Super resilience of a compacted mixture of natural graphite and agglomerated carbon nanotubes under cyclic compression

We have prepared and evaluated the performance of natural graphite (NG)/agglomerated carbon nanotubes (ACNTs) composite materials for future mechanical dampening devices. The mechanical performance of a compressed mixture of NG and ACNTs was examined over the pressure range of 30–300 MPa. NG–ACNT composite materials showed improved performance over the ACNT materials alone. Nanocomposites containing 5% NG mixed with ACNTs had an expansion ratio of 2.7 and illustrated a lower loss of resilience as compared to the ACNTs alone, 7% loss versus 34% loss, respectively.
