8mm X 8mm x 1000mm – Pultruded 3K Carbon Fiber Square Tube - Black Matte Finish

Carbon fiber square tubes are gaining widespread recognition for their exceptional properties and versatility across various industries. Here, we explore the key advantages of carbon fiber square tubes and why they are becoming increasingly popular.

LIJIN carbon fiber tubing utilizing advanced Nanotechnology. These lightweight pur carbon fiber tubes are carbon hollow rods with 1mm carbon fiber walls yet extremely strong. Round carbon fiber tubes made of 100% carbon fiber with a glossy finish, Tubes are made from 3K Tow carbon fiber weave, which means each weave group consists of 3000 carbon nanotubes with these tow woven in a weave pattern giving both vertical and horizontal strength. These tubes can have any number of uses including RC cars and planes, projects requiring high strength-to-weight ratios, drones, and more.

Advantages of Carbon Fiber Square Tubes

1. High Strength-to-Weight Ratio

Carbon fiber square tubes offer a remarkable strength-to-weight ratio. They are significantly stronger than traditional metal alternatives like steel or aluminum while being much lighter. This characteristic makes them ideal for applications where weight reduction is critical, such as in aerospace, high-performance vehicles, and sports equipment.

2. Superior Stiffness

Compared to aluminum and other metals, carbon fiber tubes exhibit excellent stiffness. This results in less flexing and better dimensional stability, which is particularly beneficial for precision applications where maintaining shape and structural integrity is essential.

3. Low Thermal Expansion

Carbon fiber has a very low coefficient of thermal expansion. This means that carbon fiber square tubes maintain their dimensions better as temperatures change, providing excellent dimensional stability in varying thermal environments.

4. Vibration Damping

One of the unique advantages of carbon fiber square tubes is their ability to dampen vibrations more effectively than metal tubes. This property reduces resonance issues, making them suitable for applications requiring high stability and reduced noise.

5. Corrosion Resistance

Unlike metal tubes, carbon fiber square tubes are not susceptible to corrosion. They can withstand exposure to harsh chemicals, acids, and alkalis without degrading, which ensures a longer lifespan and reduces maintenance costs.

6. Design Flexibility

Carbon fiber square tubes can be manufactured in a wide range of shapes, sizes, and wall thicknesses to meet specific application needs. This flexibility allows for custom designs that can be optimized for particular performance characteristics.

7. Customizable Properties

By adjusting fiber types, orientations, and manufacturing processes, carbon fiber tubes can be tailored to achieve specific properties such as increased strength, stiffness, or other desired characteristics. This makes them highly versatile for different applications.

8. Aesthetic Appeal

The distinctive woven appearance of carbon fiber is often considered visually attractive. This makes carbon fiber square tubes not only functional but also appealing for products where aesthetics are important.

9. High Temperature Resistance

Carbon fiber materials can withstand high temperatures without significant degradation. This makes carbon fiber square tubes suitable for use in high-temperature environments where traditional materials might fail.

10. Excellent Fatigue Resistance

Carbon fiber square tubes exhibit superior fatigue resistance, meaning they can endure repeated loading and unloading cycles without suffering from fatigue failure. This is critical for components that experience constant motion or stress.

The unique combination of high strength, low weight, superior stiffness, low thermal expansion, vibration damping, corrosion resistance, design flexibility, and aesthetic appeal makes carbon fiber square tubes an excellent choice for a wide range of applications. While they may be more expensive than traditional metal alternatives, their performance benefits often justify the investment, particularly in high-performance and precision applications.

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.
