GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PA6-GF15
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-GF15
Polyamide 6 with 15% short glass fiber reinforcement — moderate stiffness increase (E-Mod ~5.5 GPa vs 2.7 unfilled) while retaining good impact strength and elongation. Better toughness than higher-filled grades (GF30, GF50). Trade names: Ultramid B3EG3 (BASF), Zytel 73G15 (DuPont). Used for structural clips, housings, brackets, and under-hood automotive parts where moderate stiffness with good impact is needed.
