Basalt Fiber vs. Carbon Fiber Comparison

1. Material Properties Comparison 

• 1.1 Basalt Fiber  
  Basalt fiber is a novel fiber material made from basalt rock through high-temperature melting and wire-drawing processes. Its advantages include:  
  High Strength: Tensile strength up to 4,000 MPa, 5 times higher than steel and 1.5 times higher than carbon fiber.  
  High-Temperature Resistance: Withstands temperatures exceeding 1,200°C, whereas carbon fiber degrades at around 200°C.  
  Eco-Friendliness: Derived from natural minerals, it produces no harmful emissions and complies with environmental standards.  
• 1.2 Carbon Fiber
  Carbon fiber is a material composed of fibrous carbon atoms, offering the following advantages:  
  High Specific Strength: Its strength-to-weight ratio surpasses most high-strength materials, making it ideal for aerospace applications.  
  Lightweight: Density of 1.5 g/cm³**, only 1/4 that of steel and 1/7 that of aluminum, enabling significant weight reduction.  
  Corrosion Resistance: Resists chemical and water damage, even under prolonged immersion. 

2. Application Fields Comparison

• 2.1 Basalt Fiber
  Primarily used in construction, automotive, and rail transportation:  
  Construction: Reinforces bridges, tunnels, and structures to enhance load-bearing capacity.  
  Automotive: Manufactures lightweight components (e.g., car bodies, chassis) to improve fuel efficiency.  
  Rail Transportation: Used in train bodies and chassis for lightweighting and speed optimization.  
• 2.2 Carbon Fiber
  Dominates aerospace, aviation, and sports equipment:  
  Aviation: Reduces aircraft weight (e.g., fuselage, wings) to boost speed and fuel efficiency.  
  Aerospace: Critical for satellites and spacecraft to minimize weight and maximize payload capacity.  
  Sports Equipment: Creates ultra-lightweight, durable gear (e.g., golf clubs, tennis rackets, bicycle rims).  

3. Manufacturing Process Comparison 

• 3.1 Basalt Fiber 
  Process: Simplified production via high-temperature melting and wire drawing.  
  Cost: Relatively low production expenses.  
• 3.2 Carbon Fiber 
  Process: Complex multi-stage procedures, including spinning, pre-impregnation, and curing.  
  Cost: Higher manufacturing costs due to energy-intensive and technical processes.  

Summary

• Basalt Fiber: Excels in strength, high-temperature resistance, and eco-friendliness, ideal for construction, automotive, and rail applications.  
• Carbon Fiber: Superior in specific strength, lightweighting, and corrosion resistance, dominating aerospace, aviation, and sports industries.
