Durable 3K Roll Wrapped 50mm Carbon Fibre Tube Fatigue Resistant

Small Tolerance Range Durable 3K Roll-Wrapped 50 mm Carbon Fibre Tube

Carbon Fiber Tube Description:

Carbon fibre tubes can be used to replace aluminium or steel tubes in a wide range of projects. The Carbon fibre tube of the same weight as an aluminium or steel tube can be much stronger and lighter. This 10mm 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 exactly 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.

CARBON FIBRE TUBES: STRONG AND RIGID
Carbon fibre tubes are used in various applications over traditional materials such as aluminum, titanium, and steel. This is because of their unique properties such as strength, weight, and rigidity.

WHAT IS CARBON?
Carbon fibre is a strong, stiff, thin fiber of nearly pure carbon, made by various raw materials to high temperatures, combined with synthetic resins to produce a strong, lightweight material used in various constructions.

THE BENEFITS OF CARBON FIBRE TUBES

• High strength and stiffness with low weight
• Excellent fatigue resistance
• Dimensional stability: Low to Zero CTE (Coefficient of Thermal Expansion)
• Extreme low weight
• Easy to use in a big variety of applications

APPLICATIONS FOR CARBON FIBRE TUBES

Due to its versatility, Carbon fibre can be used in a great number of applications. Carbon fibre can be used in industrial markets such as automotive, infrastructural engineering and construction. On the other side are there a lot of opportunities to use carbon fibre in motorsports, the built of yachts and other industries.

Carbon fibre tubes can also be implemented in the construction of lightweight bikes, roofing, sun protectors, and so on. The possible applications of carbon fibre are endless!

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.)

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.
