MEASUREMENT OF THE DURABILITY OF GLASS FIBRE

The measurement of glass fibre strength in composites

Scanning electron microscopy provides a convenient technique for the study of glass fibre-reinforced composite fracture surfaces.This work describes how a detailed examination and measurement of the mirror zones on the fracture surfaces of the fibres themselves can be used to evaluate the fibre strength at the time of failure of the composite.The Mechanical Properties of GlassIntroduction to Glass Technology 7 Theoretical Strength of Glass Theoretical strength of glass can be calculated from the energy needed to separate a plane of atoms,see diagram Si - O covalent bonds are strong,circa 104 kcal Calculated value gives 18 GPa or 2.6 million Psi Most practical and design strengths are 1000 times less!
