The core difference between glass fiber and carbon fiber

2026-01-28
Glass fiber and carbon fiber are two distinct types of reinforcing materials, with their key differences lying primarily in raw materials and performance characteristics. Glass fiber is produced by melting glass raw materials and drawing them into filaments, offering excellent corrosion resistance, high-temperature stability, good electrical insulation, and relatively low cost. In contrast, carbon fiber is formed through the high‑temperature carbonization of organic or polymeric fibers, characterized by its light weight, exceptional strength, high stiffness, superior fatigue resistance, and a low coefficient of thermal expansion. In short, glass fiber emphasizes corrosion and heat resistance, while carbon fiber prioritizes lightweighting and enhanced strength and stiffness.
