High Quality Roll Wrapped 3K Twill Weave Carbon Fiber Tube Pipe

Carbon fiber has the best combination of high strength, high stiffness, and lightweight. Our carbon fiber tube is as strong as steel, as stiff as aluminum, and lighter than titanium. Carbon fiber tubes can replace metal tubes in many applications. We offer a wide range of tubes to fit your needs.

Carbon Fiber Tube Features:

• High strength and stiffness to weight
• Excellent resistance to fatigue
• Dimensional stability: Low CTE (Coefficient of Thermal Expansion)
• Resistance to corrosion
• X-Ray transparency
• Chemical resistivity

Carbon Fiber Tube Specifications:

We have been engaged in the production of fiber materials for more than 10 years and have a strong engineering team. We will formulate complete solutions for customers from multiple perspectives such as product transportation, installation, maintenance, and cost-effectiveness according to the use conditions and performance requirements of the products.

Carbon Fiber Tube Manufacturing Process:

4-Axis braiding is a process in which we braid carbon fibers over a mandrel. The braiding machine stays in one place and an aluminum mandrel traverses inside of the braiding hoop. The layer of braid is then wet-out with epoxy resin at a 2nd stage in the machine. The laminate is then consolidated and cured at 280F.

• Braided composite structures offer extreme durability and toughness due to the interlocking fibers and no seams.
• If damage does occur, it does not tend to propagate within the structure.
• Typically braided carbon tubes have approximately 75% of fibers directly on the axis of the tube. These fibers are continuous fibers from one end of the part to the other. 10 % of the fibers are +/- 45 deg and around 15% are 90 deg (hoop)
• We can make some adjustments to the percentages of fiber orientation; however, it is not possible to get high percentages of +/- 45 deg.
• The inherent high percentage of fiber on the 0 axis makes a braided tube a very good compression or bending tube.
• Because the machine stays in one place and the mandrel traverses, there is no length limitation to the parts that can be built (the building length, oven length, and mandrel lengths are limiting factors, but the process itself is not limited).
• We typically braid longer-length parts or larger manufacturing runs compared to pre-preg.
• Braided carbon fiber tubes tend to have more surface ripples and small voids in the laminate. This is not a structural issue but it can be a cosmetic issue and it may have an effect on the OD tolerance of the part.

Examples of some applications for braided tubing

Communications towers, large antenna assemblies, portable antennas, drone wing spars, aircraft structural tubing, sailboat spars, truss tubing, reinforcing tubes, spacer tubes, stiffening tubes, compression struts, GPS towers, high tension cable struts, awning support tubes, structural beams, low interference towers.

FAQ

Q: Are you a manufacturer?
A: Yes, we are a manufacturer, welcome to visit our factory!

Q: Can I have a sample order?
A: Yes, we welcome sample orders to test and check quality. Mixed samples are acceptable too.

Q: What is the lead time?
A: Standard size Sample needs 5 days, mass production needs 15-30 days, according to the quantity

Q: Do you offer OEM service?
A: We accept OEM orders for all our production lines, including the client's logos and labels. After many years of exploration and development, we are sure we can meet all your requirements.

Q: How long can I get a response after I send an inquiry?
A: We will reply to each inquiry within 12 hours.

Q: Your quotation does NOT meet my target price
A: We can propose materials, accessories, or design alternatives to lower the price of your project

Q: What is carbon fiber used for?
A: Carbon fiber -- sometimes known as graphite fiber -- is a strong, stiff, lightweight material that has the potential to replace steel and is popularly used in specialized, high-performance products like aircraft, race cars and sporting equipment.

Q: Is carbon fiber stronger than steel
A: Carbon fibers are classified by the tensile modulus of the fiber. ... Thus, the strongest carbon fibers are ten times stronger than steel and eight times that of aluminum, not to mention much lighter than both materials, 5 and 1.5 times respectively.

Q: Why is carbon fiber so expensive?
A: Another carbon fiber cost factor is energy. ... It takes a lot of energy to reinforce each fiber with carbon atoms. Energy, is also required to bundle the carbon together into fibers and threads. Energy costs are probably the most expensive factor in carbon fiber manufacturing.

Q: What are the advantages and disadvantages of carbon fiber?
A: Carbon fiber reinforced polymer (CFRP) materials possess good rigidity, high strength, low density, corrosion resistance, vibration resistance, high ultimate strain, high fatigue resistance & low thermal conductivity. They are bad conductors of electricity and are not magnetic.

Q: Is carbon fiber resistant to water?
A: The carbon fiber in the composite does not absorb water from the environment, and its resistance remained unchanged when immersed in water.

Q: Is carbon fiber the future?
A: The future of carbon fiber is undoubtedly on a positive course. However, the speed at which carbon fiber integrates into larger commercial markets and more and more common applications is largely dependent on the capabilities of existing carbon fiber manufacturers.

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.
