Material (CF40-PP) Overview
Electric Conductive CF40-PP Composites are advanced polymer-based materials composed of polypropylene (PP) reinforced with 40% carbon fiber (CF) to achieve enhanced electrical conductivity and mechanical strength. The incorporation of carbon fibers transforms the inherently insulating PP into a lightweight, conductive, and durable composite, making it suitable for applications requiring electrostatic dissipation (ESD), electromagnetic interference (EMI) shielding, and structural stability.
Performance Advantages
-
High Electrical Conductivity
-
With 40% carbon fiber loading, the composite achieves a volume resistivity of 10^2–10^4 Ω·cm, enabling effective static charge dissipation and EMI shielding (e.g., ~30–60 dB attenuation in mid-frequency ranges).
-
-
Lightweight & High Strength
-
Density ranges 1.2–1.4 g/cm³, significantly lighter than metals.
-
Tensile strength reaches 80–120 MPa, surpassing pure PP (~30 MPa) while maintaining flexibility.
-
-
Thermal Stability
-
Heat deflection temperature (HDT) improves to ~150°C (vs. ~60°C for neat PP), suitable for automotive and electronics under moderate heat.
-
-
Chemical & Corrosion Resistance
-
Retains PP’s resistance to acids, alkalis, and solvents, ideal for harsh environments (e.g., industrial sensors).
-
-
Processability
-
Compatible with injection molding and extrusion, allowing cost-effective mass production of complex parts.
-
Key Applications
-
Electronics: EMI shielding housings, antistatic trays, and connectors.
-
Automotive: Lightweight conductive components (e.g., fuel system parts, battery housings).
-
Aerospace: Structural panels with ESD protection.
-
Industrial: Corrosion-resistant sensors and machinery parts.
By balancing conductivity, weight, and manufacturability, CF40-PP composites bridge the gap between polymers and metals, offering sustainable solutions for modern industries.
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.
