The compression strength of glass is very high in comparison to other structural materials. Nominally around 1000 N/mm2 = 1000 MPa. 5, which gives flat glass a mass of 2. 5 kg per m2 per mm of thickness, or 2500 kg per m3. When glass is. . Why is glass attractive for PV? PV Module Requirements – where does glass fit in? Seddon E. of Sodium Meta-silicate-Silica Glasses. Perform bending test in liquid nitrogen [77 K] to zero chemical effects. For brittle materials which generally only fracture, such as glass, it is tensile stress that is critical not compressive strength.
