Technical Specifications

GFRE (Glass Fiber Reinforced Epoxy) reinforcement is a composite material that provides superior performance to traditional steel reinforcement. Here are the key technical specifications:

  • Tensile Strength: GFRE reinforcement has an average tensile strength of 1000 MPa, providing three times the strength of conventional steel reinforcement.

  • Density: GFRE has a density of approximately 2.0 g/cm³ and weighs about a quarter of steel, making it easier to handle and use on construction sites.

  • Thermal Conductivity: GFRE reinforcement has a low thermal conductivity of 0.25 W/m·K, making it ideal for structures requiring high temperatures or extreme temperature conditions.

  • Corrosion Resistance: GFRE reinforcement does not rust, eliminating the risk of structural damage from chemical and environmental influences. It is extremely resistant to acids, salts, and alkalis.

  • Elastic Modulus: GFRE has an elastic modulus of approximately 40 GPa, providing flexibility while maintaining structural integrity.

  • Temperature Resistance: GFRE reinforcement exhibits excellent performance under high temperature conditions. It maintains its function without compromising strength in operating temperatures ranging from -40°C to +100°C.

  • Electrical Conductivity: GFRE is non-conductive, making it suitable for use in environments where electrical insulation is critical, such as MRI rooms and high-voltage installations.

  • Coefficient of Thermal Expansion: The coefficient of thermal expansion is 8 x 10⁻⁶/°C, which keeps GFRE dimensionally stable over a wide temperature range and prevents significant expansions and contractions like steel.

  • Fire Resistance: GFRE's flame-retardant properties make it suitable for applications where fire safety is a priority. It is resistant to fire and prevents the spread of fire in an emergency.
