Tóm tắt

A modal analysis of a carbon-nanotube-reinforced polymer (CNTRP) is performed using a 3D finite-element model. A multiscale finite-element model consisting of a single-walled carbon nanotube, a nonbonded interphase region, and the surrounding polymer is constructed. The modal analysis is executed with two types of boundary conditions to obtain the natural frequencies of the CNTRP, and the frequencies obtained are compared with the natural frequencies of a neat polymer. The results show a considerable growth in the natural frequencies of reinforced composites doped even with a small portion of carbon nanotubes.
