Epoxy/Carbon Fiber (CFRP) vs PEEK CF30
Side-by-side chemical composition and mechanical property comparison.
Overview
Epoxy/Carbon Fiber (CFRP)
Carbon fiber reinforced epoxy — the benchmark structural composite material. Unidirectional ply: tensile strength 1500–2000 MPa, modulus 120–150 GPa at density 1.55 g/cm³ (5x stronger than steel at 1/5 the weight). Quasi-isotropic layup: UTS ~600 MPa, E ~50 GPa. Autoclave-cured prepreg (aerospace) or infusion/RTM (industrial). Used in aerospace primary structures (fuselage, wings), Formula 1 chassis, bicycle frames, wind turbine blades, pressure vessels (Type IV) and high-end sporting goods. Fiber types: T300, T700, T800, M40J, M55J.
PEEK CF30
PEEK with 30% short carbon fiber — the stiffest and strongest injection-moldable thermoplastic compound available. E-Mod ~24 GPa (vs 11 GPa GF30, 4.1 unfilled). UTS ~212 MPa. Electrically conductive (antistatic/EMI shielding). Outstanding wear/friction properties. Trade names: Victrex 450CA30, TECAPEEK CF30 (Ensinger), KetaSpire CF30 (Solvay). Used for semiconductor wafer handling, bearing cages, compressor components, and metal-replacement structural parts.
