Carbon membranes are typically produced by pyrolyzing various thermosetting polymeric materials, including polyimides [2], cellulose acetate [3], furfuryl alcohol [4], and phenol-formaldehyde [5], etc. under a variety of pyrolysis conditions.
Pyrolysis conditions were varied in accordance with the type of precursor material.
Variation of d spacing can indicate the graphitization degree of carbonaceous materials.

This paper deals with the stochastic nonlinear free vibration response of functionally graded materials (FGMs)  beam subjected to thermal loadings with uncertain material properties subjected to uniform and nonuniform temperature changes with temperature independent (TID) and dependent (TD) material properties.
System properties such as material properties of each constituent’s material and volume fraction index are taken as independent random input variables.
It is assumed that FGM behaves like heterogeneous composite materials and the effects of constituent’s materials are detected separately using power index law.
