Conductive Automotive-grade Carbon Fiber Roving CWP400-1000

>> Carbon Fiber Roving is a collection of continuous carbon fiber filaments grouped together without any significant twist. These filaments are typically made from precursors such as polyacrylonitrile (PAN), pitch, or viscose. The most common is PAN-based carbon fiber roving. After a series of processes including polymerization, spinning, oxidation, carbonization, and sometimes graphitization, the precursor material is transformed into high-performance carbon fibers that make up the roving.

FAQ

How does CWP400-1000’s conductivity compare to metal materials like aluminum?

While aluminum has lower resistance (~2.7Ω/sq), CWP400-1000 offers a better strength-to-weight ratio—critical for automotive applications where weight savings outweigh absolute conductivity needs.

Can CWP400-1000 be used in electric vehicle (EV) battery packs?

Yes. Its conductivity dissipates static charges, and its chemical resistance protects against electrolyte leaks; it also reinforces the battery housing to prevent deformation in collisions.

Is the conductivity of CWP400-1000 affected by humidity?

No. Its surface treatment creates a hydrophobic layer, so conductivity remains stable even in high-humidity environments (e.g., coastal areas or rainy climates).

Suitable Production Process

12K Fiber Bundling: Individual carbon filaments are grouped into 12K tows, ensuring consistent conductivity and tensile strength.

Oxidation & Carbonization: Tows are oxidized (200–300°C) to stabilize structure, then carbonized (1200–1500°C) to enhance conductivity by increasing carbon content (>95%).

Surface Treatment: Plasma oxidation creates micro-pores on fiber surfaces, improving both resin adhesion and electrical contact between tows.

Woven Roving Formation: Tows are woven into a dense structure, with post-weaving curing to lock in conductive properties; final cutting is done with anti-static tools to avoid charge buildup.

Characteristics

Reliable Electrical Conductivity: Surface resistance <100Ω/sq, effective for static dissipation in automotive paint booths and EMI shielding in 5G device casings.

High Tensile Strength: 3200MPa tensile strength supports heavy loads, making it suitable for automotive door frames and battery housing structural reinforcement.

Low Density: At 1.85g/cm³, it reduces automotive weight by 30% compared to steel, improving acceleration and fuel economy.

Chemical Resistance: Resists gasoline, motor oil, and battery electrolytes, ensuring long-term performance in under-hood and battery compartment applications.
