Carbon Fiber Rod
Carbon Fiber Rod Product Description
I. Product Overview
1. What Are Carbon Fiber Rods?
Carbon fiber rods (CFR) are high-performance cylindrical structural materials manufactured from carbon fiber-reinforced polymer (CFRP). Composed of carbon fiber filaments (over 90% carbon content) bonded by a polymer matrix (e.g., epoxy or polyester resin), they are engineered through advanced processes to deliver exceptional strength-to-weight ratios.
2. Manufacturing Processes
Pultrusion: Continuous fibers are resin-impregnated, pulled through a heated die, and cured—ideal for producing long, straight rods with high dimensional precision.
Filament Winding: Resin-coated fibers are wound around a mandrel at controlled angles, suitable for irregular or variable cross-section rods.
Compression Molding: Pre-impregnated fibers (prepreg) are cured under high temperature and pressure in molds, enabling complex custom geometries.
3. Product Classification
By Modulus: Standard modulus (230-240 GPa), intermediate modulus (280-300 GPa), high modulus (350+ GPa).
By Surface Treatment: Smooth, sandblasted, or threaded rods.
By Functionality: Electrically conductive, antistatic, or flame-retardant variants.
4. Core Properties
Lightweight & High Strength: Density of 1.5-1.7 g/cm³ (1/4 of steel, 2/3 of aluminum) with tensile strength exceeding 5x that of steel.
Corrosion Resistance: Immune to acids, alkalis, salts, and organic solvents, ideal for harsh environments.
Low Thermal Expansion: Exceptional dimensional stability across temperatures (-50°C to 150°C), critical for precision instruments.
Design Flexibility: Mechanical properties can be tailored via fiber orientation and resin selection.

Advantages Of Carbon Fiber Rod
1. Performance Benefits
Mechanical Superiority:
Tensile strength: 3,000-7,000 MPa (vs. 200-600 MPa for aluminum alloys).
Flexural modulus: 200-500 GPa, with fatigue resistance surpassing metals.
Weight Reduction Benefits:
In aerospace, reducing 1 kg saves ~$100,000/year in fuel costs (e.g., satellites).
Automotive weight reduction by 10% improves fuel efficiency by 6%-8%.
Environmental Adaptability:
Operational range: -50°C to 150°C (high-temperature resins extend to 300°C).
UV-resistant coatings enable 20+ years of outdoor service life.
2. Economic Benefits
Lower Lifecycle Costs: Initial cost is 3-5x higher than aluminum, but reduced maintenance and extended lifespan ensure long-term value.
Efficient Processing: Enables integrated molding, eliminating traditional metalworking steps like machining and welding.
3. Sustainability
Recyclable via pyrolysis to separate fibers from resins, aligning with circular economy principles.
Lightweight designs reduce energy consumption and CO₂ emissions, supporting global decarbonization goals.
