Abstract :In this study, mechanical properties of basalt fiber (BF) and glass fiber (GF) reinforced polyamide66 (PA66) matrix composite materials were investigated using the mean field homeogenization (MFH) method. BF and GF reinforced PA66 matrix composite materials with 5, 10, 20, 40 wt% additives were modeled using MFH based Digimat-mean field (Digimat-MF) software. With Digimat-MF software, micromechanical modeling of composite materials was performed and maximum tensile strength and elastic modulus were calculated. In addition, representetive volume element (RVE) modeling of composite materials was performed using Digimat-finite element (Digimat-FE) software. Then, micro-scale damage analysis (stress and strain regions) were evaluated on RVE models of composite materials. According to the results obtained, the mechanical properties of BF reinforced PA66 (BF/PA66) and GF reinforced PA66 (GF/PA66) composite materials were compared. The results showed that BF/PA66 composite materials exhibited superior mechanical properties compared to GF/PA66 composite materials at all additive ratios.
