100% Unidirectional Carbon Fiber Pultruded Tube – 7mm X 5mm X 1000mm

100% Unidirectional Carbon Fibre Pultruded Tube – 7mm x 5mm x 1000mm

Carbon fiber pultruded tubes offer an excellent balance of strength, weight, and durability, making them suitable for a wide range of applications across different industries. Pultruded carbon fibre round tube manufactured from 100% unidirectional carbon fibre.

The tube has an outer diameter (OD) of 7mm and an inner diameter (ID) of 5mm.

Enhanced Composites carbon fibre tube uses high-strength 12K carbon fibre yarn with an epoxy resin system to ensure a strong rigid rod that will meet the highest standards.

Pultruded products perform incredibly well in bending and tension (pulling) applications since all the fibres are oriented along the length of the tube (or rod). They do not however perform well in other loading scenarios such as torque, torsional move, side loads, or crushing.

How to Cut and Shape

They can be cut with a band saw, coping saw, scroll saw, end mill, or Dremel tool. Because Enhanced Composites pultruded carbon fibre tubes are manufactured using an epoxy matrix they will easily bond with epoxy resins.

Typical Uses

These light 7mm tubes are ideal for scale aircraft, gliders, helicopter UAVs or any construction that requires strength, rigidity and lightness but would be equally suited to other precision applications like robotics and automation. We do not recommend the pultruded tubing or rod in applications such as drone or UAV motor (boom) arms.

Pultrusion is a manufacturing process used to produce continuous lengths of composite materials with a constant cross-section. When it comes to carbon fiber, pultrusion can be used to create carbon fiber pultruded tubes. Here are some key aspects of carbon fiber pultruded tubes:

Pultrusion Process:

1. Resin Impregnation: Pultrusion involves pulling fibers (such as carbon fibers) through a resin bath where they are thoroughly impregnated with a liquid resin. The resin can be epoxy, polyester, or another suitable matrix material.
2. Molding and Curing: The impregnated fibers are then pulled through a shaping die to form the desired cross-sectional shape, in this case, a tube. The entire assembly is then passed through a heated die to cure and harden the resin.
3. Continuous Production: One of the advantages of pultrusion is that it allows for the continuous production of composite materials with consistent properties along the length.

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.
