제목 Mechanical and Electrical Properties of Carbon Nanotube/Polypropylene Composites by Electro-Micromechanical Techniques
초록 This study examined the sensing effects of carbon nanotubes (CNT) embedded in polypropylene (PP) matrix, and evaluated these effects to predict the lifespan of PP specimen for applications. Mechanical properties and reinforcement effects of CNT-PP composites were investigated and compared with pure PP matrix. The inherent properties of PP matrix did not change after adding CNT into PP matrix, because of low concentration of CNT fillers. In order to predict the lifespan of CNT-PP composite specimen, the change in electrical resistance of the composites was measured using loading and fatigue tests. CNT fillers exhibited good self-sensing under electro-micromechanical tests. The electrical resistance of CNT-PP composites increased significantly due to microcracks inside composites.
