CF-PPA granules (Carbon Fiber-Reinforced Polyphthalamide) is a high-performance composite material made by uniformly dispersing short-cut carbon fibers (typically 15%-30% by weight) into a PPA matrix. PPA itself offers exceptional high-temperature resistance (HDT exceeding 280°C), mechanical strength, and chemical stability. The addition of carbon fibers further enhances rigidity, dimensional stability, and thermal conductivity, making it an ideal choice for FDM (Fused Deposition Modeling) applications requiring high load-bearing capacity and thermal endurance.
Data-Driven Advantages for CF-PPA Granules FDM Applications
-
Mechanical Performance: Carbon fiber reinforcement increases tensile strength to 120-150 MPa (compared to ~80 MPa for pure PPA) and flexural modulus to 7-8 GPa—an improvement of ~200%, making it suitable for printing structural components like gears and jigs.
-
Heat Deflection Temperature (HDT): CF-PPA achieves an HDT of 290°C (ASTM D648), outperforming most engineering plastics (e.g., ABS at 90°C) and ensuring stability in high-temperature environments.
-
Low Shrinkage: Carbon fiber reduces molding shrinkage to 0.2%-0.3% (vs. ~1.2% for pure PPA), minimizing warping and improving dimensional accuracy (±0.1 mm/m).
-
Printability: With a melt flow index (MFI) of 15-25 g/10 min (270°C/2.16 kg), it balances flowability and interlayer adhesion, enabling stable extrusion at nozzle temperatures of 300-320°C.
CF-PPA granules, with their quantifiable high strength, heat resistance, and low shrinkage, are precisely tailored to meet the stringent reliability demands of industrial FDM printing.
Surface Resistivity Comparison
Conductors < 10⁵ Ω/sq. Antistatic Materials 10⁵ ~ 10¹² Ω/sq. Insulators > 10¹² Ω/sq. Static-Dissipative 10⁶ ~ 10¹¹ Ω/sq. *Key Influencing Factors Humidity: Increased moisture can reduce resistivity (e.g., in polymers). Temperature: Affects carrier mobility (↑ heat may lower semiconductor resistivity). Surface Contamination: Dust/oils alter readings significantly. Additives: Carbon black, metallic fillers can lower resistivity. *Applications Electronics: Antistatic materials (10⁶–10⁹ Ω/sq) prevent electrostatic discharge (ESD). Aerospace: Composites must control resistivity to avoid charge buildup. Medical Devices: Insulating materials (>10¹² Ω/sq) ensure patient safety. *Examples Polypropylene (PP): ~10¹⁶ Ω/sq (excellent insulator). Carbon Fiber Composites: 10³–10⁶ Ω/sq (static dissipation). ESD Flooring: 10⁶–10⁹ Ω/sq.
Get to Know Carbon Fibers
The table presents key performance data of carbon fiber grades. T300, with a tensile strength of 3530 MPa and a tensile modulus of 230 GPa, has a relatively low tensile elongation at break of 1.5% and a body density of 1.76 g/cm³. As the grade increases, for example, T700S shows an enhanced tensile strength of 4900 MPa compared to T300, while maintaining the same tensile modulus but with a higher elongation at break of 2.1%. T800S and T1000G both have a tensile modulus of 294 GPa, and their tensile strengths are 5880 MPa and 6370 MPa respectively. T1100G stands out with the highest tensile strength of 7000 MPa and a tensile modulus of 324 GPa. Generally, with the increase in product grade, the tensile strength and modulus tend to rise, while the density remains relatively stable around 1.8 g/cm³.
