Polycarbonate PC CF20 Overview
Modified Polycarbonate PC CF20 is a high-performance composite reinforced with 20% carbon fiber (CF), combining the toughness of polycarbonate (PC) with the strength and stiffness of CF. This material exhibits enhanced mechanical properties, including high tensile strength (~120 MPa), improved heat resistance (HDT ~145°C), and low thermal expansion, making it ideal for demanding applications.
Suitability for FGF
FGF, a large-format 3D printing process, requires materials with excellent melt stability, layer adhesion, and minimal warping. PC CF20 excels in these areas due to:
-
Enhanced Flow and Adhesion: The CF filler improves melt flow while maintaining interlayer bonding, critical for FGF’s coarse deposition. Data shows a shear viscosity reduction of ~30% compared to neat PC, enabling smoother extrusion.
-
Low Warpage: The CF’s stabilizing effect reduces shrinkage (~0.3% vs. 1.2% for unfilled PC), minimizing distortion in large prints.
-
Mechanical Retention: Even with FGF’s layer-by-layer approach, PC CF20 retains ~85% of its tensile strength versus injection-molded parts, outperforming unreinforced polymers.
These properties make Polycarbonate PC CF20 a robust choice for FGF, particularly in automotive, aerospace, and tooling applications where dimensional stability and strength are paramount.
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.
