Straight Carbon Fiber Tube, 4" Outer Diameter, Length 11.8 inch (300 mm), 1.5mm Thickness, 3K Twill Real Carbon Fiber

We have been a professional chinese carbon fiber manufacturer and carbon fiber products for over 10 years!

we produce all types of carbon fiber tubes, panels, bars, rods, CNC sheets Etc excellent properties include: corrosion resistance lightness, and good toughness If you want to order our products, please include ID, OD, length, dimensional tolerances, quantity, structural requirements, surface finish, surface pattern, material (if you know), temperature requirements, processing technology, etc. With these items as the starting point, we can quickly provide a quotation to help you get your project from idea to reality.

We produce CFRP pipes with different fiber structures according to your requirements. Our wide range of stock in the dimensions of Ø5mm - Ø210mm offers carbon tubes for different applications - directly from stock. Larger diameters up to Ø500mm and lengths up to 6000mm are available on request. With our carbon precision tubes, we attach great importance to dimensional accuracy and quality. As a manufacturer of carbon tubes, we have matched the tolerances so that our carbon tubes fit together telescopically. In the products area, you will find all stock dimensions of the carbon tubes listed according to wall thickness. You will also find categories in which the carbon tubes are grouped by outer and inner diameter. A filter option is also available here. So you can filter the carbon tubes in each category exactly by diameter. With this option, you have an overview of all carbon composite tubes with exactly the inner or outer diameter you have selected and can thus best decide which carbon tube best suits your application.

Whether your project is big or small, we are bound to have a round composite tubing product that suits your needs. To help you get started on your project right away,

We can also cut your tubes to specific lengths with a variety of tolerances, and for many tubes, we offer sanding services. Whether it's aesthetic variations or superb mechanical properties, we've got the composite tubes for you!

We can create carbon fiber and composite materials in any shape or size, and we work closely with our clients to meet their exact specifications.

The first use of carbon fiber in high performance goes back to 1960-1970. It became popular very quickly in every technical area where lightness and strength were primary requirements.

Carbon fiber originates from thermal pyrolysis in a controlled oven where a material called precursor is strongly warmed up at a temperature of about 2000° C in an inert gas atmosphere to produce graphite.

Then other heat treatments modify the final properties of the fibers, for example warming up at temperatures lower than 2000°C gives you a stronger material, whereas with higher temperatures you'll get a more expensive carbon fiber but with a higher Elastic Modulus (Young's modulus).

This is why today there are many kinds of carbon fibers that, even if they're similar, leads to products with different prices and performances.

The carbon fibers previously obtained are lately drowned in epoxy resin (called the matrix) that acts as a binder, allowing the fibers to work together and to distribute the strain uniformly to each one of them.

As you can guess this matrix has a primary role and it has been studied and improved in the last years, like the nanocomposite fillers inside of it.

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.
