Richard’s chamber separator disk geometry, using polycarbonate, 20% glass filled

An analysis of a CSD based on geometry specified by Richard Nakka. In this run glass filled polycarbonate was used as the material, with the following properties:

Elastic modulus in X: 1200000 psi
Poisson’s Ration in XY: 0.37
Tensile Strength in X: 17100 psi
Compressive Strength in X: 18000 psi
Yield Strength: 17400 psi

Loaded from the bottom with 1000psi, displacement plot:

In short, it is unsurprisingly better than the weaker delrin, but retains areas with factors of safety lower than desired.
