SUMMARY

The yield strength of E-Glass fibre is quoted at 2000 MPa. The discussion highlights that traditional yield strength concepts may not apply due to the material's brittle nature, which results in a stress-strain curve that emphasizes ultimate strength values instead. This distinction is crucial for understanding the mechanical properties of E-Glass fibre in practical applications.

PREREQUISITES
  • Understanding of material properties, specifically tensile strength and brittleness.
  • Familiarity with stress-strain curves and their significance in material science.
  • Knowledge of composite materials, particularly E-Glass fibre.
  • Basic principles of mechanical engineering related to yield and ultimate strength.
NEXT STEPS
  • Research the mechanical properties of E-Glass fibre in composite applications.
  • Study the differences between yield strength and ultimate strength in brittle materials.
  • Explore stress-strain curve analysis for various composite materials.
  • Investigate testing standards for measuring the yield strength of fibres and composites.
USEFUL FOR

Material scientists, mechanical engineers, and composite material developers will benefit from this discussion, particularly those focused on the properties and applications of E-Glass fibre.

I have every possible value and propertie for E-Glass fibre but i can't find yeild strength anywhere

anyone know it?

I'd guess that E-glasses strain-to-failure doesn't make the traditional concept of "yield strength" that relevant, that's why you're seeing mostly ultimate strength values. More of a "brittle" stress-strain curve.
