High Fatigue Resistance 1-4mm Thickness Twill Weave Carbon Fiber Sheets and Plates

High Fatigue Resistance 1-4mm Thickness Twill Weave Carbon Fiber Sheets and Plates

Carbon fiber sheets and plates are flat, rigid materials made from layers of carbon fiber-reinforced polymer (CFRP). They are known for their lightweight, high strength, and durability, making them ideal for a wide range of applications, including aerospace, automotive, sporting goods, and construction.

Application

• Aerospace: Used in manufacturing fuselage components, wing surfaces, and interior parts to enhance aircraft performance and fuel efficiency.
• Automotive Industry: Used in making body panels, chassis parts, and interior structures to reduce vehicle weight and improve fuel economy.
• Consumer Electronics: Utilized in producing laptop shells, smartphone back covers, and other components, offering lightweight and durable solutions.
• Medical Equipment: Applied in the production of lightweight medical devices, such as operating tables and wheelchairs, to improve ease of use.
• Sports Equipment: Used in the manufacture of bicycle frames, tennis rackets, and other sports gear, providing high-strength, lightweight equipment.
• Building Materials: Employed in constructing building components like curtain walls and staircases, enhancing the durability and aesthetics of structures.

Carbon Fiber Flat Plate Specification:

Production Process of Carbon Fiber Sheets and Plates

1. Raw Material Preparation: Prepreg Preparation: Use high-quality prepreg (carbon fiber fabric impregnated with epoxy resin) to ensure uniform resin content and carbon fiber alignment.

2. Cutting the Prepreg: Cutting: Cut the prepreg to the required size and shape according to the design specifications. Ensure clean edges during cutting to maintain accuracy in the subsequent lamination process.

3. Lamination: Laminating: Stack the cut prepreg layers according to the desired thickness and strength. Each layer of prepreg should be arranged in a specific direction to achieve optimal mechanical properties.

4. Placing in the Mold: Mold Preparation: Select an appropriate mold and place the stacked prepreg into the mold, ensuring the prepreg is flat and wrinkle-free. The mold surface should be treated with a release agent to facilitate demolding.

5. Vacuum Bagging: Bagging: Use a vacuum bag to seal the mold and prepreg, ensuring a good seal. The purpose of vacuum bagging is to remove air and prevent the formation of bubbles and voids during the autoclave process.

6. Autoclave Curing

• Curing: Place the sealed mold into the autoclave, setting the appropriate temperature, pressure, and time for curing. The typical curing temperature ranges from 120-180°C, with a pressure of 5-7 bar. The specific parameters are adjusted according to the properties of the prepreg and product requirements.
• Solidification: During the autoclave process, the resin in the prepreg will flow and cure, forming a solid and robust carbon fiber board structure.

7. Demolding

• Cooling: After curing, allow the mold and carbon fiber board to cool naturally to room temperature.
• Demolding: Carefully remove the carbon fiber board from the mold, ensuring no damage to the surface.

8. Post-Processing

• Trimming: Use cutting equipment to trim the edges of the carbon fiber board to achieve the final dimensions and shape.
• Surface Treatment: Perform surface treatments (such as sanding or coating) to achieve a smooth or matte finish as per customer requirements.

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.
