Epoxy/Carbon Fiber (CFRP) vs PE-UHMW
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.
PE-UHMW
Ultra-High Molecular Weight Polyethylene — the highest impact-strength thermoplastic. Molecular weight 2-6 million g/mol. Self-lubricating, extremely wear-resistant (15x better than carbon steel), and chemically inert. Used for hip/knee implant bearings, conveyor guides, dock fenders, chute liners, food processing equipment, and ballistic armor (Dyneema/Spectra fiber form).
