Carbon Fiber

Carbon fiber sits at the top of the performance pyramid — specific strength and modulus far surpass glass fiber. T300 → T1000 covers everything from consumer (wind / automotive lightweighting / sports) to aerospace primary structure. Zhongfu Shenying / Guangwei / Hengshen have reached T800 aerospace-grade domestic production; Toray remains the high-end benchmark.

APPLICATIONS

Typical applications

WHERE

Main applications

Aerospace primary structure (wing / fuselage / doors) · Pultruded rods for wind blade spar caps · Automotive CFRP (B-pillar / battery shell / roof — HP-RTM) · High-pressure hydrogen tanks · Sports equipment · Satellite structure.

WHY

Why carbon fiber

5–10× specific strength of steel · High specific modulus · Fatigue-tolerant · Corrosion-resistant. Downsides: expensive (¥ 120-500 /kg) · Complex processes (autoclave / HP-RTM / AFP) · Strict resin requirements (epoxy / BMI / PEEK). Best when performance-to-weight is the deciding factor.
