Anti Ultraviolet Radiation Carbon Fiber Tubing Good Toughness Unidirectional

Anti-Ultraviolet Radiation Good Toughness Unidirectional Carbon Fiber Tubing

This is the workhorse of our carbon fiber tubing products. The majority of our unidirectional tubes are comprised of 0° and 90-degree plies with an occasional layup deploying ±45° plies, but we also offer pultruded uni tubes. While almost all of our roll-wrapped tubes have underlying layers of unidirectional carbon fiber, this carbon tubing product line has the outermost layer of unidirectional fiber instead of a woven fabric. We offer cutting and sanding services for most of our tubes. NOTE: Generally 10 plies of a standard modulus fiber = a wall thickness of 0.060".

What is unidirectional carbon fiber?

Unidirectional carbon fiber fabric is a type of carbon reinforcement that is non-woven and features all fibers running in a single, parallel direction. With this style of fabric, there are no gaps between fibers, and those fibers lay flat.

What is the difference between unidirectional and bidirectional fiber?

A unidirectional optical fiber cable can only transmit data in one direction, either from the transmitter to the receiver or from the receiver to the transmitter. In contrast, a bidirectional optical fiber cable can transmit data in both directions simultaneously, using different wavelengths of light.

Is carbon fiber directional?

For an easy analogy, think of a piece of wood. The strength of wood is dependent on the orientation of the grain. This is true with carbon fiber – the strength of the carbon fiber is dependent on the orientation of the fiber (grain).

What are the advantages of unidirectional fibres?

• 70% lighter than steel, 40% lighter than aluminum
• High strength-to-weight ratio
• High corrosion resistance
• Application flexibility
• Increased the bending resistance of columns, beams and plates in almost any direction
• Ability to maintain column integrity through improved closure
• Spall protection in explosion-proof applications
• Ability to harden structural members without significantly increasing their size
• Installation speed
• Easy to integrate with other systems
• Economically increase capacity without weight or mass
• Very high tensile strength
• Lightweight and user-friendly installation
• Non-corrosive
• Low aesthetic impact
• Suitable for a variety of topcoats and protective coatings

Service

• Customization – Prepreg plies can readily be added or subtracted allowing the tube to be customized with different wall thicknesses
• Sample Acceptable – Because each tube is made one at a time, small production runs are available.
• CNC Machining — cutting according to your CAD drawing
• Print Logo – according to the AI file
• One- Stop Procurement – a whole industry chain of carbon fiber composite products

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.
