Driving Efficiency and Sustainability—Metal-Based Composites
By adopting weight-reduction strategies that involve material substitution and design innovation, we can achieve significant improvements in fuel efficiency, emissions reduction, and overall operational efficiency. This approach is a key strategy for optimizing product performance and environmental sustainability in the automotive, robotics, and aerospace industries.
High-strength, high-conductivity aluminum alloy
Nano-carbon (CNT/Gr) exhibits paramagnetic behavior along its long axis and can rotate under the influence of a magnetic field, aligning itself parallel to the direction of the magnetic field. Surface modification of CNT/Gr—such as coating with metallic particles like Co or Ni—can enhance its paramagnetic properties and reduce the magnetic field strength required for alignment.
By inducing an ordered and controllable arrangement of randomly oriented CNTs/Gr, it is possible to increase the mean free path of electron movement within the nanocarbon material, reduce phonon scattering in the radial direction, and enhance electrical conductivity. This approach enables simultaneous improvement of both the mechanical and electrical properties of the material.
The orientation degree of nanocarbon was characterized using SEM. The orientation index was defined as the average value of cos θ (where θ represents the angle between an individual nanocarbon particle and the direction of the magnetic field; measurements were performed using ImageJ software). When the orientation index exceeds 0.96, the sample performance meets the specified criteria.
