Nondestructive Sensing Evaluation of Ni Nanowire Strands and Carbon Nanotube/Epoxy Composites Using Electro-Micromechanical Techniques

Electro-Micromechanical 시험법을 이용한 Ni Nanowire Strands 및 Carbon Nanotube 강화 에폭시 복합재료의 비파괴 감지능 평가

Nondestructive damage sensing and load transferring mechanism of Ni nanowire strands and multi-wall carbon nanotube (MWCNT)/epoxy composites were investigated using electro-micromechanical techniques. MWCNT composite was especially prepared for high volume contents, 50 vol % of reinforcement. Electro-micromechanical techniques were applied to measure apparent modulus and contact resistance of Ni nanocomposites with their alignment and different diameters, and adding contents. Applied cyclic load affected on apparent modulus and electrical properties on nanocomposites due to various inherent properties of each CNMs. Contact resistivity on humidity sensing was a good indicator for monitoring as for multifunctional applications. Further study on actuation as well as sensing will be investigated for the following work continuously.
