Epoxy/Carbon Fiber (CFRP) vs PP-C (Polypropylene Copolymer)
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-C (Polypropylene Copolymer)
Polypropylene copolymer (random or block) — better impact resistance at low temperatures than PP homopolymer (PP-H). Random copolymer: excellent clarity for packaging. Block copolymer: high impact for automotive bumpers, containers, and household appliances. Trade names: Moplen (LyondellBasell), Hostalen (LyondellBasell). THE automotive interior/exterior polymer alongside ABS.
