High Pressure Resistance Flexibility Pultruded Round Carbon Fiber Tubes

3K Pultruded Carbon Tube, can be designed and customized according to customers' requirements, only tailor-made products for customers, welcome to call us for more information. It is ideal for applications requiring the highest bending stiffness and lowest weight. The surface of our tubes can be glossy or matte.

3k Carbon Fiber Tube is a carbon fiber composite material synthesized with 3K small tow carbon fiber and resin material, which is cured and molded through a series of processes. From the perspective of appearance alone, the 3K carbon fiber tube has special textures, such as horizontal grain, twill, satin, etc., which is the effect of carbon fiber filament after weaving.

Features

• Very Strong for its Weight: The 3K carbon fiber's arrangement of 3,000 filaments in each tow provides exceptional strength while maintaining a lightweight profile. This property is crucial in industries where weight reduction is essential, such as the aerospace and automotive sectors.
• Very Rigid and Firm: The aligned fibers provide high stiffness, ensuring minimal deflection under load. This property makes them ideal for applications that require rigidity and stability, such as robotics and industrial equipment.
• Long Life: Carbon fiber composites, including 3K carbon fiber tubing, exhibit excellent resistance to corrosion and fatigue, making them suitable for outdoor and demanding environments.

Q: How strong is a 3K Carbon Fiber Tube?

A: A 3K Carbon Fiber Tube is exceptionally strong, with tensile strengths surpassing 200 GPa (gigapascals). This enables it to withstand immense stress and force before failure. Its strength primarily comes from tightly woven carbon fibers that provide optimal reinforcement. These fibers are further enhanced by a resilient resin matrix, ensuring additional strength and rigidity for the tube.

Q: Are there any limitations to the use of 3K Carbon Fiber Tubes?

A: While 3K Carbon Fiber Tubes offer several advantages, there are also limitations to consider. Firstly, they are more expensive to produce compared to traditional materials like aluminum or steel, primarily due to the cost of carbon fiber fabric and resin. Secondly, repairing them can be challenging because the fibers are integrated into the resin matrix, making it difficult to replace individual fibers if damaged. Lastly, they can be brittle under certain conditions, such as high impact or stress, potentially resulting in cracking or fracturing.

Shanghai Lijin focuses on the Carbon Fiber industry and offers carbon fiber tubes, plates, and aluminum CNC services.

Being experienced in the carbon fiber applications for over 7 years, Shanghai Lijin manages customized production according to various industry standards. Shanghai Lijin started to keep in stock for some standard

sized and frequently ordered tubes and plates. This enables Shanghai Lijin to make prompt delivery. Not only

can Shanghai Lijin complete mass production orders in short period, we can even ship normal sample, prototype orders of Carbon Fiber Plate CNC parts in just SEVEN days after order confirmation when the

drawings are available. Shanghai Lijin is dedicated to solve any technical points during the production and new item developing to ensure the quality.

Carbon Fiber tube production is Shanghai Lijin’s core business and occupies 70% of our turnover.
The carbon fiber tubes Shanghai Lijin mainly produce is table-rolled and oven thermoset. The tubes can be Full Carbon or Carbon Fiber and Fiberglass composite, depending on the application, weight limit,mechanical

strength and surface requirement.Shanghai Lijin offers top quality ROUND carbon fiber tubes. The general OD tolerance we achieve is +/-0.10mm and it can be even +/-0.05mm after our special surface process.

The maximum length of the tube can be 5500mm.

Besides the traditional table-rolled carbon fiber tubes, Shanghai Lijin also offers REAL Filament wound carbon fiber tubes,which are widely used for mechanical strength like auto driving shaft, antennas, even for military

applications. The filament wound carbon tubes are wound at a certain angle like 30 or 45 degree. We invested the new production line from Jun 2013 and this increases Shanghai Lijin’s advantage in the carbon

fiber tube industry. There are just a few real filament wound carbon fiber tube manufacturers in domestic

China and we are one of them.
 

Since the rapid growth of UAV in the international market, instead of the standard plane like Phantom from DJI, RC fans are getting more interested in the customized multicopters. As carbon fiber is the most preferred

material for UAV, Carbon Fiber CNC parts demand is increasing. Shanghai Lijin sticks to offering OEM service for the international market, fine quality and prompt delivery.To ensure the thickness tolerance +/-0.10mm and minimum warp of the Carbon Fiber plates that are used for the cutting, Shanghai lijin execute high standard to

the plate production. For the normal thicknesses including 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm,
Shanghai Lijin keeps regular stock, to make sure the raw material will be available for cutting immediately when order is firmed.Experienced engineers are in Shanghai Lijin’s office ready to deal with different types of

drawings from customers. No matter the drawing formats are .DWG, .DXF that can be edited by AutoCAD

and used directly for production, 3D drawings like .IGS, or even draft drawings, our staff can do adjustment and change to customer’s idea. Our engineers are also good at English communication, Email and IM is easy

for them. Editing drawings for customers is FREE* of charge. Shanghai Lijin is having several professional CNC machines for carbon fiber cutting and drilling, with the capacity of cutting 20-50pcs standard full sized plate per day. The carbon fiber chassis general cutting tolerance Shanghai Lijin offer is +/-0.02mm. The

special designed cutting solution ensures the smoothness of the cutting edge.

‘Customers’ Persuit for Change, Lijin’s Motivation for Growth’, Shanghai Lijin takes customers’ demand for center, enhances the
customer satisfaction, and grows with customer.
