Ikhtisar

Glass fiber reinforced polymer (GFRP) composites are manufactured by combining continuous or chopped glass fibers with thermoset or thermoplastic resin matrices. E-glass (electrical grade, borosilicate composition) accounts for over 90% of all glass fiber production. Glass fibers are drawn from molten glass through platinum bushings at speeds up to 50 m/s, producing filaments 5-24 micrometers in diameter. GFRP composites are used in wind turbine blades, boat hulls, automotive body panels, construction, and piping.

Proses Kimia

E-glass batch (SiO2 54%, Al2O3 14%, CaO 22%, B2O3 10%) is melted in a furnace at 1,400 degrees C and fed to platinum-rhodium bushings with 200-8,000 nozzles. Molten glass streams are attenuated into fibers by high-speed winding, coated with a silane sizing agent, and collected as rovings or chopped strands. Composites are formed by pultrusion, filament winding, resin transfer molding, or hand lay-up.

SiO2 + CaCO3 + Al2O3 + B2O3 ->[1,400 degrees C] Amorphous borosilicate glass melt -> Glass fibers (physical drawing, no chemical reaction in fiberization step)

Bahan Baku

  • Silica sand (SiO2) — Sand mining (high purity) (Glass former (54% of E-glass))
  • Limestone (CaCO3) and kaolin (Al2O3) — Quarrying (Glass modifiers)
  • Polyester or epoxy resin — Petrochemical synthesis (Matrix material for composites)

Produk Akhir

  • Glass fiber rovings and mats — Wind turbine blades, boat hulls, automotive, construction (E-glass tensile strength 3.4 GPa, density 2.54 g/cm3)

Environmental Impact

Glass fiber production is energy-intensive due to the melting temperature. Boron emissions from E-glass melting require scrubbing. GFRP waste is difficult to recycle -- landfilling remains the most common disposal method. Newer boron-free E-CR glass reduces environmental impact of melting.

Pertimbangan Keselamatan

Inovasi Terbaru

Boron-free E-CR glass offers improved corrosion resistance and eliminates boron emissions.
Thermoplastic matrix composites (glass fiber/PP) enable recyclability.
Basalt fiber from volcanic rock is emerging as a cheaper, greener alternative to E-glass.
