3K Filament Winding Round Carbon Fiber Pipe High Modulus

High Modulus 3K Light Weight Filament Winding Round Tube Carbon Fiber Pipe

Filament Winding

The filament winding process begins with a tow of carbon fiber, fiberglass, or carbon fiber-fiber glass hybrid. The tow is put on the spools at the winding machine. There is a mandrel that is at the front of the spools. This process involves winding filaments under tension over a rotating mandrel. The mandrel rotates around the spindle while a delivery eye on a carriage traverses horizontally in line with the axis of the rotating mandrel, laying down fibers in the desired pattern or angle. Once the mandrel is covered with the desired thickness, it will be placed in the oven for curing. After the resin is cured, the mandrel is removed, leaving the hollow final product.

With our thin ply tech, multiple thin-layered film construction using CF and AL or selected fiber layer, low FAW CF ply combined with AL foil or selected fiber backing, it is strong and lightweight.

Carbon Fiber Tubes FAQ

1. How is the diameter of your tubes measured?
Except for pultruded tubes (diameter measured from outside), all DragonPlate tube diameters are measured from the inside of the tube (ID). To determine the approximate outside diameter, add 2x the wall thickness to the ID measurement.

2. What finish options do you offer for your tubes?
Finish options include gloss, natural, textured, and tooled, depending on tube type. Please see each tube type for finish options. We also offer a sanded finish upon request. Contact us for more details.

3. How do you recommend cutting DragonPlate carbon fiber tubes? Is there any safety gear that I should use?
DragonPlate carbon fiber tubes are pre-cut to the specified lengths or slightly oversized. The tubes are easily cut to length using a bandsaw, coping saw, or Dremel tool. Recommended precautions include wearing safety glasses, a dust respirator, and protective clothing when cutting, sanding or drilling, to limit exposure to the dust, which is an irritant.

4. Do you offer custom cutting of your carbon fiber tubes?
Yes! We can custom cut our carbon fiber tubes to your specified length. Contact us for details.

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.
