I. Introduction to PEEK LCF10 Composite Material

(I) Composition

PEEK LCF10 is a thermoplastic composite material with polyether-ether-ketone as the base material and 20% long carbon fiber as the filling material for reinforcement. This unique combination endows the material with both the high performance of PEEK and the reinforcing characteristics of carbon fiber.

(II) Performance Characteristics

1. High strength and high rigidity: The addition of long carbon fiber greatly enhances the strength and rigidity of the material. Carbon fiber has extremely high tensile strength and elastic modulus, which can effectively distribute stress, making the PEEK LCF10 composite material less prone to deformation and fracture when subjected to large loads. For example, under the same size and load conditions, components made of PEEK LCF10 composite material are several times stronger than traditional plastic components.
2. Good heat resistance: PEEK itself has excellent heat resistance and can maintain stable performance in high-temperature environments. The presence of carbon fiber further enhances the dimensional stability and mechanical properties of the material at high temperatures. This material can be used for a long time at temperatures up to 250°C, and can even withstand higher temperatures for a short time, which gives it a great advantage in high-temperature working environments.
3. Low friction coefficient: The PEEK LCF10 composite material has a low friction coefficient, which reduces wear and energy loss when used in moving parts. For example, using this material in bearings, gears and other parts can extend the service life of the parts and improve the operating efficiency of the equipment.
4. Good corrosion resistance: It can resist the erosion of various chemical substances, including acids, alkalis, organic solvents, etc. This makes it have great potential in harsh environments such as chemical industry and petroleum. Whether in corrosive media or in humid environments, the PEEK-LCF10 composite material can maintain good performance.
5. Excellent electrical insulation performance: This material has good electrical insulation performance and can effectively prevent current leakage and electrostatic accumulation. This makes it widely used in the field of electronics and electrical appliances, such as manufacturing high-performance insulating parts, circuit boards, etc.
6. Outstanding flame retardant performance: The PEEK LCF10% composite material is self-extinguishing and not easy to burn. Even in case of fire, it can be extinguished quickly without producing toxic gases. This characteristic makes it have important application value in fields with high safety requirements, such as aerospace and rail transit.

II. Application Case

In the field of aerospace, a new type of unmanned aerial vehicle (UAV) wing component adopts PEEK LCF10 composite material. This UAV has extremely high requirements for the strength, rigidity and light weight of the wing.

The high strength and high rigidity of the PEEK 10%LCF composite material ensure the stability of the wing under high-speed flight and complex airflow conditions. Compared with traditional materials, its weight is reduced by 30%, which greatly improves the endurance of the UAV. At the same time, the good heat resistance of the material enables it to adapt to the low temperature at high altitude and the high temperature near the engine. The excellent electrical insulation performance also provides reliable protection for the electronic equipment of the UAV.

During the production process, Carbon (Xiamen) New Material Company provides high-quality PEEK LCF10 composite material. Their professional technical team works closely with UAV manufacturers to customize and optimize materials according to the specific requirements of UAVs. After strict testing and verification, the composite wing components have shown excellent performance.

In terms of specific data, the wing made of PEEK+LCF10 composite material can withstand a lift force of up to 500 Newtons, and its own weight is only 70% of that of traditional metal wings. In the corrosion resistance test, after being soaked in a simulated harsh environment for 1000 hours, no obvious corrosion phenomenon appears. In addition, the low friction coefficient reduces the air resistance of the wing during flight by 15%, further improving the flight efficiency of the UAV. And the outstanding flame retardant performance also provides a strong guarantee for the flight safety of the UAV.
