shaft is carbon fiber pipe shaft, above-mentioned pipe shaft inner side is provided with metal inner surface, above-mentioned pipe shaft outside is provided with many helixes and strengthens convex tendon, and many above-mentioned helixes are strengthened convex tendon and are parallel to each other, and every above-mentioned helix is strengthened convex tendon and is equidistantly uniformly distributed.
Further, the helical angle of above-mentioned helix reinforcement convex tendon is 45 ° ~ 60 °.
Further, the cross section of above-mentioned reinforcement convex tendon is triangle.
Further, the cross section of above-mentioned reinforcement convex tendon is isosceles triangle.
Further, the higher primary school of the cross section of every above-mentioned reinforcement convex tendon is in the length on base.
Usefulness of the present invention is: helix reinforcement is better than the stiffening effect of the reinforcement of straight line, has more improved the intensity of carbon fiber pipe.Cross section is that leg-of-mutton reinforcement not only can play booster action but also saves material, simultaneously convenient processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is cutaway view of the present invention.
The implication of Reference numeral in figure:
10-pipe shaft, 11-metal inner surface, 12-reinforcement.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of carbon fiber pipe as shown in Figure 1 and Figure 2, comprise columniform pipe shaft 10, pipe shaft 10 is carbon fiber pipe shaft, pipe shaft 10 inner sides are provided with metal inner surface 11, pipe shaft 10 outsides are provided with many helixes and strengthen convex tendon 12, many helixes are strengthened convex tendon and are parallel to each other, and every helix is strengthened convex tendon 12 and is equidistantly uniformly distributed, and the distance between every helix reinforcement convex tendon 12 equals the helix reinforcement convex tendon 12 of 1.5 times to 2 times and the width of pipe shaft 10 contact positions.Metal inner surface 11 adopts aluminum pipe and carbon fiber pipe shaft to fit tightly.The quality of aluminium is light, and the carbon fiber pipe shaft in outside can be gained in strength.
The helical angle that helix is strengthened convex tendon 12 is 45 ° ~ 60 °.As shown in Figure 2, the cross section of helix reinforcement convex tendon 12 is triangle.As a kind of preferred version, the cross section that helix is strengthened convex tendon 12 is isosceles triangle, easy to process like this.
For the height that guarantees helix reinforcement convex tendon 12 projections can be not too high, highly too high easy damage.Every helix is strengthened the higher primary school of cross section of convex tendon 12 in the length on base, and the intensity of the reinforcement convex tendon that base the is grown reinforcement convex tendon shorter than base is high.Distance between every helix reinforcement convex tendon 12 is 2 ~ 3 times of base length.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
Claims (5)
