100% Roll Wrapped Carbon Fiber Tube 3K /Tubing Plain Glossy/Matte 3K Glossy Plain

Roll Wrapped Carbon Fiber Tube refers to a type of carbon fiber tube that is made by rolling carbon fiber fabric (pre-impregnated with resin or impregnated during the process) around a mandrel in a controlled manner. This method is called roll wrapping, and it is commonly used to produce high-strength, lightweight tubes for a variety of applications.

Our plain gloss carbon fiber tube is roll-wrapped from unidirectional carbon fiber with a 3k plain glossy carbon fiber fabric outer layer. They not only offer a beautiful surface but also excellent torsional characteristics, as well as crush strength, and are ideal for high torque applications. This round tubing is ideal for building lightweight frames and structures, tubular vessels, poles, column supports, and any other application where low weight and high stiffness are essential and appearance is also important.

Our roll-wrapped carbon fiber round tubes come in various diameters, lengths, and thicknesses, If you want to buy a large-diameter carbon fiber tube or any other specific carbon tube, do not hesitate to contact us, we offer custom carbon fiber tubes for you.

What carbon fiber tubes we supply?

Carbon fiber round tube Is rolled unidirectional carbon fiber fabric into a mandrel, and roll wrapped a 3k plain gloss finish fabric exterior. Unidirectional carbon fiber is the structural backbone of all our tubes, the fabric weave that gives carbon fiber tubes their traditional ”carbon fiber look” is only the outside layer and helps with durability. Usually, any wall thickness can be made by changing the number of layers or combining different prepreg thicknesses (0.15mm- 0.25mm thick per layer), Our tubes typically use layups designed for optimal performance in a wide range of conditions. We use 100% real carbon fiber materials making carbon fiber tubing in a wide variety of diameters and lengths. Common carbon tube diameter includes 4mm carbon fiber tube, 6mm carbon fiber tube, 8mm carbon fiber tube, 10mm carbon fiber tube, ... 30mm carbon fiber tube, our round tube standard length is 1000mm, If you need a carbon fibre tube with other lengths or diameters, or need colored carbon fiber tube, do not hesitate to contact us, we can cut and custom carbon fiber tubes to your specified.

We offer multiple finishes with standard modulus carbon fiber tube offers excellent strength and stiffness, It is 1.5X stiffer than aluminum and is the most economical grade.

Carbon fiber tube properties

• High strength-to-weight and stiffness-to-weight ratios
• Resistance to fatigue
• Dimensional stability due to an extremely low coefficient of thermal expansion (CTE)
• 100% high-quality pure carbon fibre (aka full carbon).
• Pin-hole-free high-gloss cosmetic surface.
• Wide range of diameters and tube lengths available.
• Offer carbon fiber tube cutting service according to your design drawings, Cut to dimensions with CNC machining center – which ensures stable and precise dimensions.

Characteristics of Roll Wrapped Carbon Fiber Tubes:

Manufacturing Process:

• Carbon fiber sheets or tapes are rolled around a cylindrical mandrel (a core or mold) with precise overlap.
• Resin is either pre-impregnated or applied during the process, and then the tube is cured in an oven or autoclave.

Strength and Stiffness:

• These tubes typically have high tensile strength and excellent stiffness due to the layered structure of the fiber.
• The orientation of the fibers can be customized for specific load-bearing requirements, providing strength in targeted directions.

Customization:

• The number of layers, the type of resin, and the fiber orientation can be adjusted to optimize the tube’s properties for a particular application.
• Common options include multiple layers of fiber arranged in different orientations like 0°, 90°, and ±45°.

Lightweight:

• Roll-wrapped carbon fiber tubes are lighter than their metal counterparts while maintaining superior strength and durability.

Applications:

• Roll-wrapped carbon fiber tubes are often used in aerospace, automotive, sporting equipment, robotics, drone frames, and structural components that need to combine strength with minimal weight.

Surface Finish:

• These tubes often have a smooth and shiny finish, which can be aesthetic as well as functional (reducing drag in certain applications).

Typical Uses

Roll wrapped tubes are better for applications where the tube may be subject to a variety of forces including bend, twist and crush. These light 12mm tubes are suitable for demanding engineering applications including scale aircraft, gliders, helicopter U.A.V.’s, lightweight frames or structures, tubular vessels, poles, column supports or any construction that requires strength, rigidity and lightness yet appearance is also important. They are equally suited to other precision applications like robotics and automation.

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
