Epoxy/Carbon Fiber (CFRP) vs PE-LLD (Linear Low-Density Polyethylene)
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.
PE-LLD (Linear Low-Density Polyethylene)
Linear low-density polyethylene — short-chain branching via copolymerization with alpha-olefins (butene, hexene, octene). Better puncture resistance, tear strength, and seal strength than PE-LD at same density. THE modern stretch wrap and food packaging film. Also used for agricultural film, liners, bags, and blown film. Largely replacing PE-LD in film applications.
