Composite structures are finding increasing applications because of their high specific stiffness and strength. The behavior characterization of composites under different loading conditions necessitates thermo-mechanical properties of individual layers. The present work deals with determination of elastic and thermo-mechanical properties of transversely isotropic lamina using Method of Cells and comparison of the results withComposite Cylinder Assemblages .The prerequisite properties of the fibers and matrix used are referred from standard data bank to determine the relevant properties of lamina. Specially orthotropic 3D composites are characterized by nine elastic properties, these properties are determined using Method of Cells, Composite Cylinder Assemblages. It has been observed that the Method of Cells is useful for determination of the compressive strength of lamina. The results obtained using micromechanical models of Method of Cells are found upper bound for transverse properties of lamina.
