Extremely Strong Rectangular Carbon Fiber Tube Low Thermal Expansion

Extremely Strong and Durable Rectangular Carbon Fiber Tube - Low Thermal Expansion

To meet growing market demand, LIJIN is now selling an Economy line of tubes and plates. These products provide a lower bar for entry for customers looking to incorporate carbon fiber and other composites into their projects. This low-cost line is sourced internationally and is best utilized in applications that do not have engineering critical features, but have the convenience of shipping from our Utah operation for expedient delivery.

Our premium tubes and plates are manufactured to our exacting standards in-house. The result is greater strength and stiffness with guaranteed consistent layups, tolerances, and test results. If you need help deciding what is right for you, please contact us and we’ll assist you as best we can.

Unlike metals which have similar properties in all directions (isotropic), the properties of composites are varying, dependent on the orientation of the fibers in each layer. This particular carbon fiber fabric tube has an internal diameter (ID) of 0.25" and an outer diameter (OD) of 0.378". The outer ply of material on this tube is a 2x2 twill weave (diagonal appearance seen below) which will prevent fiber breakout better than unidirectional material. Thus, fabric tubes provide an ideal surface for machining. The core of this tube is almost always comprised of multi-directional "uni" plies which makes most carbon fiber fabric & unidirectional tubes ideal for bending and compression applications.

Key Features

• Exceptionally rigid
• High dimensional stability and UV resistant
• High Corrosion Resistance
• High Thermal Conductivity in some forms
• Very Low thermal expansion (Approx. 8 times lower than steel, 11 lower than aluminium)

What We Manufacture

• We specialize in Carbon Fiber roll wrapped tubes, Pultruded Carbon Fiber tubes, and Pultruded Carbon Fiber rods.
• Our products are available in varying dimensions and can also be customized as per requirements.
• We produce hollow tubes starting from 4 mm to 25 mm in diameter, in desired wall thickness.
• We produce carbon fiber rods starting from 1mm to 25 mm diameters.

Carbon Fiber Customized Pultruded Profiles

The Carbon Fiber pultruded profiles are available in varying sizes and shapes. LIJIN Composites is capable of supplying customized carbon fiber products in line with customers’ specific requirements. With the right product design, development team, and in-house manufacturing facility, we can easily cater to carbon fiber pultruded profiles to meet the most demanding industry specifications. Our pultruded components are easy to work with. They can be cut with a band saw, coping saw, scroll saw, end mill, or Dremel tool.

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.
