Abstract
Combined with the experimental data from previous study,a bilinear isotropic hardening model of glass fiber reinforced polyamide 6(PA6/GF)composites was established,and the effect of glass fiber(GF)content on the mechanical properties of the composites was studied,which can provide a reference for the simulation analysis and experimental design of PA6/GF composites.Firstly,based on the finite element analysis of Ansys,the element model of PA6/GF composites was established from a microscopic perspective,and the results showed that the composites had isotropic characteristics.Then,the bilinear isotropic hardening model was used to simulate and analyze the bending performance and yield performance of the splines,and the results showed that the bending strength was basically consistent with the experimental data,and the yield strain was smaller than the engineering strain,which was in line with the theoretical law.Finally,the effect of GF content on the mechanical properties of PA6/GF composites was studied through the simulation results.The results showed that with the increase of GF content,the tensile strength of the composites gradually increased,when the GF mass fraction reached 40%,the tensile strength reached 207.5 MPa,which was about three times that of pure PA6,and the impact strength of the composites increased first and then decreased with the increase of GF content,and when the GF mass fraction was 35%,the impact strength of the composites reached 21.6 kJ/m2.关键词
