OEM Tubes 3K Roll-Wrapped Carbon Fiber Tube Carbon Fiber Pipe Tube

Carbon fibre tubes can be used to replace aluminum or steel tubes in a wide range of projects. A carbon fibre tube of the same weight as an aluminum or steel tube can be much stronger and lighter. This roll-wrapped carbon fibre tube is manufactured predominantly using high modulus (T700) unidirectional prepreg carbon fibre oriented to provide maximum strength in the lateral axis.

Roll wrapped carbon fibre tubes offer superior strength in general use to ‘pultruded’ tubes (which have all their fibres running in the same direction.

The use of unidirectional fibres and maximum strength in the lateral axis does mean that the tube is not strong across its diameter as it is along its length so should be used in such a way as to avoid unnecessary crushing forces across the tube.

Roll Wrapping:

The phrase ‘roll wrapped’ refers to the process used to manufacture these tubes. The prepreg carbon fibre is first laid up around a mandrel in multiple layers. Once the reinforcement is in place it is spiral-wrapped with heat-shrink tape before the whole assembly is oven-cured.

Characteristics:

Lightweight, excellent corrosion and heat resistance, and electrical conductivity. Very good flexural and hoop stiffness. After laminating, the wound CFK round tubes are ground (round) to size and then coated.

Tolerances:

Deviation in diameter ± 0.2 mm. Deviation in straightness max. 2 mm/m. The measured values are generally far below the maximum.

What are carbon fiber tubes used for?

Carbon fiber tubes are used in a wide range of applications, including tactical ladders, systems, rods, and beams. Carbon fiber provides low weight, and better mechanical properties over conventional materials like aluminum, and steel.

Are carbon fiber tubes strong?

Carbon fiber tubes are used in numerous applications like tactical ladders, trusses, beams, and more. Carbon fiber is typically chosen over traditional materials such as aluminum, steel, and titanium because of the following properties: High strength and stiffness to weight.

Do carbon fiber tubes bend?

Our carbon fiber tubing is built using a thermoset epoxy resin. This means that once cured the epoxy never returns to a liquid state. If you tried to bend our tubing it would break with enough applied force but it will not bend. Carbon fiber/epoxy composite is very stiff!

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.
