Splicing-free carbon fiber reinforced graphite tube

Technical Field

The utility model relates to the field of machinary, concretely relates to graphite pipe.

Background

Pure graphite tubes are brittle and easily broken, so they are usually not too long.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a no concatenation carbon fiber reinforced graphite pipe to solve above-mentioned technical problem.

The utility model discloses the problem solved can adopt following technical scheme to realize:

the splicing-free carbon fiber reinforced graphite pipe comprises a pipe base body made of tubular pure graphite and is characterized by also comprising strip-shaped carbon fiber cloth, wherein the carbon fiber cloth is spirally wound outside the pipe base body;

Firstly, this patent has coiled carbon cloth outside the graphite tube, and carbon cloth can effectively strengthen tensile, the anti-seismic performance of graphite tube, solves the fragility problem of pure graphite tube, allows the graphite tube to do longer. Secondly, the carbon fiber cloth of this patent has two to inject spiral opposite direction, can further strengthen the tensile, the anti-seismic performance of graphite pipe.

The carbon fiber cloth is preferably twill-woven on two sides and plain-woven inside. The structure of the carbon fiber cloth is optimized, on one hand, the tearing strength of the carbon fiber cloth is higher, and therefore the tensile capacity of the graphite tube is further improved; on the other hand, the friction force between the carbon fiber cloth and the tube base body is increased, and the carbon fiber cloth can be effectively prevented from shifting.

According to the preferred scheme, the two pieces of carbon fiber cloth are respectively a first carbon fiber cloth and a second carbon fiber cloth, and a plurality of staggered points are formed on the surface of the tube substrate by the first carbon fiber cloth and the second carbon fiber cloth;

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further explained with reference to the specific drawings.

Referring to fig. 1, the splicing-free carbon fiber reinforced graphite tube comprises a tube base body 1 made of tubular pure graphite and strip-shaped carbon fiber cloth, wherein the carbon fiber cloth is spirally wound outside the tube base body 1; the two carbon fiber cloth have the same pitch, but the spiral direction is opposite. Firstly, this patent has coiled carbon cloth outside the graphite tube, and carbon cloth can effectively strengthen tensile, the anti-seismic performance of graphite tube, solves the fragility problem of pure graphite tube, allows the graphite tube to do longer. Secondly, the carbon fiber cloth of this patent has two to inject spiral opposite direction, can further strengthen the tensile, the anti-seismic performance of graphite pipe.

Referring to fig. 2, the carbon fiber cloth is preferably a cloth woven with twill weaves on both sides and plain weaves inside. The carbon fiber cloth comprises radial carbon fiber bundles positioned in the radial direction and weft carbon fiber bundles positioned in the weft direction, wherein in the plain weave part, the positions of the radial carbon fiber bundles are changed once when meeting one weft carbon fiber bundle, and the positions of every two radial carbon fiber bundles are changed the same; in the twill weaving part, the positions of the radial carbon fiber bundles change once every two weft carbon fiber bundles, and the positions of the radial carbon fiber bundles change the same every three positions. The structure of the carbon fiber cloth is optimized by combining two weaving modes, on one hand, the tearing strength of the carbon fiber cloth is higher, and the tensile capacity of the graphite tube is further improved; on the other hand, the friction force between the carbon fiber cloth and the tube base body 1 is increased, and the carbon fiber cloth can be effectively prevented from shifting.

The two pieces of carbon fiber cloth are respectively a first carbon fiber cloth 2 and a second carbon fiber cloth 3, and the first carbon fiber cloth 2 and the second carbon fiber cloth 3 form a plurality of staggered points on the surface of the tube matrix 1. The up-down arrangement sequence of the carbon fiber cloth at the staggered points can be completely consistent and can also be staggered with each other. Preferably, the first carbon fiber cloth 2 is arranged above the second carbon fiber cloth 3 at one staggered point, and the second carbon fiber cloth 3 is arranged below the first carbon fiber cloth 2 at the adjacent staggered point. The winding mode is relative to the structure of the winding mode in a single direction, and the carbon fiber cloth is not easy to slip and shift. Moreover, compared with the design that the carbon fiber cloth on the staggered points is arranged in a consistent manner, the problem that the whole carbon fiber cloth is not easy to loosen due to cracking of the carbon fiber cloth is solved.

Thermosetting resin can be sprayed on the outer side wall of the tube base body 1 and the outer surface of the carbon fiber cloth. And forming an outer protective layer after the thermosetting resin is cured. The outer protective layer can fix the carbon fiber cloth on the surface of the tube base body 1 to prevent the carbon fiber cloth from shifting. In addition, the outer protective layer can form a firm force transfer bridge on the outer wall of the tube base body 1, and the strength of the graphite tube is increased.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
