High strength glass High strength glass elierabiaad (Materials) (OP) 20 Jun 15 10:31 I need strong clear glass that can withstand 150 kilo Newton per meter squared (or 22 psi). Limited by the weight 270 kg per meter square (or 55.4 lbs/ft2). Open to suggestion. Glass must be 4,100 X 2,700 mm. RE: High strength glass dwallace1971 (Aerospace) 16 Jul 15 13:55 What is the application? Are there any limitations on thickness or optics? "On the human scale, the laws of Newtonian Physics are non-negotiable" RE: High strength glass glass99 (Structural) 4 Aug 15 20:12 Chemically strengthened soda lime glass or alumino silicate glass can have a failure strength in the range of 40-120ksi depending on the processing. That is a tensile strength, not a surface load. If you have a load normal to the plane of the glass of 22psi, then its a different story. There is a chem tank I know of which is 5m long. Knowing the application would help.
