PA12-CF5 | 5% Carbon Fiber Reinforced Polyamide 12
PA12-CF5 is an advanced engineering thermoplastic that combines the flexibility and chemical resistance of Polyamide 12 (PA12) with the mechanical enhancement of 5% carbon fiber reinforcement. This composite delivers a unique balance of strength, stiffness, toughness, and environmental resistance, making it a reliable choice for high performance applications across industries such as automotive, aerospace, machinery, electronics, and consumer products.
The addition of carbon fiber introduces a fine reinforcement network within the polymer matrix, effectively improving the load bearing capacity and dimensional stability while keeping the material lightweight and easy to process. This makes PA12-CF5 an ideal substitute for metal or heavier plastics in semi structural or functional components.
Key Material Benefits
Mechanical Reinforcement
Carbon Fiber Content: 5%
Fine carbon fibers are uniformly distributed to enhance rigidity and dimensional control without significantly increasing brittleness or processing difficulty.
Tensile Strength: ≥ 70 MPa
Allows the material to endure high pulling forces, maintaining integrity under static or cyclic loads.
Flexural Strength: ≥ 100 MPa
Ensures resistance to bending and deformation—vital for housings, covers, and brackets that endure mechanical stress.
Impact Strength: ≥ 8 kJ/m²
Offers excellent resistance to sudden shocks or impacts, reducing the risk of crack propagation or failure in dynamic environments.
Thermal Stability
Heat Deflection Temperature (HDT): ~160°C
Retains shape and mechanical properties under elevated temperatures—ideal for automotive under hood or near engine uses.
Continuous Service Temperature: Up to 80°C
Suitable for long term exposure in moderate to high temperature environments, including machinery and electrical equipment.
Environmental and Chemical Resistance
Low Moisture Absorption
Unlike many polyamides, PA12 naturally absorbs little water. With added carbon fiber, PA12-CF5 offers exceptional dimensional stability, even in humid or wet conditions.
Chemical Compatibility
Exhibits excellent resistance to:
Automotive fluids (oil, grease, fuel)
Industrial solvents
Mild acids and alkalis
This makes it suitable for chemically aggressive settings such as engine bays, fuel system parts, and industrial enclosures.
Processing and Production
Processing Methods:
Compatible with injection molding and extrusion, allowing cost effective and scalable production of complex parts with high repeatability.
Flow Behavior:
Despite the fiber content, PA12-CF5 maintains good flowability, supporting thin wall designs and detailed part geometries.
Tooling Considerations:
Requires standard abrasion resistant tooling. Optimal results are achieved with uniform melt temperatures and controlled shear to minimize fiber breakage.
