Roll Wrapped Carbon Fiber Tube with T700 Equivalent Carbon Fiber for High Strength-to-Weight Ratio and Thermal Stability

Roll Wrapped Carbon Fiber Tube Twill Weave Gloss Finish - Industrial Carbon Fiber Tube

Industrial carbon fiber tubes are high-strength, lightweight cylindrical structures made from carbon fiber reinforced polymer (CFRP). They are designed for demanding industrial applications where rigidity, corrosion resistance, and low weight are critical. These tubes are widely used across aerospace, robotics, automation, defense, and other heavy-duty industries.

This Roll Wrapped Carbon Fiber Tube uses high strength unidirectional T-700 equivalent carbon fiber core with an epoxy resin system to ensure a strong rigid tube that will meet your needs. In addition to this high strength uni core this tube is finished with a beautiful 2×2 twill weave carbon fiber and then given a gloss finish. Due to raw material constraints it is hard to create pipes exactly at a specific measurement unless they are built over-sized and machined down so that is why our pipes may be a few thousandths off from our ideal measurement we are trying to match.

Thanks to our industrial manufacturing processes (including Pultrusion, Pullwinding or K1 technologies) and extensive experience in composite materials, Epsilon designs and manufactures lightweight composite tubes and profiles in all shapes (round, oval, square, rectangle, or special shapes) using materials tailored to your needs:

Epoxy matrix (or other specific resins, as required),Carbon fiber adapted to mechanical stresses: High Strength (HS), Intermediate Modulus (IM), High Modulus (HM) or Very High Modulus (UHM),Natural fibers (flax, basalt,…),Synthetic fibers,Function integration (such as fiberglass or thermoplasic insulating/protective layer), Finishing (machining, assembly, non-destructive testing…).

What are Carbon Fiber Tubes?

Definition and Basic Characteristics

Carbon fiber tubes (also known as carbon fiber rods if they are stiffer and heavier) are predominantly cylindrical structures made from carbon fibers implanted in a polymer matrix, oftentimes an epoxy resin. They are however also available in other shapes such as rectangular or hexagonal, to suit different structural and design requirements. The CFRP tubes distinguish themselves in the market due to the high strength-to-weight ratio; they have more strength and are much lighter compared to their basic counterparts - like steel and aluminum. The carbon fibers provide high tensile strength, usually on the order of 3.5 GPa (Gigapascals), while the polymer matrix binds them together and provides some rigidity to the fibers for strengthening. Carbon fiber tubes also have a density of about 1.6 g/cm³ compared to steel at 7.8 g/cm³ and aluminum at 2.7 g/cm³.

Comparison with Other Materials

Carbon fiber tubes differ considerably compared to other materials. For instance, compared to steel and aluminum, carbon fiber tubes weigh approximately 70% and 40% less respectively, while having equivalent or better strength—application-related increased efficiency and performance, as seen in industries such as aerospace and automotive. In addition to this, carbon fiber tubes don't corrode like steel rusts over time or aluminum corrodes when the conditions dictate so. The modulus of elasticity for carbon fiber is about 230 GPa as compared to 200 GPa in steel and 69 GPa in aluminum, thus it shows that the CFRP tubes are stiffer and have less tendency to deform.

As for their thermal properties, Carbon fiber tubes again outperform traditional materials in terms of their thermal properties. Carbon fiber has a lower coefficient of thermal expansion (CTE) compared to steel and aluminum; that is, it expands and contracts less when subjected to variations in temperature. This dimension stability is highly demanded in applications where precision is a central requirement, as in aerospace and sporting equipment of high performance. Besides, carbon fiber's thermal conductivity is lower than metals, which makes it an excellent choice for applications requiring thermal insulation.

Besides that, any carbon fiber tube has greater fatigue resistance compared with its metal equivalents. Metallic materials, especially steel, and aluminum, upon experiencing cycles of load application and removal, tend to form micro-cracks, which will eventually lead to failure. Carbon fiber will maintain its integrity for a longer period under cyclic loading, a benefit particularly in aircraft structure applications and automotive parts where long-term durability is essential.

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,
