In this paper the numerical simulations of microcel lular injection molding process for polymer composite with glass fiber for variable content of pores were carried out. In order to evaluate the strength of the three -phase composite structure (polypropylene PP as a matrix, 20% wt. of glass fiber GF and 1-9 % vol. of the pores) a microstructural analysis was performed and streng h calculations were conducted using the Mori-Tanaka homogenization model. The analyzed product (the base of industrial mop) was subjected to the loading in Ansys 14.5 commercial code, considering the impact of pores content on its mech anical properties. Furthermore, the paper presents the visualization of calculated composite microstructure for variable pores contents.
