PP CF (Polypropylene Carbon Fiber Composite) Technical Overview

1. High-Temperature Performance
PP CF maintains structural integrity at elevated temperatures with a heat deflection temperature of 160-180°C. The composite can withstand short-term exposure up to 200°C while preserving mechanical properties, making it suitable for under-hood automotive applications.

2. Enhanced Mechanical Properties

• Tensile Strength: 120-150 MPa (50% improvement over standard PP)

• Flexural Strength: 180-220 MPa

• Tensile Modulus: 8-10 GPa
  The carbon fiber reinforcement provides excellent strength-to-weight ratio for structural components.

3. Chemical Resistance
PP CF demonstrates outstanding resistance to:

• Acids and alkalis at moderate concentrations

• Automotive fluids (oils, coolants)

• Industrial solvents
  This makes it ideal for chemical processing equipment and automotive fluid systems.

4. Tribological Properties
With a friction coefficient of 0.25-0.35 and superior wear resistance, PP CF is excellent for:

• Bearing components

• Wear pads

• Sliding mechanisms

5. Dimensional Stability

• CTE: 30-40 μm/m·K

• Water absorption <0.01%
  These properties ensure reliable performance in varying environmental conditions.

6. Electrical Properties

• Volume resistivity: 10^13 Ω·cm

• Dielectric strength: 20 kV/mm
  Suitable for electrical housings and insulating components.

7. Lightweight Advantage
At 1.25 g/cm³ density, PP CF offers 40-50% weight reduction versus aluminum, improving energy efficiency in transportation applications.

Key Applications:

• Automotive: Air intake systems, battery trays, structural brackets

• Industrial: Material handling components, chemical tanks

• Consumer: Power tool housings, sporting goods

• Electrical: Connector housings, circuit board supports
