Karbon fiber tube is also known as carbon tube. Carbon fiber tube is made of carbon fiber composite pre-impregnated phenethyl polyurethane resin by heating curing pultrusion or winding, carbon fiber has high strength, low density, long life and other characteristics, simply put, lighter than aluminer, harder than steel, is a good civil material.
The mechanical pin of carbon fiber tube is determined by the carbon fiber content, higher content means the better mechanical properties, on the contrary, the mechanical properties are lower. The strength of carbon fiber pipe is 6-12 times that of steel pipe, and it can reach more than 3000MPa. Kecil ketumpatan, ringan berat, ketumpatan is less than 1/4 of steel, widely used in kites, aviation model aircraft, lamp brackets, PC equipment hinges, etching machines, medical equipment, sports equipment and other mechanical equipment. Carbon fiber round tube with stable dimensional, electrical conductivity, thermal conductivity, small coefficient of thermal expansion, self-lubrication and energy absorption shock rintangan - siri daripada cemerlang prestasi.
Karbon fiber tube is mostly made by wrapping process, first according to the specifications of the required pipe to cut the carbon fiber prepreg and select the appropriate pseudo-core mold, and then use the temperature of the reel machine to soften the carbon fiber prepreg, and then evenly roll it to the inner core mold. The control of the dimensional accuracy of the pipe should first consider the mold, and the selection principle of the core mold is to use an elastic material with a large linear amine expansion coefficient as a forming mold, and steel with a small linear expansion coefficient as an auxiliary mold.
In the rolling process, a reasonable ply angle can optimize the mechanical properties, and the common ply angles are 0 degree , ±45 degree , 90 degree . When all the prepreg is rolled, it is coated with an OPP tape and finally sent to an autoclave to cure at high temperature. After molding, the OPP tape is removed to obtain the coarse return of the carbon fiber tube. The unsmooth and flat parts are cut off at both ends, and the polishing and polishing are carried out through multiple processes. The preliminarily completed carbon fiber tube also needs further processing, first according to the specifications of the finished product, the excess parts at both ends of the semi-finished product are removed to form a unified and neat cutting surface, and then after professional grinders and manual sanding and polishing, in order to form a smooth and glossy surface.
With the lightweight effect of carbon fiber round tube in practical applications, carbon fiber rollers in printing, papermaking, plastics, film, textile, cone battery pole winding machines and other industries have also begun to gradually replace traditional metal pipes.
