800mm Length Clear Epoxy 3K CF Tubes Carbon Fiber Tube Anti Corrosion

Top Performing Carbon Fiber Tubes Lightweight 3K CF Tubes with Strong Clear Epoxy

Lightweight 3K CF Tubes Description:

Our Carbon Fiber tubes are designed for the best strength to weight ratio. We use a full wrap of 3K filament fabric impregnated with strong clear epoxy, then a fine gloss or matte finish is added. There are no fillers! These CF tubes provide a perfect balance between strength, stiffness, and weight. This design creates a very light tube, strong enough for Multi-copter design and their numerous crashes. Also, the twill design prevents damage from twisting the tube, enabling these tubes to handle heavier loads. These tubes are very different from the common "kite" tubes.

Other advantages include handling the pressure of motor blocks, preventing rotation failure, and crushing of the arm material common in multi-copter drone builds.

Discount Pricing for large quantities can be arranged by contacting us. Also, custom CF tubes can be manufactured for our customers when in LARGE quantity. This would include custom O.D., I.D., length, and drilling of needed holes or slots.

What is a 3K Twill Carbon Fiber Tube?

Carbon fibers are known for their high tensile strength (stretch/pull). The threads are very small and are normally bundled together to make a stronger “rope” called a tow. A common tow in this application uses 3000 fibers (called 3K). Even though a tow may contain 3000 carbon fibers it is still small. These tows are woven together in a crisscross pattern to form a very thin fabric sheet.

The term “Twill” refers to the pattern of the weave which is more complex than a simple 1x1 weave pattern. Common twill weaves may include 2x1, 2x2, and 3x1 patterns. These patterns have proven to be stronger than 1x1 weaves.

The manufacturer will use a lightweight clear epoxy to impregnate the weave to hold the carbon fiber in place as it is formed into a round tube. The epoxy adds some strength to the tube, but its main job is to spread the load evenly over all the fibers for maximum durability. Lastly, a very thin spray coat is applied to produce a gloss or matte finish.

(Many “cheap” carbon fiber tubes found online will use material other than carbon, such as fiberglass fibers. Some produce tubes with paper that have a twill pattern on it.)

LIJIN's carbon fiber tubes have been used in high-end drone assemblies, marine and aircraft applications. We are proud to offer simple high-quality products at a discounted price.

How to Cut Carbon Fiber Tubes?

To cut them well Carbon Fiber tubes require the right tools. First, it requires protection for your eyes and a mask to prevent inhaling the carbon dust. It is also recommended to have a vacuum system near the cutting area to reduce the dust in the air. A high-speed cutting tool is best (such as a Dremel tool), use a metal cutting blade. Another useful tool can be a high RPM router with a narrow diamond cutting tip. In both cases, it may be best to mount the tool on a jig and then rotate the tube through the blade.

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.
