In order to reveal the influence of spatial non-uniform distribution effect of carbon nanotubes on micro-scale mechanical and electrical properties of carbon nanotube reinforced composites, the fast Fourier transform (FFT) method was used to establish FFT micro-scale mechanical-electrical coupling model. Compared with the experimental data and theoretical calculation results in the literature, the efficiency, accuracy and applicability of the model were verified. The effects of spatial non-uniform distribution of bending and orientation of one-dimensional nano-conductive fillers (1D-NCF) on the mechanical and electrical properties of composites were investigated. The results show that when the volume fraction of 1D-NCF is ≤2%, equivalent conductivity decreases first and then increases with the increase of 1DNCF agglomeration rate, and increases with the increase of maximum orientation angle. When the volume fraction of 1DNCF is ≥3%, saturated equivalent conductivity decreases with the increase of agglomeration rate and maximum orientation angle. The study provides a reference for optimal design and construction of fiber-based flexible mechanical sensing materials. [ABSTRACT FROM AUTHOR] |
