GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PTFE (Teflon)
Side-by-side chemical composition and mechanical property comparison.
Overview
GFRP / GFK (Glass Fiber Reinforced Epoxy)
Glass fiber reinforced epoxy composite — the cost-effective structural composite for industrial, marine and construction applications. E-glass fiber in epoxy matrix. Unidirectional: UTS ~1000 MPa, E ~40 GPa. Quasi-isotropic layup: UTS ~300 MPa, E ~18 GPa. Density 1.8–2.1 g/cm³. Electrically insulating (unlike CFRP). Used for boat hulls, wind turbine blades, chemical tanks/pipes, architectural panels, ladders, gratings, automotive body panels and electrical insulation structures.
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.
