Supply of Filament Wound Carbon Fiber Tube 3k woven wrapping carbon fiber texture .

Features

Carbon fiber composite material with the advantages of high strength, high modulus, low density, carbon

fiber has become one of the high performance of the most important.Carbon fiber composite material has

been widely used in aerospace, Marine, automotive, sports equipment and other fields, its important

features are:
1. Light weight, high strength
Its specific gravity 1.4 1.8 g/cm, is only a quarter of the steel, transportation and installation is very

convenient, compared with the plastic products, its strength is plastic products of dozens of times, so

remarkable characteristics is light weight, high strength carbon fiber composite materials.
2, corrosion resistance, anti-aging, long service life
Carbon fiber products to acid, alkali, salt, some organic solvents and other corrosive erosion, in the field

of corrosion protection has the incomparable superiority to other metals, and have good water resistance

and aging resistance, so no matter in corrosive environment and bad in the open air, wet environment

operation, its service life can reach more than 15 years.

Specification

Carbon fiber winding of molding process

Winding molding process is soaked in resin adhesive solution of continuous fiber (or cloth belt, presoak

yarn) on winding to the mandrel according to certain rules, and then after curing, demoulding, obtain

products.According to the filament winding forming physical and chemical condition when the resin is

different, divided into dry winding, wet winding and half dry winding 3 kinds.(1) dry winding Dry winding

is adopted through presoak rubber processing presoak yarn or, on a winding machine after soften to

viscous flow winding onto the mandrel.Because of presoak yarn (or with) is a professional production, to

strictly control the resin content (accurate to 2%) and presoak yarn quality.Therefore, dry winding can

accurately control the quality of the product.Dry winding process is the biggest characteristic of high

production efficiency, winding speed can reach 100 ~ 100 m/min, winding machine cleaning, labor health

condition is good, high product quality.The downside is winding equipment is expensive, need to increase

in yarn manufacturing equipment, so the investment is bigger also, dry low interlaminar shear strength

of winding products.

(2) the wet winding Wet winding is fiber cluster (yarn belt), glue, directly under tension control winding

onto the mandrel.The advantages of wet winding for: (1) 40% lower cost than dry winding;(2) the product

has good air tightness, because of the winding tension to squeeze bubbles, the excess resin adhesive

liquid and fill gaps;(3) fiber arrangement good parallelism;(4) the wet winding, fiber resin adhesive

solution, can reduce the fiber abrasion;5. High efficiency (up to 200 m/min).Wet winding faults as follows:

(1) resin waste is big, poor operating environment;(2) gel content and quality of the finished product is

not easy to control;(3) less available for wet winding resin varieties.

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.
