In this study, CFRPs (carbon fiber reinforced plastic) reinforced with ANFs (aramid nanofibers) were fabricated to investigate the dynamic mechanical analysis (DMA). Also, CFRPs reinforced with MWCNTs (multi-walled carbon nanotubes) were produced to be compared for filler effects in the composites. Those nano filler reinforced CFRPs were made by a hand-ray up method and vacuum bagging process. Through the tan δ of DMA, the damping property was evaluated. CFRPs reinforced with ANFs showed a higher tan δ than the neat CFRP by the effect of boundary sliding (filler-filler) and interfacial sling (filler-matrix). Improving damping property from tan δ results was expected to lead the energy dissipation when the external force was applied.
