Also known as electrical glass—is the standard glass composition used for most glass fibers. It is made from the oxides of silicon, aluminum, calcium, magnesium, and boron. It exhibits the following mechanical properties:
- Density: 2.54 g/cm3 (158.6 lb/ft3)
- Tensile strength: 3,400 MPa (490 ksi)
- Modulus of elasticity: 72 GPa (10,440 ksi)
- Percent elongation: 4.7
Is a high performance glass fiber, distinguished from E-glass primarily by its higher silica content. S-glass typically contains the oxides of silicon, aluminum, and magnesium with the following mechanical properties:
- Density: 2.53 g/cm3 (157.9 lb/ft3)
- Tensile strength: 4,600 MPa (670 ksi)
- Modulus of elasticity: 89 GPa (12,910 ksi)
- Percent elongation: 5.2
