Continuous Carbon Fiber Reinforced Thermoplastic Polyether Ether Ketone CF-PEEK Laminate

Continuous Carbon Fiber Reinforced Thermoplastic Polyether Ether Ketone CF-PEEK Laminate is a high-performance engineering material manufactured using advanced composite processes. It utilizes thermoplastic polyether ether ketone (PEEK) as the matrix and continuous carbon fiber as the reinforcement. Through scientifically rational interlayer structural design and composite molding technology, the advantages of both materials are perfectly combined, resulting in a laminate material with outstanding comprehensive properties.

II. Core Advantages

(I) Excellent Mechanical Properties

The addition of continuous carbon fiber imparts extremely high strength and stiffness to the laminate, far surpassing traditional metal materials and ordinary engineering plastics. It can operate stably under high-load, high-stress complex working conditions, providing reliable mechanical support for structural components. Additionally, the material exhibits good fatigue resistance, with a long fatigue life under long-term alternating loads, reducing equipment maintenance and replacement costs.

(II) Outstanding High-Temperature Resistance

The PEEK matrix itself possesses excellent high-temperature resistance, with a glass transition temperature of approximately 143°C and a melting point as high as 343°C. This enables the CF-PEEK laminate to be used stably over a wide temperature range from -100°C to 260°C. In high-temperature environments, the material does not exhibit significant softening, deformation, or performance degradation, making it suitable for applications with stringent high-temperature requirements, such as aerospace, automotive engine peripherals, and electronic and electrical equipment. For example, in high-temperature components of aircraft engines, the laminate can withstand the impact of high-temperature gases and long-term high-temperature exposure, ensuring the normal operation of the components.

(III) Good Chemical Stability

PEEK has excellent chemical corrosion resistance, capable of resisting most acids, alkalis, salts, and organic solvents. The CF-PEEK laminate inherits this characteristic, maintaining material integrity and performance stability in harsh chemical environments such as the chemical, petroleum, and pharmaceutical industries, preventing structural damage and functional failure due to chemical corrosion. Furthermore, the material has low moisture absorption, reducing water uptake in humid environments and minimizing dimensional changes and performance fluctuations caused by moisture absorption.

(IV) Lightweight and High Strength, Low Density

The density of carbon fiber is only about 1.7 g/cm³, and the density of the PEEK matrix is approximately 1.3 g/cm³, resulting in an overall low density for the CF-PEEK laminate, typically between 1.4–1.6 g/cm³. Compared to traditional metal materials such as aluminum alloy (density about 2.7 g/cm³) and steel (density about 7.8 g/cm³), it offers a significant lightweight advantage. In fields like aerospace and automotive manufacturing, using this laminate can significantly reduce structural weight, thereby lowering energy consumption, improving efficiency, and increasing payload capacity.

(V) Good Processability

The thermoplastic PEEK matrix gives the CF-PEEK laminate the characteristic of being reprocessable. It can be processed using various thermoplastic molding techniques such as compression molding and can also undergo secondary mechanical processing, including drilling, milling, and cutting, with high precision to meet the manufacturing requirements of various complex structural components. Additionally, the material has good weldability and can be joined through methods such as thermal welding and laser welding, facilitating component assembly and repair.

III. Application Fields

(I) Aerospace Field

In the aerospace industry, CF-PEEK laminate can be used to manufacture aircraft structural components, such as wing skins, fuselage frames, and tail components. Its lightweight, high strength, high-temperature resistance, and fatigue resistance effectively reduce aircraft weight, improve flight performance, and meet the usage requirements in high-temperature and high-pressure environments of aircraft engines. Additionally, it can be used for structural components of satellites, ensuring reliability and stability in extreme space environments.

(II) Automotive Manufacturing Field

In the automotive industry, this laminate can be applied to engine components such as valve covers, intake manifolds, and turbocharger housings, capable of withstanding high-temperature and high-pressure environments of engines, reducing thermal deformation and failure risks of components. At the same time, using CF-PEEK laminate in automotive chassis and body structures can reduce weight, improve fuel economy, and enhance vehicle handling and safety. Furthermore, it can be used for heat dissipation components and structural supports in automotive electronic devices.

(III) Electronic and Electrical Field

In the electronic and electrical industry, CF-PEEK laminate has good electrical insulation properties and high-temperature resistance, making it suitable for manufacturing high-frequency circuit boards, electronic component encapsulation shells, and heat dissipation substrates. In environments with high temperatures, high humidity, or chemical corrosion, it ensures the stable operation of electronic equipment. Additionally, its lightweight and high-strength characteristics make it suitable for structural components of portable electronic devices, such as laptop casings and phone frames, reducing device weight while enhancing strength and durability.

(IV) Medical Device Field

Due to the good biocompatibility of PEEK material, CF-PEEK laminate has broad application prospects in the medical device field. It can be used to manufacture orthopedic implants, such as bone plates, bone screws, and joint prostheses. Its mechanical properties are similar to human bones, providing good support and fixation effects while reducing complications caused by metal implants. Furthermore, it can be used for surgical instruments and structural components of medical equipment, meeting the requirements of medical devices for high strength, corrosion resistance, and biocompatibility.

(V) Other Fields

Beyond the above fields, CF-PEEK laminate can also be applied in industrial machinery, sports equipment, energy, and other industries. In industrial machinery, it can be used to manufacture high-precision gears, bearings, and transmission components. In sports equipment, it can be used to manufacture high-end products such as golf clubs and tennis rackets, improving product performance and quality. In the energy field, it can be used to manufacture components like fuel cell bipolar plates and solar panel brackets, meeting the demand for high-performance materials in the new energy industry.
