Epoxy/Carbon Fiber (CFRP) vs PTFE (Teflon)
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.
PTFE (Teflon)
Polytetrafluoroethylene — the most chemically resistant polymer. Lowest friction coefficient of any solid material (~0.05-0.10). Service range -240°C to +260°C continuous. Cannot be melt-processed — must be sintered from powder (like ceramics). Very low mechanical strength. Trade name Teflon (Chemours/DuPont). Used for seals, gaskets, bearings, non-stick coatings, chemical reactor linings, electrical insulation, and lab equipment.
