Epoxy/Carbon Fiber (CFRP) vs PE 100 (HDPE Pipe Grade)
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 100 (HDPE Pipe Grade)
High-density polyethylene pipe grade with MRS (Minimum Required Strength) of 10 MPa at 20°C/50 years. The global standard material for pressurized gas and water distribution pipelines (DN 20 to DN 2000). Bimodal molecular weight distribution provides excellent ESCR (Environmental Stress Crack Resistance), slow crack growth resistance and impact strength. SDR ratings from 7.4 to 26. Fusion-weldable (butt, electro, socket). Operating temperature -40°C to +60°C. Compliant with ISO 4427 (water) and ISO 4437 (gas).
