What’re PA66 CF30 compounds?

PA66 CF30 is a polyamide 66 (nylon 66) product filled with 30% carbon fiber. Features include: conductive, high strength, wear-resistant, high strength, can be used in injection molding, extrusion molding processes, light density, and diversified product structures.

1. The density of PA66/CF composite material is less than 1.3. Compared with the density of steel (7.85), it is less than one-sixth of its density, achieving the purpose of lightweight and conducive to energy saving and consumption reduction.
2. In the PA66/CF composite material system, the length of CF is about 0.5~0.7mm, the interface between the PA66 matrix and the carbon fiber is fully combined, the nylon 66 is well wrapped around the carbon fiber, the fracture surface of the PA66/CF sample is relatively rough, and the PA66/CF sample is relatively rough. CF composite materials are tough materials.
3. Compared with PA66, the mechanical properties of PA66/CF composite materials have been greatly improved. When 4 bundles of CF are added, the tensile strength of PA66/CF reaches 200.2MPa, which is approximately 130% higher than that of nylon 66, and the elongation at break is 3.3%; the bending strength reaches 280.2MPa, which is approximately 211% higher than PA66. The bending die The amount reached 13560.8MPa, which is approximately 362% higher than PA66.

Advantages of PA66 CF30 Composites

PA66 CF30 offers several advantages over traditional materials:
1. High Strength and Stiffness: The addition of carbon fiber significantly increases the strength and stiffness of the PA66 matrix. This results in a material with enhanced mechanical properties, making it suitable for applications requiring high structural integrity.
2. Lightweight: Despite its enhanced strength and stiffness, PA66 CF30% remains relatively lightweight compared to metals like steel or aluminum. This makes it an attractive choice for applications where weight reduction is critical, such as automotive and aerospace industries.
3. Improved Dimensional Stability: The incorporation of carbon fiber helps reduce dimensional changes due to temperature variations, moisture absorption, or other environmental factors. This improved stability ensures tighter tolerances and better part consistency in manufacturing processes.
4. Enhanced Chemical Resistance: PA66+CF30 exhibits better resistance to chemicals, oils, and solvents compared to unfilled PA66. This makes it suitable for applications exposed to harsh environments or chemical exposure.
5. Excellent Thermal Properties: Carbon fiber reinforcement enhances the thermal conductivity of the material, leading to improved heat dissipation. This property is advantageous in applications requiring thermal management, such as electronic components or automotive parts.

6. Reduced Wear and Abrasion: The presence of carbon fiber improves the wear resistance of 30%CF PA66, making it suitable for applications subject to friction and abrasion, such as gears, bearings, and bushings.

7. Good Electrical Insulation: PA66 30%CF maintains the electrical insulation properties of PA66 while offering improved mechanical strength. This combination makes it suitable for electrical and electronic applications where insulation and structural integrity are essential.

8. Design Flexibility: Composite materials like PA66 CF30 offer greater design freedom compared to traditional materials. Manufacturers can create complex shapes and features without sacrificing structural performance, allowing for innovative designs and cost-effective manufacturing processes.
