The application of hydraulic press on carbon fiber, the king of new materials

Carbon fiber is known as the "king of new materials", with many performance advantages, such as light weight, high strength, high temperature resistance, corrosion resistance, so carbon fiber with its outstanding performance advantages, in aerospace, medical equipment, rail transit, automotive industry and other fields to obtain applications. So how are carbon fiber products produced, in this article we come to understand the carbon fiber products molding hydraulic molding process and application range.

Carbon fiber was originally used in military, aerospace and other high-tech fields, with the deepening of carbon fiber research and the reduction of carbon fiber cost, now the application of the civilian field is also gradually increasing, like some auto parts, sporting goods, it is worth mentioning that due to the outstanding X-ray transmission performance of carbon fiber materials, the application in medical devices is also gradually expanding. Automobile is one of the most widely used travel tools at present, the traditional automobile parts are made of metal materials, but there are shortcomings such as large weight, reduced performance, poor corrosion resistance, etc. In order to solve these problems, the manufacturing of most automobile parts will be made of carbon fiber composite materials processed by hydraulic presses of different tonnage according to different processes and production requirements. In this article, let's take a look at the advantages of carbon fiber auto parts hydraulic press. Carbon fiber materials have excellent plasticity, can process a variety of auto parts, but also can make integral components, auto parts in the manufacturing of carbon fiber composite materials, small density, is 60% of aluminum alloy, stainless steel 1/4, can effectively achieve the lightweight structure, to achieve the purpose of energy saving and emission reduction.

At the same time, the mechanical properties of carbon fiber materials are far better than traditional structural materials, its tensile strength can reach more than 3000MPa, which is several times that of steel, the comprehensive index of specific strength and specific modulus is better than existing structural materials, and it also has outstanding bending strength and shear strength, which can ensure the use of strength required. Carbon fiber is a non-metallic material with excellent corrosion resistance and can adapt to a variety of working environments.

Carbon fiber products molding molding process is simply to place carbon fiber prepreg between the upper and lower molds, the mold is placed on the molding platform of the oil press, after a certain period of high temperature and high pressure to cure the resin, carbon fiber parts can be obtained, the carbon fiber products made by this process, the surface is smooth, flat, and the strength retention rate is high.

In the hydraulic carbon fiber molding process, it is divided into three stages: flow stage, gelation and hardening, the first two stages determine the flow and flow time of the molded material, which is a prerequisite for ensuring the quality of the molded product, and the final stage is the key to grasp the amount of deformation of the product. In the production process need to pay attention to the temperature and pressure two factors. Molding is the control of temperature mainly refers to the molding temperature, heating rate, molding curing temperature and holding time. The role of pressure is to overcome the vapor pressure generated by volatile substances in the material, avoid the defects such as bubbles, stratification, and loose structure of the product, and also increase the fluidity of the material. For products with thicker walls, the molding pressure should be appropriately increased.

Carbon fiber molding hydraulic press features:

1, four-column hydraulic press with rapid prototyping, energy saving, environmental protection and other main characteristics.

2, the use of four-column guide structure, high guiding accuracy, strong resistance to lateral force, suitable for pressing precision requirements, asymmetric products.

3, the use of forged steel finishing, thickening treatment, with good rigidity, strong deformation resistance.

4, moving table from top to bottom movement, improve product processing accuracy and operation safety.

5, with fast work, slow mold function, improve production efficiency and mold life.

6, four columns and three beams structure, simple, economic, practical. 45# integral cast steel, good rigidity, strong and durable; High precision;

7, hydraulic control using cartridge valve integrated system, reliable action, small hydraulic impact, long service life, less leakage point, reduce the connection pipeline and leakage point.

8, the new cylinder sealing element, high reliability, long service life, up to 600,000 times.

9, independent electrical control system, reliable work, intuitive action, easy maintenance. Button centralized control, with adjustment, manual and semi-automatic control.

10, stretching, pressing slider can be connected into one, to achieve single action process action.

11. Mechatronics safety device. Such as: cylinder lower cavity support loop, cylinder upper and lower cavity interlock loop, etc., superior safety.

12, it can be adjusted according to the process requirements within the specified range: fixed pressure, fixed process two kinds of molding process, easy to operate.
