Opening on Industry Technical Pain Points: Bottlenecks in Enhancing the Performance of Carbon Fiber Products
The performance enhancement of carbon fiber industrial products faces three major technical pain points:
STEP 1: Balance between material performance and costThe tensile strength of carbon fiber can reach 3.5-7.0 GPa, but its high cost restricts large-scale application. How to reduce costs while ensuring performance is an urgent issue for the industry to address.
STEP 2: Limitations of the Design Calculation MethodTraditional design methods struggle to accurately predict the stress distribution in carbon fiber products under complex working conditions, resulting in shortened product lifespans or material waste.
STEP 3: Stability of Manufacturing ProcessThe manufacturing of carbon fiber products involves processes such as prepreg laying and curing molding, with fluctuations in process parameters directly affecting product performance. For example, a curing temperature deviation exceeding ±5℃ may result in a reduction of over 20% in interlaminar shear strength.
Nanjing Baigang Composite Materials Co., Ltd. has successfully broken through the aforementioned bottlenecks through technological innovation, achieving performance optimization of carbon fiber products.

For example, in the manufacturing of textile machinery carbon fiber guide rollers, by optimizing the curing temperature profile (120℃/2h → 180℃/1h → natural cooling), the interlaminar shear strength has been increased to over 80 MPa.
The company has passed ISO9001:2000 quality system certification, with an annual output value of 10 million yuan. Its products are widely used in fields such as wind power generation, cooling tower fans, and textile machinery, with over 4,000 drive shafts delivered in total and a customer satisfaction rate exceeding 98%.

FAQ Q&A Technical Selection Guide: Key Parameters and Selection Recommendations for Carbon Fiber Industrial Products
Q1: How to choose the specifications of carbon fiber products?
A1: The specification selection for carbon fiber products requires consideration of the following parameters:
- Diameter: Φ40mm-Φ600mm, customizable according to customer needs
- Length: Up to 10 meters, suitable for large equipment
- Tensile strength: 3.5-7.0 GPa; high-strength models are suitable for high-load scenarios.
For example, the carbon fiber connecting shaft for wind turbines should select a model with a diameter of Φ200 mm, a length of 8 meters, and a tensile strength of 5.0 GPa to meet the 20-year lifespan requirement.
Q2: What are the precautions for the manufacturing process of carbon fiber products?
A2: The manufacturing process requires focused attention on the following aspects:
- Prepreg laying: It is necessary to control the interlaminar angles (usually alternating 0°/90°) to enhance shear resistance performance
- Curing and molding: The curing temperature must be strictly controlled within ±3℃ to avoid performance fluctuations.
- Post-processing: Surface grinding and coating treatment are required to enhance corrosion resistance.
For instance, in the manufacturing of carbon fiber rollers for papermaking machinery, the product lifespan was increased from 5 years to 8 years by optimizing the lay-up angles and curing temperature.
Q3: How to verify the performance of carbon fiber products?
A3: Performance validation requires passing the following testing indicators:
- Tensile strength: ≥3.5 GPa (ASTM D3039 standard)
- Interlaminar shear strength: ≥50 MPa (ASTM D2344 standard)
- Fatigue life: ≥10^7 cycles (ISO 13527 standard)
Each product from Nanjing Baigang Composite Materials Co., Ltd. undergoes the aforementioned inspections before leaving the factory to ensure that its performance meets the standards.
