CFRP Gloss Finish Twill Weave Carbon Fiber Pipes Chemical Resistance

High Performance Twill Weave Gloss Finish Carbon Fiber Roll Wrapped Tube

Carbon Fiber Roll Wrapped Tube Description:

Roll Wrapped Carbon Fiber Tube Twill Weave Gloss Finish uses high strength unidirectional equivalent carbon fiber core with an epoxy resin system to ensure a strong rigid tube that will meet your needs. In addition to this high-strength uni core, this tube is finished with a beautiful 2x2 twill weave carbon fiber and then given a gloss finish. Due to raw material constraints, it is hard to create pipes exactly at a specific measurement unless they are built over-sized and machined down so that is why our pipes may be a few thousandths off from the ideal measurement we are trying to match.

Features:

• Lightweight: Carbon fiber is 5 times lighter than steel (ASTM-A1008) and almost 2 times lighter than aluminum when comparing similar-sized pieces.
• High Strength & Stiffness: Carbon fiber reinforced polymer (CFRP) has the highest specific strength and modulus (stiffness) per density compared to metal, plastic, and wood.
• Resistance to Corrosion & Chemicals: The epoxy resin is inert and not susceptible to corrosion or rust, and the carbon bonds in the fibers are extremely strong and resistant to oxidization.
• Low Thermal Expansion: When metal is exposed to heat, it will expand and weaken which can cause issues and possible failure of the part. Carbon fiber has low thermal expansion.
• Low Thermal Conductivity: Metal acts as a conductor, steel more than aluminum, which can transmit or radiate heat to its surroundings and cause heat soak. Carbon fiber has low thermal conductivity.
• RF Shielding: Carbon Fiber works well to attenuate, or block radiofrequency waves, protecting your devices from scanners or people trying to access your data.

Specifications:

The first use of carbon fiber in high performances goes back to 1960-1970. It became popular very quickly in every technical area where lightness and strenght 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 more strenght 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, allowding 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.

So the carbon fibers drowned in the matrix become to all intents and purposes a composite material like the reinforced concrete, where the final mechanical features are higher than the ones of the constituents materials.

To print a tube with these materials today there are different technologies and each has advantages and disadvantages, but certainly, the wrapping process used by our company is the process with the best mechanical results. In fact, unlike other techniques allows you to have exactly all the fibers at 0 degrees or 90 degrees to the axis, and also to control the amount of resin in the product. For example, this would be very very difficult with the technique of filament winding.

So our composite carbon tubes and rollers use the best technology and materials existent nowadays to get incomparable results from other materials.

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.
