Resumen:
High structural damping capacity is an important design parameter for all machine-elements and manufacturing tools [1]. Reduced vibration relieves dynamic stresses and improves system performance and reliability in high performance composites. Studies have shown that nanocomposites containing single-wall or multi-wall carbon nanotubes (SWCNT and MWCNT) can achieve high damping capacity by taking advantage of the weak bonding and interfacial friction between individual nanotubes and the matrix, without sacrificing mechanical properties or structural integrity [2].
The basic goals of this research are to evaluate the quality of CNTs dispersion in epoxy suspension and to show the effect of pristine and functionalized SWNTs dispersed in an epoxy elastomer on the damping capacity of the material in an extended temperature range.
