Epoxy/Carbon Fiber (CFRP) vs PP GF30
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.
PP GF30
Polypropylene with 30% short glass fiber — a cost-effective alternative to PA GF30 for applications up to ~130°C. Much cheaper base resin (PP vs PA), zero moisture sensitivity, and excellent chemical resistance. Lower strength than PA6 GF30 (UTS 80 vs 175 MPa) but sufficient for many structural parts. Trade names include Celstran PP-GF30 (Celanese), Tepex (LANXESS), Stamax (SABIC). Used for automotive front-end carriers, battery trays, HVAC components, and household appliance frames.
