Continuous Carbon Fiber Reinforced Thermoplastic Polyether Ether Ketone CF-PEEK Laminate T300-Fabric

Continuous carbon fiber reinforced thermoplastic polyetheretherketone (CF-PEEK) laminate is a high-performance engineering material manufactured using advanced composite processes. It employs thermoplastic polyetheretherketone (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 integrated, resulting in a laminate material with outstanding comprehensive properties.

II. Core Advantages

(I) Excellent Mechanical Properties

The incorporation of continuous carbon fiber endows the laminate with extremely high strength and stiffness, 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 CF-PEEK laminate to maintain long-term stability within a broad temperature range of -100°C to 260°C. In high-temperature environments, the material does not exhibit significant softening, deformation, or performance degradation, making it suitable for demanding applications such as aerospace, automotive engine peripherals, and electronic and electrical equipment. For example, in high-temperature components of aircraft engines, this 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 offers excellent resistance to chemical corrosion, capable of withstanding most acids, alkalis, salts, and organic solvents. CF-PEEK laminate inherits this characteristic, maintaining material integrity and performance stability in harsh chemical environments found in industries such as chemical, petroleum, and pharmaceuticals. This prevents structural damage and functional failure due to chemical corrosion. Furthermore, the material has low moisture absorption, reducing dimensional changes and performance fluctuations caused by moisture in humid environments.

(IV) Lightweight and High Strength, Low Density

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

(V) Good Processability

The thermoplastic PEEK matrix gives CF-PEEK laminate the characteristic of being reprocessable. It can be processed using various thermoplastic molding techniques such as compression molding, and it is also suitable for secondary mechanical processing like drilling, milling, and cutting. With high processing precision, it meets the manufacturing requirements of various complex structural components. Additionally, the material exhibits good weldability and can be joined through methods such as thermal welding and laser welding, facilitating component assembly and maintenance.

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, enhance flight performance, and meet the usage requirements in high-temperature and high-pressure environments of aircraft engines. Additionally, it can be used for structural parts 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. It can withstand the high-temperature and high-pressure conditions of engines, reducing the risk of thermal deformation and component failure. Moreover, using CF-PEEK laminate in automotive chassis and body structures can reduce weight, improve fuel economy, and enhance vehicle handling and safety. It is also suitable 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 offers excellent electrical insulation and high-temperature resistance. It can be used to manufacture 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. Its lightweight and high-strength properties also make it suitable for structural components of portable electronic devices, such as laptop casings and smartphone frames, enhancing strength and durability while reducing device weight.

(IV) Medical Device Field

Due to the excellent 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 those of human bones, providing effective support and fixation while reducing complications associated with metal implants. Additionally, it can be used for surgical instruments and structural components of medical equipment, meeting the requirements of high strength, corrosion resistance, and biocompatibility in medical devices.

(V) Other Fields

Beyond the aforementioned 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 produce high-end products such as golf clubs and tennis rackets, improving performance and quality. In the energy sector, 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.
