ABSTRACT
This paper deals numerical simulations of composite material with Polyphenylene sulfide matrix and carbon and glass fibres; the main goal is determine ability of using proposed composite materials in airframe structure by numerical simulations, to predict the elastic properties of composite, CADEC software is used to show the effect of fiber type, number of layers and fiber orientation on the elastic properties. For this purpose the computational simulations by ANSYS 13 were carried out. The results show that the ability of using composite materials under study as skin of wing of aircraft under effects of pure inertial loads.

Key words: Polyphenylene sulfide, ANSYS, aircraft, numerical simulation, skin of wing.
