High Quality Carbon Fibre Pultruded Tube Custom 30mm 40mm 50mm 60mm

Pultruded carbon tubes are created by pulling linearly-oriented carbon fibers through a resin bath and then a series of tooling to create the specified inner and outer diameters of the tube. The carbon tube is then heated to cure it. Carbon tubes are especially stiff longitudinally, due to the unidirectional orientation of the fibers.

What is pultruded carbon fiber?

Our Carbon Fiber Pultruded Tubes are manufactured by pulling continuous carbon fibers combined with a resin matrix through a heated steel forming die. This process is referred to as pultrusion and is used for producing continuous lengths of composite materials with constant cross-sections.

What is the strength of carbon fiber pultrusion?

Tensile Strength: 250 ksi | 1.72 GPa. Tensile Modulus: 20 msi | 138 GPa. Ultimate Shear Strength: 6.0 ksi | 41.3 Mpa.

How do you safely cut carbon fiber tubes?

When cutting composites, it is ideal to use a diamond coated abrasive cut-off blade rather than a toothed blade. Teeth can catch the fibers and tear the material resulting in splintering or delamination. Thicker tubes may generate enough heat to re-activate the epoxy causing the blade to “gum-up”.

Can carbon fiber tube be threaded?

The Threaded Tube Insert component is used to attach additional parts to the truss structure off the end of a tube. The tube end insert is bonded securely into the end of a carbon fiber tube and provides a means to thread bolts or other parts with mating threads into the tube ends.

Are carbon fiber tubes strong?

Carbon fiber tubes are used in numerous applications like tactical ladders, trusses, beams, and more. Carbon fiber is typically chosen over traditional materials such as aluminum, steel, and titanium because of the following properties: High strength and stiffness to weight.

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.
