In this study, micromechanical analysis will be performed to derive explicit solutions of the macroscopic elastic moduli and thermal expansion coefficient for composite materials, where spheroidal-coated fillers are oriented randomly in material. This is carried out by combining double inclusion method with self-consistent or Mori-Tanaka theorem. Furthermore, using these solutions, also derived materials containing various types coated different physical properties shapes. To verify validity obtained results analytical compared experimental ones a material which carbon nanotube (
