Overview

Chopped carbon fibre strands are short segments of carbon fibres that are typically cut to specific lengths, ranging from a few millimetres to several centimetres. These strands retain the high-strength, lightweight, and stiffness properties of continuous carbon fibres, making them an excellent reinforcement material for various composite applications.

The production process of chopped carbon fibre strands involves chopping continuous carbon fibre to the desired length. These strands can then be mixed with various matrices such as thermosetting resins, thermoplastic polymers, or concrete. This integration creates composite materials with enhanced mechanical properties, including improved tensile strength, impact resistance, and dimensional stability.

Properties

  • High Strength: Provides significant reinforcement, enhancing the mechanical properties of composites.
  • Lightweight: Maintains a low density, contributing to lightweight composite materials.
  • Stiffness: Offers high modulus of elasticity, ensuring rigidity and structural integrity.
  • Thermal Conductivity: Efficiently dissipates heat, suitable for thermal management applications.
  • Electrical Conductivity: Conducts electricity, making it ideal for electronic applications and electromagnetic shielding.
  • Corrosion Resistance: Resists corrosion, ensuring durability in harsh environments.
  • Chemical Resistance: Withstands exposure to various chemicals without degrading.
