(OP)
If I had a sheet metal plate 5"x5"x .023" thick what thickness would I be looking for to get the same strength in plastic ?? 30% more thickness 45% thicker ???
thanks, Phk

When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Thickness
This could help in lessening the thickness required on the plastics
RE: Thickness
The design criterion should be max deflection under load, whether you have a metal plate or a ribbed plastic plate. Of course, the stresses need to be manageable under both systems. Another variable is neat polymer or glass reinforced.

RE: Thickness
Before any sensible comment can be made, details of critical properties and the environment of use need to be considered.
The temperature of the environment, and the load, and wether the load is constant or cyclic are most critical, as is the avaliable space for ribs. Does it need to be clear, or flame retardant? Is it in contact with any chemicals, including water? Which aspect of "STRENGTH" is being refered to, impact strength, tensile strength, flex modulus?
