Epoxy/Carbon Fiber (CFRP) vs PC (Polycarbonate)
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.
PC (Polycarbonate)
Polycarbonate — the transparent high-impact engineering plastic. Amorphous with outstanding impact strength (virtually unbreakable at room temp), optical clarity (~90% light transmission), and good heat resistance (Tg 145-150°C). Trade names include Lexan (SABIC), Makrolon (Covestro). Used for safety glazing, machine guards, automotive headlamp lenses, CDs/DVDs, riot shields, and electronic housings.
