It can meet customers' requirements for wear resistance, high temperature resistance, oil resistance, solvent resistance, high pressure resistance, high speed, acid and alkali resistance, and can be customized according to drawings and samples.

Carbon fiber rollers have demonstrated significant performance advantages in high-end industrial fields due to their unique material properties. The following is a detailed analysis of its core advantages and typical application scenarios:

1. Ultra lightweight and high-strength

Weight ratio: The density is only 1.5-2.0 g/cm 3, which is 30% lighter than aluminum alloy and 70% lighter than steel. At the same time, the tensile strength can reach 3000-7000 MPa (about 5-10 times that of steel).

Application value:

High speed printing machine guide roller: reduces rotational inertia and improves printing speed (such as digital inkjet printing roller speed of over 10000 rpm)

Aerospace composite material laying equipment: reducing mechanical arm load and improving positioning accuracy

2. High rigidity and deformation resistance

Modulus characteristics: The elastic modulus is 200-600 GPa (close to titanium alloy), and the bending stiffness is 3-5 times that of metal rollers.

Technical advantages:

Precision coating machine roller: deformation less than 0.01 mm under pressure of 10-100 N/m 2, ensuring coating uniformity (such as lithium battery electrode coating)

Semiconductor wafer polishing equipment: maintain the flatness of the roller surface for a long time to avoid micro scale scratches

3. Excellent thermal stability

Thermal expansion coefficient: The axial CTE is close to zero (0.1 × 10- □/℃), much lower than that of metal (steel 11.7 × 10- □/℃). High temperature performance:

The thermal deformation of carbon fiber rollers at 200 ℃ is only 1/20 of that of metal rollers, making them suitable for high-temperature shaping equipment such as carbon fiber prepreg hot pressing rollers

Laser cutting machine guide roller: avoid size drift caused by thermal accumulation

4. Fatigue resistance and long lifespan

Cycle life: It can withstand more than 107 cycles under alternating loads, with a fatigue strength of 70-80% of the ultimate strength (usually 30-50% for metal rollers).

Economic performance:

Wind turbine blade production mold roller: life is three times longer than steel roller, reducing downtime and replacement frequency

Paper making machinery drying section roller: resistant to steam heating cycle impact

5. Corrosion resistance and environmental aging resistance

Chemical inertness: resistant to acid and alkali, salt spray, organic solvents, and no risk of electrochemical corrosion.

Special Scenario:

Marine engineering composite material winding machine roller (such as manufacturing ship propeller shaft sleeves)

Chemical pipeline winding equipment: Contact with corrosive media such as epoxy resin and curing agents

6. Dynamic performance optimization

Critical speed: Low density and high rigidity increase the critical speed by more than 50% to avoid resonance.

High speed applications:

Textile machinery high-speed stretching roller: vibration amplitude<5 μ m when speed>8000 rpm

Magnetic levitation bearing support roller: achieving micrometer level dynamic balance accuracy

Typical Industry Applications

1. In the field of new energy: fuel cell bipolar plate pressing roller, photovoltaic silicon wafer cutting guide wheel

2. Rail transit: High speed rail body composite material forming mold roller

3. Medical equipment: CT machine carbon fiber rotating anode support roller (with X-ray transparency)

technological frontier

Nano modified carbon fiber roller: adding graphene to enhance thermal conductivity (>200 W/m.K), used in 5G high-frequency circuit board laminating equipment

Intelligent carbon fiber roller: integrated strain sensor for real-time deformation monitoring and predictive maintenance

Carbon fiber rollers are replacing traditional metal rollers and ordinary composite material rollers as core components in the high-end manufacturing field due to their lightweight, high rigidity, and environmental resistance characteristics.
