GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PE 100 (HDPE Pipe Grade)
Side-by-side chemical composition and mechanical property comparison.
Overview
GFRP / GFK (Glass Fiber Reinforced Epoxy)
Glass fiber reinforced epoxy composite — the cost-effective structural composite for industrial, marine and construction applications. E-glass fiber in epoxy matrix. Unidirectional: UTS ~1000 MPa, E ~40 GPa. Quasi-isotropic layup: UTS ~300 MPa, E ~18 GPa. Density 1.8–2.1 g/cm³. Electrically insulating (unlike CFRP). Used for boat hulls, wind turbine blades, chemical tanks/pipes, architectural panels, ladders, gratings, automotive body panels and electrical insulation structures.
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).
