In recent years, the problem of environmental pollution and energy shortage has become increasingly prominent. Energy conservation, environmental protection and light weight have gradually become one of the main trends in the development of new materials. Facing the lightweight trend of aerospace, rail transit, power electronics, new energy vehicles and other industries. High-strength light alloys, high-performance fibers, special alloys and other new materials are emerging, and carbon fiber is one of the most popular materials.
Carbon fiber has the highest specific strength, specific modulus and excellent thermal conductivity in all high-performance fibers. It is known as the 'king of materials'. Among them, carbon fiber is used as a reinforcement, combined with engineering plastics, corrosion resistance, low specific gravity, Carbon fiber reinforced thermoplastic composite (CFRTP) prepared by impact resistance, easy molding, secondary use, etc., has been widely used in automotive, electronics and other industrial fields due to its excellent performance. However, due to the difficulty of research and development, the domestic start is late. For other reasons, this material is mainly monopolized by large foreign companies.
As a new material technology company driven by technology, Jinyu New Materials has been committed to research and development of high-end advanced materials. In order to develop carbon fiber reinforced thermoplastic composite materials, Jinyu has set up an experienced technical team, after long-term research and development, continuous It has overcome several technical difficulties such as electromagnetic shielding and material heat conduction, and finally successfully developed carbon fiber reinforced thermoplastic composite materials.
At present, this material is applying for a number of technical patents. Its emergence will change the market competition pattern, break the current situation of high-end materials being monopolized by foreign countries, and promote the development of domestic lightweight technology.
It is understood that this material can maintain the carbon fiber length to the maximum extent, fully disperse into the engineering plastic matrix, improve the shortcomings of high-performance materials with poor surface quality, balance performance and aesthetics. Not only that, but it will reduce the price of similar materials. 50%, can provide more cost-effective material support for customers in the fields of new energy vehicles, electronics and other fields.
Professor Qiao Jinliang, chief expert of Sinopec Group Company, believes that with the localization of carbon fiber, the price of carbon fiber will be greatly reduced, the application will continue to expand, and the modified new materials formed after compounding with other engineering plastics will have a large market.
1, to reduce the cost of new energy vehicles, improve endurance
For new energy vehicles, the weight reduction means an increase in cruising range. Research shows that if the quality of a pure electric vehicle is reduced by 10kg, the driving range can be increased by 2.5km. The specific strength of carbon fiber reinforced thermoplastic composite is traditional metal material. 1.5~2.4 times, it can obtain higher load capacity with the same unit mass. It can replace 10%-20% weight loss with parts made of traditional metal materials and glass fiber reinforced materials.

The carbon fiber reinforced PA66 and PP series products developed by Jinyu have obvious weight reduction effects, high specific strength, high impact strength, easy molding and good surface quality. They solve the problem of unstable material quality and poor appearance quality of finished products. It can be applied to front-end modules, engine peripherals, body, seat frame, battery bracket, power battery pack and other components. Compared with traditional metal forming methods, the materials provided by Jinhao can be integrally molded by injection molding. Complex parts, while simplifying the process, reduce production costs and increase production efficiency. In addition, the use of lightweight materials can make the car's center of gravity move down, which helps to improve the safety and comfort of driving.
2, replacing traditional materials, boosting the upgrading of the electronics industry
Under the trend of consumption upgrading, consumers are increasingly demanding the appearance, quality, and technological sense of electronic and electrical products. Carbon fiber reinforced thermoplastic composite materials make the products lighter, more textured and more technological with superior performance. Fully meet the needs of consumption upgrades, has been widely used in computers, home appliances, communications, consumer electronics and other fields.
(1) Electronic and electrical housing: The housing is the most direct way to protect internal components, and it is also an important factor affecting the heat dissipation effect. With the development of thin and light electronic appliances, the traditional use of air-cooled or water-cooled cooling methods takes up a lot of space. Noise is generated and gradually eliminated by the market. The casing made of 66 旸 carbon fiber reinforced PA66 AC20L/AC40L has both solid metal and good weight reduction and thermal conductivity, enabling fanless design and carbon fiber Shielding performance, can also achieve electromagnetic shielding.

(2) UAV blades: UAV blades are the main output method of rotor drone power. Jinlu carbon fiber reinforced PPA HA40L can reduce the weight of the fuselage, improve endurance, reduce noise and reduce metal materials. For remote signal interference, simplify the molding process and enhance the flexibility of product structure design.

(3) Structural parts of electronic and electrical products: In order to ensure the strength, the traditional method is to use metal materials to make internal structural parts of electronic and electrical products, but this method is complicated in processing, long in molding, and increases the weight of the product. PA66 AC40L has excellent high strength, light weight and other characteristics, but also has the advantages of rapid production, easy mass production and easy recycling. Compared with traditional materials, it has better performance, lower cost and simpler process.
High voltage shielding equipment
China's lightweight technology started later than developed countries in Europe and America, and is still in the catching stage in terms of technology reserves and preparation processes. In recent years, China's new energy vehicles have risen rapidly, and home appliances, consumer electronics and other industries have started to upgrade consumption, which has rapidly driven the lightweight market. The development of domestic technology has been continuously improved, the preparation process has gradually matured, the production capacity has increased significantly, the products have become more competitive, and the scope of application has become wider and wider. It is foreseeable that with the continued development of technology and the further release of consumer demand, carbon fiber The lightweight materials represented by reinforced thermoplastic composites will usher in a broader space for growth. The new Chinese materials enterprises represented by Jinlu will gain market favor.
