Epoxy/Carbon Fiber (CFRP) vs PPS GF40
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.
PPS GF40
Polyphenylene Sulfide with 40% glass fiber — the ultimate under-hood engineering plastic. Service to 240°C continuous, inherently V-0 flame resistant without additives, near-zero moisture absorption (<0.02%), exceptional chemical resistance (comparable to PEEK/fluoropolymers). Trade names include Ryton R-4 (Solvay), Fortron 1140L4 (Celanese), Tedur (INEOS), TECATRON GF40 (Ensinger). Used for automotive water pump impellers, thermostat housings, EGR valves, LED reflectors, and semiconductor wafer carriers.
