Braided Carbon Fiber Square Tubes - Various Sizes - LIJIN Composites

Square Carbon Tube

• Easily mount equipment & hardware to the ID or the OD
• Standard dimensions allow for easy component machining if / when needed
• Radius corners allow for efficient stress transfer plus;

Let's just say it, they're just plain good looking

SQUARE TUBE HIGHLIGHTS:

• Allows for the "clocking" of your product or assembly
• The majority of "Off-Axis" plies allow for a nicely balanced layup. The majority of products contain +/-0° plies and a blend of 90°'s
• Easily mount equipment & hardware to the ID or the OD
• Standard dimensions allow for easy component machining if / when needed
• Radius corners allow for efficient stress transfer plus;

This square tubing is comprised of Carbon Fiber Braid and Unidirectional Fabrics. This product is ideal for building lightweight frames and structures such as trusses. Our Carbon Fiber square tubing has been engineered to be much stronger under torsional and side loading than pultruded tubing.

Our tubing is also significantly lighter than pultruded tubing. Our carbon fiber square tube has been designed so that the unidirectional layers are captured in a sandwich structure, eliminating longitudinal cracking and splitting. The finish on this product is different from our other product lines. These square tubes show the texture of the carbon fiber braid with a wet shiny appearance.

The Square Carbon Fiber Tubes have an outermost layer of 2x2 twill fabric which gives the tube a few advantages including better machinability, reduced splintering, and the decorative aesthetics associated with carbon fiber. All our roll-wrapped tubes feature a slight rib texture spiraling along their length where shrink-tape has been used in the manufacturing process. If need be, this can easily be sanded and polished away.

Upon request, we can manufacturer tubes using intermediate or high-modulus carbon fiber. Custom options also include variations of layers and fiber orientation. Fibers oriented at 90 degrees (hoop) are wrapped around the circumference to provide high crushing strength and stiffness. The fibers that run along the length, in the 0-degree direction, provide high bending strength and stiffness. Fibers oriented at +/- 45 degrees deliver increased torsional rigidity.

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.
