Epoxy/Carbon Fiber (CFRP) vs PA6-GF15
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.
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.
