Carbon Fiber Tube Manufacturer Roll Wrapped and Filament Winding Process

Carbon Fiber Tube Manufacturer - Roll Wrapped and Filament Winding Process

LIJIN is proud to offer carbon fiber tubes, a revolutionary material known for its exceptional properties that significantly outperform traditional steel and aluminium. These tubes boast a remarkable strength-to-weight ratio, making them 6-12 times stronger than steel while being significantly lighter (less than 1/4th the density). This unique combination of strength and lightweight characteristics makes them ideal for demanding applications across a wide range of industries.

Where it's Been Used

LIJIN’s carbon fiber tubes excel in diverse applications due to their exceptional strength-to-weight ratio, corrosion resistance, and fatigue resistance.

• Robotics & UAVs: Lightweight drone arms, landing gear, etc.
• Industrial Automation: Telescopic manipulators for precise movement.
• Metrology: High-precision measuring equipment due to dimensional stability.
• Photography & Surveying: Stable and portable tripods.
• High-Performance Vehicles: Drive axles for weight reduction and strength.
• Cleaning: Long, durable cleaning poles.
• Industrial Machinery: Strong, stiff, and fatigue-resistant components.
• Sports Goods: Golf shafts, fishing rods, and more.
• Boats & Yachts: High-performance masts for superior strength and stiffness.

LIJIN’s carbon fiber tubes boast exceptional properties that outperform traditional materials:

• Unparalleled Strength-to-Weight Ratio: 6-12 times stronger than steel yet remarkably lightweight (less than 1/4th the density).
• Superior Tensile Strength: Withstands high pulling forces without compromising integrity.
• Corrosion & Shock Resistance: Resists rust, degradation, and impact for long-lasting performance.
• High Toughness & Modulus: Delivers exceptional rigidity and dimensional stability under load.
• Fatigue Resistance: Maintains strength and durability even under repeated stress.
• We manufacture high-quality carbon fiber tubes using Roll wrapped and Filament winding process

Roll Wrapped

Roll wrapped prepreg carbon fiber tubes are constructed using multiple wraps of twill and/or unidirectional fabrics.

• Ideal for small to medium diameter tubes (8mm – 100mm) and lengths up to 1.5 meters.
• Applications: Robotics, telescoping poles, rollers, UAV components.
• Fabric Options: 3K carbon fiber twill & plain weave.
• Finish Options: Glossy, Matte, or Sanded.
• Benefits: Highest bending stiffness and lowest weight for optimal performance in applications demanding rigidity and minimal weight.

Filament Winding

Filament winding is a composite manufacturing process in which continuous fibers or rovings are applied to a shape, known as a mandrel, to create a composite part.

• Suitable for a wider range of sizes, lengths, and finishes.
• Applications: Pressure vessels, drive shafts, and various industrial components.
• Benefits: Excellent for handling torsional stress due to the winding angle customization.

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.
