Glass Physical Properties
The compression strength of glass is extremely high: 1000 N/mm2 = 1000 MPa. This means that to shatter a 1 cm cube of glass, it requires a load of some 10 tonnes. When glass is

The strength of a material is the value of the stress in which it deforms permanently. For brittle materials which generally only fracture, such as glass, it is tensile stress that is critical not compressive strength. The compression strength of glass is very high in comparison to other structural materials. Nominally around 1000 N/mm2 = 1000 MPa.
Glass typically has a tensile strength of 7 megapascals (1,000 psi). However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapascals (2,500,000 psi). This high value is due to the strong chemical Si–O bonds of silicon dioxide.
In conclusion, the properties of glass are truly remarkable. Its compressive yield strength, Young's modulus, tensile yield strength, density, ultimate compressive strength, Poisson's ratio, and ultimate tensile strength all contribute to its exceptional versatility and durability.
Fiberglass 's strength depends on the type. S-glass has a strength of 700,000 pounds per square inch (4,800 MPa) while E-glass and C-glass have a strength of 500,000 pounds per square inch (3,400 MPa). Glass has a hardness of 6.5 on the Mohs scale of mineral hardness.

Glass typically has a tensile strength of 7 megapascals (1,000 psi). However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapascals (2,500,000 psi). This high value is due to the strong chemical Si–O bonds of silicon dioxide. Imperfections of the glass, such as bubbles, and in particular surface flaws, such as scratches, have a great effect on the strength of glass and decrease it even more than for other brittle materials. The chemical composition of the glass also impacts its tensil
