Low Thermal Expansion Light Weight Pultruded Carbon Fiber Tube

A Pultruded Carbon Fiber Tube is a type of carbon fiber composite material that is manufactured using a pultrusion process.

The pultrusion process involves pulling continuous fibers (in this case, made of carbon) through a resin bath and into a heated die, resulting in a continuous and uniform composite profile. This manufacturing process makes Pultruded Carbon Fiber Tubes more durable and lightweight compared to traditional materials.

Pultruded Carbon Fiber Tubes have a high strength-to-weight ratio, are corrosion-resistant, have low thermal expansion values, and are able to withstand high temperatures. They are commonly used in aerospace, automotive, construction, and sporting goods industries, among others. They are ideal for applications where high strength and light weight are critical design factors. The tubes may have various shapes and dimensions, depending on the application they are designed for.

Technical Characteristics of Pultruded Carbon Fiber Tubes:

• High Strength-to-Weight Ratio: Carbon Fiber Tubes offer a high strength-to-weight ratio compared to other materials, making them an excellent choice for lightweight applications that require stiffness and strength.
• Corrosion-Resistant: Pultruded Carbon Fiber Tubes have excellent corrosion resistance, which makes them useful in marine and other outdoor applications.
• Low Thermal Expansion: Carbon Fiber Tubes have a very low coefficient of thermal expansion, which means that they have excellent dimensional stability under changing temperatures.
• High Stiffness: Carbon Fiber is stiffer than steel, but lighter in weight, making it useful for applications that require high stiffness without adding additional weight.
• Bi-Directional Strength: Pultruded Carbon Fiber Tubes offer bi-directional strength, which means that they are strong in both the axial and radial directions.
• High Temperature Resistance: Carbon Fiber Tubes are also resistant to high temperatures and can be used in high-temperature applications without deforming or breaking down.
• Electrical Conductivity: Carbon Fiber is a good electrical conductor, which makes it useful for applications in the electronics industry.
• Good Fatigue Resistance: Carbon Fiber Tubes have good fatigue resistance, which means that they can withstand repeated loading cycles without failing.

These characteristics make Pultruded Carbon Fiber Tubes an excellent choice for a wide range of applications, from aerospace to automotive, sporting goods, and industrial 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.
