Corrosion Resistance Durable Carbon Fibre Tubes Wound 0°/90°, Plain Weave (3k)

Our goal is to help our customers accomplish their project goals. We promise to provide high-quality carbon fiber tubing and helpful advice on how to integrate our tubing into your project.

What layup is used in these tubes and how strong are they? All of our small tubes are laid up with most of the layers/fibers running axially down the length of the tube. This means that our tubes will display most of their stiffness in bending. All of our small tubes are laid up using uni-directional carbon fiber prepreg. With uni-directional carbon fiber you can design in stiffness exactly where you want it. Using a woven carbon fabric isn't an option when you're designing a tube with the best mechanical properties (stiffness/weight ratio). A major benefit to using composites tubing versus metal tubing is not only the weight savings but the ability to design stiffness where you want it as opposed to a metal tube where the only thing you can do is add wall thickness and weight. Most of our small tubes feature a layer of prepreg glass at both ends which offers some torsional (twisting) stiffness. Many carbon fiber tubes on the market are pultruded. Pultruded tubes are much less expensive and there is a reason for that. The mandrel and the carbon filaments are pulled through a machine and cured at the same time. The downside is that you get very little torsional value from a classic pultruded tube since all of the fibers run in one direction. In real-world situations, this can be a detriment because the slightest twist under loading can split the tube. Also, pultruded tubes are typically heavier (more resin-rich) which degrades the stiffness. More fiber and less resin are always best. All of our tubes are roll wrapped to avoid these problems. As the old saying goes "you get what you pay for". It is important to note that we refer to classic pultruding in the above text. With a pultrusion process called pull-winding, it is possible to include a nonaxial fiber orientation around the diameter of the tube. Pull winding is an automated process that runs continuously and reduces the per-unit cost but also has high start-up costs compared to roll-wrapped tubing. Pull wound tubing is not generally available off the shelf but instead is typically used in proprietary products.

We do not offer specific load ratings for our tubes for several reasons. The first reason is that there are so many ways to load a tube that any loading data we distributed would not be useful. We offer basic information on our material properties page to calculate how a given tube might perform under your loading scenario. The next reason is legal liability. Some applications may involve a threat to life and limb. Since we cannot control how our tubes are used and what safety factors are held to for a given application we do not quote any load ratings for our tubing.

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.
