| Abstract: | Square–form microfilters consisting of a two–layer porous membrane with nano–size pores and reinforced by silicon columns have been investigated. The change of layer thicknesses and reinforcement geometry modify the load–capacity of the device through the variation of strength properties. A simple thin plate model was constructed by substituting the effect of silicon columns by an equivalent third layer. Estimates for the load–capacity were made by finite element calculations. These estimates have been verified by experimental results. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) |
