Roll Wrapped Carbon Fiber Kevlar Tube Extremely Strong Stiff And Lightweight

Roll Wrapped Carbon Fiber Kevlar Tube - Extremely Strong, Stiff and Lightweight

What is a Carbon Kevlar Tube?

A Carbon Kevlar Tube is a hollow, cylindrical structure made from a composite of carbon fiber and Kevlar fibers. These tubes are typically manufactured by layering the two materials in a specific pattern to leverage the benefits of both.

A Carbon Kevlar Tube combines the properties of carbon fiber and Kevlar to create a composite material that offers a unique combination of strength, stiffness, and durability, while also being relatively lightweight.

Carbon Fiber: Provides excellent tensile strength, stiffness, and lightweight.
Kevlar: Adds superior impact resistance and toughness, especially against abrasion, tearing, and deformation.

Our roll-wrapped carbon fiber tubes are manufactured by wrapping multiple layers of 12k UD and 3k twill/plain carbon fiber prepregs around a metal mold and then cured at high temperatures. The UD prepregs are used in core layers whereas the Twill/Plain is on the surface. Based on your requirements, we can also use Kevlar and glass fiber.

Available in matte and gloss finishings, these tubes are not only good-looking but also extremely stiff and strong. Such roll-wrapped tubes are available in round, square, rectangular, hexagon, and octagon shapes. All these tubes are custom-made based on the client’s requirements.

Common Applications of Carbon Fiber Tube

• Aerospace beams and spars
• Telescopes
• Arrows
• Robotics
• Arrow Shafts
• Bicycle frames
• Kayak paddles
• RC models
• Yachts

Carbon fiber tubes are extremely strong and stiff but lightweight. Hence, if you are looking for the strength of a steel/aluminum tube but at 1/3rd weight, our carbon fiber tubes are an ideal replacement.

Benefits of Carbon Kevlar Tubes:

• High Strength-to-Weight Ratio: The combination of carbon fiber and Kevlar provides an excellent balance between strength and weight.
• Impact Resistance: Kevlar is known for its high toughness and ability to absorb impacts, which makes the tube more resistant to damage from sudden forces.
• Durability: The Kevlar layers increase resistance to wear, tear, and abrasion, extending the life of the tube in demanding environments.
• Corrosion Resistance: Like pure carbon fiber, Carbon Kevlar tubes resist rust and corrosion, making them suitable for harsh environments.
• Flexibility and Stiffness: The composite structure offers a good balance of rigidity with enough flexibility to withstand impacts without breaking.

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.
