Introduction to PA12-LCF30 Material
PA12-LCF30 (Polyamide 12 Carbon Fiber Composite with 30% Carbon Fiber) is an advanced thermoplastic composite material that incorporates 30% carbon fiber reinforcement within a polyamide 12 (PA12) matrix. This composition offers superior strength, rigidity, and thermal stability compared to lower carbon fiber contents. With enhanced mechanical and thermal properties, as well as excellent chemical resistance, PA12-LCF30 is ideal for demanding applications in sectors such as automotive, industrial, and consumer goods, where high performance and durability are essential.
Characteristics and Values for Enhanced Performance
Carbon Fiber Content: 30%
The 30% carbon fiber content in PA12-LCF30 provides a substantial boost in tensile and flexural strength, giving the material the ability to withstand higher stress and loads while maintaining its lightweight advantage. This makes it suitable for applications requiring even greater strength and stiffness than the 20% variant, without significantly increasing weight.
Tensile Strength: ≥ 120 MPa
With a higher carbon fiber content, PA12-LCF30 demonstrates improved tensile strength, allowing it to support greater loads without permanent deformation. This characteristic is especially valuable for parts subjected to higher stress in demanding applications.
Flexural Strength: ≥ 210 MPa
The flexural strength of PA12-LCF30 means it is highly resistant to bending and shape deformation, which is essential for components exposed to heavy loads or dynamic forces over time.
Impact Strength: ≥ 35 kJ/m²
With improved impact resistance, PA12-LCF30 can better withstand sudden shocks and impact forces, providing reliable durability and longevity in high-stress environments.
Thermal Properties
Heat Deflection Temperature: Approximately 210°C
PA12-LCF30 maintains its structural integrity at high temperatures, making it well-suited for applications that require performance stability under intense heat, such as in engine compartments or industrial machinery.
Long-Term Service Temperature: Up to 140°C
With an increased service temperature range, PA12-LCF30 delivers consistent performance in environments with moderate to high-temperature fluctuations, ideal for prolonged use in demanding applications.
Chemical Stability
PA12-LCF30 offers strong resistance to various chemicals, including oils, fuels, lubricants, and solvents, making it a prime choice for environments where exposure to such substances is common. Its low moisture absorption also ensures dimensional stability in humid conditions, enhancing performance under challenging conditions.
Processing Characteristics
Like PA12-LCF20, PA12-LCF30 can be processed using conventional techniques such as injection molding, extrusion, and 3D printing. Despite the higher carbon fiber content, it retains good flow properties, allowing for high-quality and consistent parts, even with complex designs. This makes it highly suitable for precision manufacturing.
Other Characteristics
Low Water Absorption:
PA12-LCF30’s low moisture uptake contributes to its dimensional stability, which is crucial for applications in humid or wet environments.
Excellent Wear Resistance:
The increased carbon fiber reinforcement enhances wear resistance, allowing PA12-LCF30 to perform reliably under high wear conditions and extend the lifespan of parts.
Applications
Automotive Industry:
PA12-LCF30 is used in structural components, housings, brackets, and other critical parts that require superior thermal stability and strength under significant stress.
Industrial Manufacturing:
This material is ideal for components like gears, bushings, and heavy-duty parts that need exceptional stiffness, wear resistance, and the ability to handle high loads.
Consumer Goods:
Products such as tools, sporting goods, and accessories benefit from PA12-LCF30’s strength, durability, and lightweight characteristics.

Thermal Stability of PA12-LCF
PA12-LCF (carbon fiber reinforced polyamide 12) has better thermal stability than standard PA12. The addition of carbon fiber increases the heat distortion temperature (HDT) of the material, allowing it to maintain good structural integrity in high-temperature environments. At the same time, carbon fiber also improves the thermal conductivity of PA12-LCF, helping to better dissipate heat and enhancing its durability under high temperature conditions. Overall, the thermal stability of PA12-LCF makes it suitable for applications requiring high strength and heat resistance, such as the automotive, aerospace and electronics industries.
