Carbon Fibre Straight Pipes Layered With Epoxy Resin And Varnished Outer Finish

Carbon Fibre Straight Pipes - Layered with quality epoxy resin and varnished outer finish

Carbon Fibre Pipes are advanced composite materials known for their exceptional strength-to-weight ratio, making them highly sought after in various industries. These tubes are manufactured using carbon fiber Piping reinforcement, which is composed of extremely thin strands of carbon atoms aligned in a crystal lattice pattern. This alignment provides the material with its remarkable strength and stiffness. Carbon fiber has a distinctive woven texture and high-tech appearance.

How are Carbon Fibre Pipes made?

Carbon fibre pipes are typically manufactured using a process called filament winding. Here are the detailed steps involved:

Preparing the mandrel: A mandrel, which is a cylindrical tool, is prepared with the required dimensions and shape for the carbon fibre pipe. It is made of materials such as aluminum, steel, or plastic and is usually coated with a release agent to prevent the pipe from sticking to it.

Preparing the carbon fiber: The carbon fibre is typically in the form of a woven fabric or unidirectional tow. The fibers are impregnated with a resin, usually epoxy, which is mixed with a hardener to form a tough, durable composite material.

Filament winding: The impregnated carbon fibre is wound around the mandrel in a specific pattern using a filament winding machine. The machine rotates the mandrel while a filament winding head guides the carbon fibre onto the mandrel. The winding pattern is chosen based on the required properties of the finished pipe, such as strength, stiffness, and durability.

Curing: Once the desired number of layers of carbon fibre has been wound onto the mandrel, the pipe is heated to cure the resin. The curing process is typically done in an oven or autoclave, depending on the specific resin used. The heat and pressure applied during the curing process help to bond the fibres and resin together, creating a strong, durable composite material.

Finishing: Once the curing process is complete, the carbon fibre pipe is removed from the mandrel. It may then undergo additional finishing processes such as sanding or polishing to achieve the desired surface finish. The ends of the pipe may also be trimmed or machined to the required dimensions.

Quality control: The finished carbon fibre pipe is inspected for defects and undergoes testing to ensure it meets the required specifications for strength, stiffness, and durability.

Overall, carbon fibre pipes are made using a precise and controlled manufacturing process to ensure high-quality, consistent performance.

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.
