Glass Fibre Reinforced Composites
topic
GFRP (Glass Fibre Reinforced Polymer) composites achieve: tensile strength 200-1500 MPa (depending on fibre volume fraction 30-70%, architecture, matrix), modulus 20-50 GPa, specific strength exceeding aluminum and steel, design flexibility, corrosion resistance, and electrical insulation. Matrix systems: polyester (60% of applications), epoxy (aerospace, high-performance), vinyl ester (chemical resistance), and thermoplastics (PP, PA6, PBT for automotive).
Role
GFRP combines glass fibre properties with polymer matrix creating structural materials with tailored anisotropy, enabling lightweighting in automotive (20-30% weight reduction), renewable energy (wind turbine blades 40-80 m length), and infrastructure.
