Pultruded Carbon Fiber Tube with 1K/3K/12K Weave for Dimensional Stability and Low Thermal Expansion

Pultruded Carbon Fiber Tube – Lightweight, High-Strength, Precision Engineered

Pultruded round carbon fiber tubes are created by pulling linearly-oriented carbon fibers through a resin bath and then a series of heated tooling to create the specified inner and outer diameters of the tube. Carbon tubes are especially stiff longitudinally, due to the unidirectional orientation of the fibers. These tubes are stiff, lightweight composites that can be used in a variety of applications, including robotics, aerospace, industrial equipment, and more.

We offer carbon fiber tubing in a variety of stock outer diameters from .125” to .750”. All lengths listed are +/- 0.062″, and all diameters listed are within +/- 0.005″. We can custom-cut your order to a specific length, and we’d be happy to speak with you about large, custom orders or machining.

LIJIN offers lightweight, durable carbon fiber tubes designed for superior strength and stiffness. Our carbon fiber tubes are manufactured using roll wrapping, pultrusion, or filament winding, ensuring consistent performance across structural, aerospace, and industrial applications.

Available in standard and custom sizes, our tubes outperform traditional materials in strength-to-weight ratio and are ideal for any project that demands precision and reliability.

Carbon fiber is the professional manufacturer and supplier of carbon fiber pultruded tubing. We offer the premium-quality pultruded carbon fiber tubes in various sizes and lengths. Pultruded carbon tubes are made from 100% real carbon fiber and vinyl ester or epoxy resins.

Pultruded Carbon Fiber Tube Features

• Lightweight: Significantly lighter than steel or aluminum, ideal for weight-sensitive applications.
• High Strength: Excellent tensile and flexural strength due to continuous fiber alignment.
• Corrosion Resistant: Resistant to chemicals, moisture, and environmental degradation.
• Dimensional Stability: Maintains shape and performance under temperature fluctuations.
• Low Thermal Expansion: Minimal expansion or contraction with heat changes.
• Precision Manufactured: Pultrusion process ensures consistent cross-section and quality.
• Electrical Insulation: Naturally non-conductive, suitable for electrical applications.
• Customizable Sizes: Available in various diameters, lengths, and wall thicknesses.

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.
