Engineered for high-performance applications, PA6-CF60 excels in environments where superior mechanical characteristics and minimal weight are critical. This composite material is particularly valuable across various industries, including automotive, aerospace, consumer goods, and industrial sectors.

Key Properties of PA6-CF60

Base Material: Polyamide 6 (PA6)
Polyamide 6 serves as the foundational polymer for PA6 CF60. Known for its excellent mechanical properties, PA6 offers a balance of strength, flexibility, and toughness. When enhanced with carbon fibers, PA6 transforms into a high-performance material capable of withstanding demanding conditions.

Reinforcement: Carbon Fibers (CF)
With a reinforcement of 60% carbon fibers, PA6 CF60 exhibits substantial improvements in mechanical strength and stiffness compared to both unreinforced PA6 and PA6 variants with lower fiber content. The high tensile strength and resilience of carbon fibers enhance the overall performance of the composite, making it suitable for structural applications in high-load scenarios.

Density: Approximately 1.8 g/cm³
PA6-CF60 has a density of approximately 1.8 g/cm³, which is relatively low for a reinforced composite. This lightweight characteristic is crucial in industries such as automotive and aerospace, where reducing weight can lead to improved fuel efficiency and performance.

Tensile Strength: 250-280 MPa
The tensile strength of PA6 CF60 ranges from 250 to 280 MPa, significantly higher than unreinforced PA6. This strength ensures that components can endure substantial forces without failure, making it ideal for critical structural applications.

Flexural Modulus: 11000-12000 MPa
With a flexural modulus between 11000 and 12000 MPa, PA6 CF60 exhibits high stiffness, resisting deformation under bending stresses. This property is vital for applications that require components to maintain their shape and integrity under load, ensuring long-term durability.

Impact Resistance: Outstanding (up to 400% improvement)
One of the standout features of PA6 CF60 is its exceptional impact resistance, showing up to a 400% increase compared to unreinforced PA6. This durability makes it suitable for safety-critical components, such as automotive crash structures and industrial equipment exposed to high-impact forces.

Thermal Stability: Stable up to 300°C
PA6 CF60 demonstrates remarkable thermal stability, maintaining its mechanical properties at temperatures up to 300°C. This is essential for components operating in high-heat environments, such as engine parts and electronic enclosures, where reliable performance is crucial.

Melt Flow Index: Low (typically < 5 g/10 min)
The low melt flow index of PA6 CF60 indicates a high viscosity during processing, which is beneficial for achieving precise shapes and dimensions in molded parts. This property ensures consistency and quality in manufacturing processes like injection molding and extrusion.

Water Absorption: Very Low (up to 0.2%)
With a moisture uptake of only about 0.2%, PA6 CF60 exhibits excellent dimensional stability and resistance to environmental degradation. This low water absorption is particularly advantageous for outdoor applications, where moisture exposure can negatively affect performance.

Color: Black 
PA6 CF60 is typically available in black, though it can also be customized to meet specific aesthetic requirements. This flexibility allows manufacturers to align the material with branding and design needs while retaining its performance characteristics.

Processing Method: Injection Molding, Extrusion
PA6 CF60 can be processed using common methods such as injection molding and extrusion. This versatility facilitates the production of complex components and parts, making it suitable for a wide range of applications across various industries.
