Roll Wrapped Oval Carbon Fiber Tube , Lightweight & Aerodynamic Composite Tubing

Roll Wrapped Oval Carbon Fiber Tube, Lightweight & Aerodynamic Composite Tubing

Oval carbon fiber tubes offer a unique combination of aerodynamics, structural strength, and lightweight performance. Designed for applications where airflow efficiency and directional rigidity are critical, these tubes are widely used in industries like aerospace, cycling, sports equipment, drones, and high-performance automotive systems.

Crafted using high-quality carbon fiber and advanced manufacturing techniques such as roll wrapping or pultrusion, oval tubes provide the same impressive strength-to-weight ratio as round and square carbon fiber tubes, while optimizing airflow and structural integration.

Why Choose Oval Carbon Fiber Tubes?

The oval shape combines the best of both worlds: it reduces wind resistance compared to round tubes and offers better lateral rigidity than flat profiles. This makes it an ideal structural component when minimizing drag and maximizing directional strength is a priority.

Key Features

• Aerodynamic Profile: Streamlined oval shape reduces drag in high-speed applications
• High Strength-to-Weight Ratio: Made from premium carbon fiber for superior stiffness
• Directional Rigidity: Enhanced resistance to bending in a specific axis
• Customizable: Available in various sizes, thicknesses, finishes, and weave types
• Corrosion & UV Resistant: Suitable for harsh outdoor and high-performance environments
• Smooth Surface Finish: Offered in glossy or matte, with 3K twill or plain weave outer layer

Common Applications

• Bicycle Frames & Seat Posts – Lightweight and aerodynamic for competitive cycling
• UAV/Drones – Reduced air drag and enhanced flight efficiency
• Automotive Spoilers & Body Panels – High stiffness with sleek styling
• Sports Equipment – Hockey sticks, paddles, and performance gear
• Aerospace Components – Structural parts requiring airflow efficiency

Technical Options Available

• Weave Patterns: 3K Twill, Plain Weave, Unidirectional
• Manufacturing Process: Roll-Wrapped or Pultruded
• Surface Finish: Glossy, Matte, or Satin
• Customization: Length, outer dimensions (major/minor axes), wall thickness

Oval carbon fiber tubes are engineered for speed, strength, and precision. Whether you're designing a drone for efficient flight, a high-performance bicycle, or a lightweight automotive component, oval tubing gives you the advantage of aerodynamics without compromising on strength.

With custom sizes, finishes, and fiber layouts available, you can optimize your design with performance-grade composite tubing tailored to your specific application.

CNC machining is precision and cost-effective way to achieve innovation and creativity, which triggers out our endless imagination and creative inspiration. We had made so many different carbon CNC parts for racing parts, RC helicopters, bicycle bracket, and reinforcements for mor than 10 years.

Usually, these structural components include a wide range of processes such as printing logo, cutting edges, cutout, drilling holes on the solid sheet or tubes. All the machining parts are controlled by our CNC technicians, and both tolerance and surface quality are strictly inspected by the quality inspection department before shipping the goods. Integrated CNC machining enables us to help our customers produce parts efficiently.

4. Drilling and slotting are accepted.
5. We guarantee the products to be manufactured with the finest materials and mature techniques.
All tubes can be repaired at no charge if returned to us, postage prepaid, within one year.

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.
