碩士 === 國立中正大學 === 機械工程所 === 94 === The mechanical properties of carbon nanotube metal matrix composites were studied using molecular dynamics simulations. The atomic models were constructed in order to investigate several effects, i.e. carbon nanotube weight ratio effect, chiral effect and the adhesion between nanotube and metal matrix. It was found that the Young’s modulus of composites increase as carbon nanotube weight ratios increase. The Young’s modulus of armchair carbon nanotube composites were found to be higher than those with zigzag and chiral carbon nanotubes for similar weight ratios. It was concluded that the Young’s modulus of composites would improve if the adhesion between nanotube and matrix becomes stronger.
