High Stiffest Roll Wrapped Carbon Fibre Tube 100% 3K Carbon Fiber Tube

Roll Wrapped Carbon Fibre Tube

The tubes in this category are roll-wrapped pre-preg reinforcement. Roll wrapped tubes feature multi-axial orientation of the carbon fibres which gives them more uniformly distributed strength ideally suited to more demanding 'real world' applications where load and forces are rarely in only one direction. Typical uses include mast poles, spinnakers, booms, structural racking and many other medium to heavy duty applications.

We stock Carbon Fibre tube manufactured using 3k plain weave style of Carbon Fibre Cloth Fabric. Plain weave carbon fibre fabric is the 2nd most commonly used type of carbon cloth. Instead of having the distinctive diagonal pattern of 2/2 twill, plain weave is woven over-one-under-one leaving it with a simple grid pattern appearance.

Roll-wrapped tubes feature a slight rib texture spiralling along their length where shrink-tape has been used in the manufacturing process. If needs be, this can easily be sanded and polished away.

Carbon fibre tubes are a rigid carbon fibre product. They cannot be bent or reshaped in any way.

Manufacture of Carbon fibre Products

The primary element of CFRP is a carbon filament made by heating rayon or polyacrylonitrile fibres or petroleum residues to appropriate temperatures. Fibres may be 7 to 8 microns in diameter and are more that 90% carbonized. These fibres are the stiffest and strongest reinforcing fibres for polymer composites.

Carbon Fibre Cloth: From the elementary fibre, a bi-directional woven sheet can be created, i.e. a twill with a 2/2 weave. These sheets may be layered onto each other in a quasi-isotropic layup, e.g. 0, +60 or -60 degrees relative to each other. Depending on the orientation of the fibres, the carbon fibre composite can be stronger in a certain direction or equally strong in all directions. A small piece can withstand an impact of many tons and still deform minimally. The complex interwoven nature of the fibre makes it very difficult to break.

Roll Wrapping: involves the applying of resin pre-impregnated composite fibre cloth (Pre-Preg) around a mandrel. The outer diameter of the mandrel thus determines the inner diameter of the final tube. The mandrel and cloth are then spiral wrapped with a consolidation tape under tension to hold the laminate in place during the curing phase. After curing, the mandrel is extracted to leave the tube ready for machining or finishing as necessary.

Pultrusion: is a process in which dry, continuous fibres are pulled through a bath of resin and then through a die. The die serves two purposes: it forces the bundle of wet fibres to conform to the shape you want to create and, since the die is heated, it will cure the resin to set the bundle of fibres into its final shape. After the composite comes out of the die, it is allowed to post-cure while being pulled to the saw where it will be cut to stock lengths.

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.
