GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PE-LD (Low-Density Polyethylene)
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-LD (Low-Density Polyethylene)
Low-density polyethylene — branched chain structure gives flexibility, transparency, and easy processing. THE film/packaging polymer: cling wrap, carrier bags, squeeze bottles, shrink wrap. Also used for cable insulation, agricultural film, and coatings. Lower density (0.91-0.93) and strength than PE-HD but much more flexible.
