Large carbon fiber tubes with a diameter of more than 300mm are generally manufactured by an automatic winding process. This process is suitable for producing tubes with large diameter, constant wall thickness and long length. The manufacturing process is to wind the pre-impregnated carbon fiber bundles on a cylindrical or conical mold, then cure the resin by heating and curing, and finally take out the mold, and the tube is made. The process has the advantages of fast speed, high degree of automation, stable process and reliable product quality.
The manufacture of large-diameter carbon fiber tubes using the automatic winding process requires the use of a fully automatic CNC winding machine. The machine equipment is composed of control system, winding equipment, curing equipment, automatic cutting equipment and so on. Its winding equipment has cardan shaft, sliding plate, main shaft, winding frame and other parts, and the winding process is completed through motor drive and software control. Curing equipment is the area used to heat and cure prepreg resin. Common curing methods include heating lamps, heating plates, and microwave heating. Automatic cutting equipment is used to cut the manufactured carbon fiber tubes to the required length. This machine equipment has the characteristics of high degree of automation, high production efficiency and stable process. It is one of the main equipments for producing large diameter carbon fiber tubes.
Large carbon fiber tubes are usually used in high-demand fields, mainly including the following aspects:
1. Aerospace Field: They are widely used in the aerospace field to manufacture structural components of aircraft, satellites, rockets, etc., such as fuselage, wings, wingtips, engine bulkheads, satellite antenna brackets, aviation hydraulic system, etc. Its light weight, high strength, high rigidity and corrosion resistance can improve flight performance and economic benefits.
2. Energy Field: They can also be used in energy equipment such as oil drilling platforms, wind turbine blades, offshore wind power towers, hydropower turbines, solar steam generators, etc., and can withstand extreme environmental conditions and high load conditions. work, while having the advantages of reducing structural weight and increasing strength and rigidity.
3. Transportation Field: They are widely used in transportation equipment such as automobiles, trains and ships, such as manufacturing vehicle frames, reinforcing rods, car bodies, hulls, etc. It can reduce vehicle weight, increase strength and corrosion resistance, thereby improving fuel economy and energy saving effect.
4. Construction Field: They can also be used in construction, bridges, tunnels and other fields, such as bridge reinforcement, tunnel lining, building structures, etc. Its high-strength properties can effectively increase the bearing capacity of buildings, reduce the weight of buildings, and thus improve the stability and safety of buildings.
To sum up, large carbon fiber tubes have a wide range of application fields and extremely high application value.
