Polymer air lag
WebPerformance. The performance of a gas permeation membrane process is determined primarily by two factors: (1) permeance ( gas permeation rate /membrane area/gas partial pressure difference) and (2) selectivity (ratio of permeances for a gas pair). Permeance is equal to the gas permeability of the membrane material divided by the effective ... WebSep 18, 2007 · In this article the viscoelastic behavior of carbon nanotubes (CNTs) reinforced composites is investigated theoretically by using the three-phase concentric cylindrical shell model along with shear-lag arguments. The parameters which influence the fiber stress, the matrix stress and the interfacial stress have been revealed. The aspect …
