The three major advantages
Small thermal expansion coefficient, the vast majority of the thermal expansion coefficient of carbon fiber
itself, indoor negative (0.5 ~ 1.6) x 10-6 / K to zero during 200 ~ 400 ℃, in less than 10-1000 ℃ for
1.5 x 6 / K.Composite material made of it nature is stable, expansion coefficient can be used as a
standard measure.Outstanding damping with excellent through sonar using this two characteristics can
be used as structure materials, Carbon Fiber Tube such as submarine
sonar dome, etc.
Good abrasion resistance, carbon fiber and metal grinding, rarely
wear, made from carbon fiber to replace
asbestos advanced friction materials, has been as planes and cars
brake pad material.
Carbon fiber for high temperature performance is good, the
performance is very stable under 400 ℃,
even at 1000 ℃ is still no too big change.Composite material high temperature resistant performance
mainly depends on the heat resistance of matrix, and the resin matrix composite materials Feeding its
long-term heat resistant up to 300 ℃ or so, only ceramic base, carbon and metal based composite
material high temperature resistant performance can be matched with carbon fiber itself.So the carbon
fiber composite material as the high temperature resistant material
widely used in aerospace industry.
High X-ray transmission rate: the characteristic has been applied
in the medical equipment.
Carbon Fiber Tube Chemical properties:
Good: chemical corrosion resistance can be seen from the
composition of carbon fiber, it is almost pure carbon, and carbon
is one of the most stable elements.It besides the strong oxidizing
acid, acid, alkali and
organic chemicals are very stable, can be made into all kinds of chemical corrosion products.China has
engaged in the study of this aspect of the application, with the lower the price of the carbon fiber, its
Carbon Fiber Tube application scope will be more and more widely.

SHANGHAI LIJIN IMP.&EXP. CO.,LTD
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.
