GFRP / GFK (Glass Fiber Reinforced Epoxy) vs PC (Polycarbonate)
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.
PC (Polycarbonate)
Polycarbonate — the transparent high-impact engineering plastic. Amorphous with outstanding impact strength (virtually unbreakable at room temp), optical clarity (~90% light transmission), and good heat resistance (Tg 145-150°C). Trade names include Lexan (SABIC), Makrolon (Covestro). Used for safety glazing, machine guards, automotive headlamp lenses, CDs/DVDs, riot shields, and electronic housings.
