Abstract
- Highlights This study used molecular dynamics simulations to investigate the effects of the distribution angle of graphene oxide (GO) on the mechanical properties and non‐reciprocity of composite materials. The results of uniaxial tensile tests indicated that the mechanical properties of the composites are optimal when the distribution angles of GO are at 30° and 45°. The 30° model has an elastic modulus of 5.79 MPa, which is higher compared to the other models. The 80° model, however, has much lower mechanical properties, with a modulus of 1.42 MPa lower than the 30° model. Similarly, the 50° model also exhibits poorer mechanical properties with an elastic modulus of 4.42 MPa. Additionally, the 50° model is 24% lower than the 45° model. Through simulations of shearing in different directions and with different strain rates, it was found that the sensitivity of different GO distribution angles to strain rates varies. When the distribution angle is at 45°, the mechanical non‐reciprocity of the composite material is more pronounced. Explored the mechanical properties of GO/PA66 composites at the molecular level. Revealed the microscopic mechanism of interaction between GO and PA66. The effect of GO distribution angle on uniaxial tensile properties was studied. Studied the mechanism of the effect of GO distribution angle on non‐reciprocity. [ABSTRACT FROM AUTHOR]
