GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PA6 (Nylon 6)
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.
PA6 (Nylon 6)
Polyamide 6 (Nylon 6) — the most widely used engineering thermoplastic. Excellent combination of mechanical strength, toughness, wear resistance, and chemical resistance. Properties are moisture-sensitive — conditioned (50% RH) values are significantly lower than dry values. Trade names include Ultramid B (BASF), Akulon (DSM), Zytel (DuPont). Used for gears, bearings, bushings, cable ties, structural brackets, and automotive under-hood components.
