Black Twill Matte Carbon Fiber Panels use for surfboard / boat centerboard

Twill Matte Carbon Fiber Plate 250mm * 350mm with material and standarstock.

Introduction

This carbon fiber plate unidirectional plate is layered up so that all carbon fibers run in 0° direction

(parallel to the long direction) of the part. It is used to add stiffness to almost any material: fiberglass,

foam, balsa wood, etc. The plate can be used for a variety of applications such as aircraft and rocket

fuselages, surfboards, boat centerboards, guitar necks, etc.

Information

Carbon filaments are often made from the oxidation and thermal pyrolysis of polyacrylonitrile material.

Polyacrylonitrile is a acrylonitrile-based polymer used in the creation of some synthetic materials.

Polyacrylonitrile molecules are made of long chains which are aligned by drawing continuous filaments.

When these chains are heated under the correct conditions they bond side to side forming ladder

polymers. Narrow graphene sheets are formed which merge together to make a single round filament.

This product is approximately 94-95% carbon. Instead of polyacrylonitrile, pitch or rayon can also be

used although this produces a lower-quality fiber. If the carbon is heat treated in the range of 1500-3000 degrees celcius, the fiber can become

a higher strength, higher molulus product.
The highest tensile strength (>800,000 psi) can be created by heating the fiber between 1500 and 2000

degrees. The highest modulus of elasticity (77,000,000 psi) can be obtained by heating the fiber material

from 2500 degrees to 3000 degrees. This balance between strength and elasticity is what allows a carbon

fiber hood to be so strong but also so durable. Carbon fiber density is about 1740 kg/m3. The three kinds

of carbon fiber are standard modulus, intermediate modulus and high modulus. Tensile strength tends to

vary between 2000 MPa and 7000 MPa. Rayon used to be a more popular precursor for carbon fibers

and is still used on some applications like rockets. However, it is not much more common for PAN or even

pitch to be used. The fiber yarns can be processed in many ways.

Advantage

1. High strength light weight

2. Low coefficient of thermal expansion

3. Resistance to corrosion

4. Durable nice surface ect.

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.
